Detailed Description

Handles the management of mesh resources.

Remarks: This class deals with the runtime management of mesh data; like other resource managers it handles the creation of resources (in this case mesh data), working within a fixed memory budget.; Ogre loads model files from it's own proprietary format called .mesh. This is because having a single file format is better for runtime performance, and we also have control over pre-processed data (such as collision boxes, LOD reductions etc).

Member Function Documentation

◆ _initialise()

void Ogre::MeshManager::_initialise ( void )

Initialises the manager, only to be called by OGRE internally.

◆ getByName()

MeshPtr Ogre::MeshManager::getByName	(	const String &	name,
		const String &	groupName = `RGN_DEFAULT`
	)

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

	)

Create a new mesh.

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.

		const String &	groupName,
		HardwareBuffer::Usage	vertexBufferUsage = `HardwareBuffer::HBU_STATIC_WRITE_ONLY`,
		HardwareBuffer::Usage	indexBufferUsage = `HardwareBuffer::HBU_STATIC_WRITE_ONLY`,
		bool	vertexBufferShadowed = `false`,
		bool	indexBufferShadowed = `false`
	)

Loads a mesh from a file, making it immediately available for use.

This does the IO in advance of the call to load().

Note: If the model has already been created (prepared or loaded), the existing instance will be returned.

Parameters

filename	The name of the .mesh file

◆ createManual()

MeshPtr Ogre::MeshManager::createManual	(	const String &	name,
		const String &	groupName,
		ManualResourceLoader *	loader = `0`
	)

Creates a new Mesh specifically for manual definition rather than loading from an object file.

Note that once you've defined your mesh, you must call Mesh::_setBounds in order to define the bounds of your mesh. In previous versions of OGRE could auto-compute that, but OGRE's support of write-only vertex buffers makes this no longer appropriate.

Parameters

name	The name to give the new mesh
groupName	The name of the resource group to assign the mesh to
loader	ManualResourceLoader which will be called to load this mesh when the time comes. It is recommended that you populate this field in order that the mesh can be rebuilt should the need arise

		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

inlineinherited

Gets the current memory usage, in bytes.

◆ unload() [1/2]

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

inherited

Unloads a single resource by name.

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.

◆ 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
