	)

inherited

Creates a new blank resource, but does not immediately load it.

Parameters

name	The unique name of the Resource
group	The name of the resource group to attach this new resource to
isManual	Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
loader	Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
createParams	If any parameters are required to create an instance, they should be supplied here as name / value pairs

◆ createOrRetrieve()

ResourceCreateOrRetrieveResult Ogre::ResourceManager::createOrRetrieve	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	createParams = `0`
	)

inherited

Create a new resource, or retrieve an existing one with the same name if it already exists.

Remarks: This method performs the same task as calling getByName() followed by create() if that returns null. The advantage is that it does it in one call so there are no race conditions if using multiple threads that could cause getByName() to return null, but create() to fail because another thread created a resource in between.

Parameters

name	The unique name of the Resource
group	The name of the resource group to attach this new resource to
isManual	Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
loader	Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
createParams	If any parameters are required to create an instance, they should be supplied here as name / value pairs

Returns: A pair, the first element being the pointer, and the second being an indicator specifying whether the resource was newly created.

◆ setMemoryBudget()

void Ogre::ResourceManager::setMemoryBudget ( size_t bytes )

inherited

Set a limit on the amount of memory this resource handler may use.

Remarks: If, when asked to load a new resource, the manager believes it will exceed this memory budget, it will temporarily unload a resource to make room for the new one. This unloading is not permanent and the Resource is not destroyed; it simply needs to be reloaded when next used.

◆ getMemoryBudget()

size_t Ogre::ResourceManager::getMemoryBudget ( void ) const

inherited

Get the limit on the amount of memory this resource handler may use.

◆ getMemoryUsage()

size_t Ogre::ResourceManager::getMemoryUsage ( void ) const

References OGRE_RESOURCE_GROUP_INIT.

◆ unload() [1/2]

void Ogre::ResourceManager::unload	(	const String &	name,
		const String &	group = `RGN_DEFAULT`
	)

inherited

Remarks: Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

See also: ResourceGroupManager for unloading of resource groups.

◆ unload() [2/2]

void Ogre::ResourceManager::unload ( ResourceHandle handle )

inherited

Unloads a single resource by handle.

Remarks: Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

See also: ResourceGroupManager for unloading of resource groups.

◆ unloadAll() [1/2]

void Ogre::ResourceManager::unloadAll ( bool reloadableOnly = true )

inlineinherited

Unloads all resources.

Remarks: Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

See also: ResourceGroupManager for unloading of resource groups.

Parameters

reloadableOnly If true (the default), only unload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't load them later. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later.

See also: Resource::isReloadable for resource is reloadable.

References Ogre::Resource::LF_DEFAULT, and Ogre::Resource::LF_INCLUDE_NON_RELOADABLE.

◆ unloadAll() [2/2]

virtual void Ogre::ResourceManager::unloadAll ( Resource::LoadingFlags flags )

virtualinherited

Unloads all resources.

Remarks: Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

See also: ResourceGroupManager for unloading of resource groups.

Parameters

flags Allow to restrict processing to only reloadable and/or unreferenced resources.

See also: Resource::LoadingFlags for additional information.

◆ reloadAll() [1/2]

void Ogre::ResourceManager::reloadAll ( bool reloadableOnly = true )

inlineinherited

Caused all currently loaded resources to be reloaded.

Remarks: All resources currently being held in this manager which are also marked as currently loaded will be unloaded, then loaded again.

Parameters

reloadableOnly If true (the default), only reload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't loaded again. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later.

See also: Resource::isReloadable for resource is reloadable.

References Ogre::Resource::LF_DEFAULT, and Ogre::Resource::LF_INCLUDE_NON_RELOADABLE.

◆ reloadAll() [2/2]

virtual void Ogre::ResourceManager::reloadAll ( Resource::LoadingFlags flags )

virtualinherited

Caused all currently loaded resources to be reloaded.

Remarks: All resources currently being held in this manager which are also marked as currently loaded will be unloaded, then loaded again.

Parameters

flags Allow to restrict processing to only reloadable and/or unreferenced resources. Additionally, reloading could be done with preserving some selected resource states that could be used elsewhere.

See also: Resource::LoadingFlags for additional information.

◆ unloadUnreferencedResources()

void Ogre::ResourceManager::unloadUnreferencedResources ( bool reloadableOnly = true )

inlineinherited

Unload all resources which are not referenced by any other object.

Remarks: This method behaves like unloadAll, except that it only unloads resources which are not in use, ie not referenced by other objects. This allows you to free up some memory selectively whilst still keeping the group around (and the resources present, just not using much memory).

: Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, unload or reload that resource will cause dangerous pointer access. Use this function instead of unloadAll allows you avoid fail in those situations.

Parameters

reloadableOnly If true (the default), only unloads resources which can be subsequently automatically reloaded.

References Ogre::Resource::LF_ONLY_UNREFERENCED, and Ogre::Resource::LF_ONLY_UNREFERENCED_INCLUDE_NON_RELOADABLE.

◆ reloadUnreferencedResources()

void Ogre::ResourceManager::reloadUnreferencedResources ( bool reloadableOnly = true )

inlineinherited

Caused all currently loaded but not referenced by any other object resources to be reloaded.

Remarks: This method behaves like reloadAll, except that it only reloads resources which are not in use, i.e. not referenced by other objects.

: Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, unload or reload that resource will cause dangerous pointer access. Use this function instead of reloadAll allows you avoid fail in those situations.

Parameters

reloadableOnly If true (the default), only reloads resources which can be subsequently automatically reloaded.

◆ remove() [1/3]

void Ogre::ResourceManager::remove ( const ResourcePtr & r )

inherited

Remove a single resource.

Remarks: Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.

