Public Attributes | |
OGRE_AUTO_MUTEX | |
Abstract class representing a loadable resource (e.g.
textures, sounds etc)
Enum that allow to choose subset of unloaded/reloaded resources and to adjust reloading behavior.
Ogre::Resource::Resource | ( | ResourceManager * | creator, |
const String & | name, | ||
ResourceHandle | handle, | ||
const String & | group, | ||
bool | isManual = false , |
||
ManualResourceLoader * | loader = 0 |
||
) |
Standard constructor.
creator | Pointer to the ResourceManager that is creating this resource |
name | The unique name of the resource |
group | The name of the resource group to which this resource belongs |
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 ManualResourceLoader 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 ManualResourceLoader instance is strongly recommended. |
|
virtual |
Virtual destructor.
Shouldn't need to be overloaded, as the resource deallocation code should reside in unload()
|

Manually mark the state of this resource as having been changed.
|

wasBackgroundLoaded | Whether this was a background loaded event |
|
virtual |
Firing of preparing complete event.
wasBackgroundLoaded | Whether this was a background loaded event |
|
virtual |
Firing of unloading complete event.

a script file name.

|
inlinevirtual |
Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.
Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

Returns true if the Resource has been loaded, false otherwise.

Prepares the resource for load, if it is not already.
One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.
backgroundThread | Whether this is occurring in a background thread |

virtual |
Reloads the resource, if it is already loaded.