Note: The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

◆ remove() [2/3]

void Ogre::ResourceManager::remove	(	const String &	name,
		const String &	group = `RGN_DEFAULT`
	)

inherited

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ remove() [3/3]

void Ogre::ResourceManager::remove ( ResourceHandle handle )

inherited

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ removeAll()

virtual void Ogre::ResourceManager::removeAll ( void )

virtualinherited

Removes all resources.

Note: The word 'Destroy' is not used here, since if any other pointers are referring to these resources, they will persist until they have been finished with; however to all intents and purposes the resources no longer exist and will get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

Reimplemented in Ogre::CompositorManager.

◆ removeUnreferencedResources()

virtual void Ogre::ResourceManager::removeUnreferencedResources ( bool reloadableOnly = true )

virtualinherited

Remove all resources which are not referenced by any other object.

Remarks: This method behaves like removeAll, except that it only removes resources which are not in use, ie not referenced by other objects. This allows you to free up some memory selectively whilst still keeping the group around (and the resources present, just not using much memory).

: Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, remove or reload that resource will cause dangerous pointer access. Use this function instead of removeAll allows you avoid fail in those situations.

Parameters

reloadableOnly If true (the default), only removes resources which can be subsequently automatically reloaded.

◆ getByHandle()

virtual ResourcePtr Ogre::ResourceManager::getByHandle ( ResourceHandle handle )

virtualinherited

Retrieves a pointer to a resource by handle, or null if the resource does not exist.

◆ resourceExists() [1/2]

bool Ogre::ResourceManager::resourceExists	(	const String &	name,
		const String &	group = `RGN_DEFAULT`
	)

inlineinherited

Returns whether the named resource exists in this manager.

◆ resourceExists() [2/2]

bool Ogre::ResourceManager::resourceExists ( ResourceHandle handle )

inlineinherited

Returns whether a resource with the given handle exists in this manager.

◆ _notifyResourceTouched()

virtual void Ogre::ResourceManager::_notifyResourceTouched ( Resource * res )

virtualinherited

Notify this manager that a resource which it manages has been 'touched', i.e.

used.

◆ _notifyResourceLoaded()

virtual void Ogre::ResourceManager::_notifyResourceLoaded ( Resource * res )

virtualinherited

Notify this manager that a resource which it manages has been loaded.

◆ _notifyResourceUnloaded()

virtual void Ogre::ResourceManager::_notifyResourceUnloaded ( Resource * res )

virtualinherited

Notify this manager that a resource which it manages has been unloaded.

◆ prepare()

ResourcePtr Ogre::ResourceManager::prepare	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	loadParams = `0`,
		bool	backgroundThread = `false`
	)

inherited

Generic prepare method, used to create a Resource specific to this ResourceManager without using one of the specialised 'prepare' methods (containing per-Resource-type parameters).

Parameters

name	The name of the Resource
group	The resource group to which this resource will belong
isManual	Is the resource to be manually loaded? If so, you should provide a value for the loader parameter
loader	The manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter
loadParams	Optional pointer to a list of name/value pairs containing loading parameters for this type of resource.
backgroundThread	Optional boolean which lets the load routine know if it is being run on the background resource loading thread

◆ getScriptPatterns()

const StringVector& Ogre::ResourceManager::getScriptPatterns ( void ) const

inlinevirtualinherited

Gets the file patterns which should be used to find scripts for this ResourceManager.

Remarks: Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).

: This method lets you determine the file pattern which will be used to identify scripts intended for this manager.

Returns: A list of file patterns, in the order they should be searched in.

See also: parseScript

Implements Ogre::ScriptLoader.

◆ parseScript()

void Ogre::ResourceManager::parseScript	(	DataStreamPtr &	stream,
		const String &	groupName
	)

inlinevirtualinherited

Parse the definition of a set of resources from a script file.

Remarks: Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).

Parameters

stream	Weak reference to a data stream which is the source of the script
groupName	The name of the resource group that resources which are parsed are to become a member of. If this group is loaded or unloaded, then the resources discovered in this script will be loaded / unloaded with it.

Implements Ogre::ScriptLoader.

Reimplemented in Ogre::FontManager.

◆ getLoadingOrder()

Real Ogre::ResourceManager::getLoadingOrder ( void ) const

inlinevirtualinherited

Gets the relative loading order of resources of this type.

Remarks: There are dependencies between some kinds of resource in terms of loading order, and this value enumerates that. Higher values load later during bulk loading tasks.

Implements Ogre::ScriptLoader.

◆ getResourceType()

const String& Ogre::ResourceManager::getResourceType ( void ) const

inlineinherited

Gets a string identifying the type of resource this manager handles.

◆ setVerbose()

void Ogre::ResourceManager::setVerbose ( bool v )

inlineinherited

Sets whether this manager and its resources habitually produce log output.

◆ getVerbose()

bool Ogre::ResourceManager::getVerbose ( void )

inlineinherited

Gets whether this manager and its resources habitually produce log output.

◆ getResourcePool()

ResourcePool* Ogre::ResourceManager::getResourcePool ( const String & name )

inherited

Create a resource pool, or reuse one that already exists.

◆ destroyResourcePool() [1/2]

void Ogre::ResourceManager::destroyResourcePool ( ResourcePool * pool )

inherited

Destroy a resource pool.

◆ destroyResourcePool() [2/2]

void Ogre::ResourceManager::destroyResourcePool ( const String & name )

inherited

Destroy a resource pool.

◆ destroyAllResourcePools()

void Ogre::ResourceManager::destroyAllResourcePools ( )

inherited

destroy all pools

◆ getResourceIterator()

ResourceMapIterator Ogre::ResourceManager::getResourceIterator ( void )

inlineinherited

Returns an iterator over all resources in this manager.

Note: Use of this iterator is NOT thread safe!
