| bool Direct3D9::D3D9MemoryIndexBufferLoader::OnLoadRequested | ( | ) | [virtual, inherited] |
called by resource when a load is requested
This will create a D3D9 IndexBuffer using the data provided by our Setup() method and set our resource object (which must be a D3D9IndexBuffer object). The data pointer provided to Setup() will be invalidated inside OnLoadRequested(). Usage will be set to UsageImmutable and Access to AccessNone.
Reimplemented from Resources::ResourceLoader.
| void Base::MemoryIndexBufferLoaderBase::Setup | ( | CoreGraphics::IndexType::Code | indexType, | |
| SizeT | num, | |||
| void * | ptr, | |||
| SizeT | numBytes | |||
| ) | [inherited] |
setup index buffer data, must remain valid until OnLoadRequested() is called!
Setup all information needed to initialize the IndexBuffer resource. The data must remain valid until OnLoadRequested() is called (which will invaliate the data).
| void Base::MemoryIndexBufferLoaderBase::Setup | ( | CoreGraphics::IndexType::Code | indexType, | |
| SizeT | num, | |||
| SizeT | numBytes, | |||
| CoreGraphics::IndexBuffer::Usage | usage, | |||
| CoreGraphics::IndexBuffer::Access | access | |||
| ) | [inherited] |
setup a empty index buffer
Setup all information needed to initialize a empty IndexBuffer resource.
| void Base::MemoryIndexBufferLoaderBase::Setup | ( | CoreGraphics::IndexType::Code | type, | |
| SizeT | num, | |||
| void * | ptr, | |||
| SizeT | numBytes, | |||
| CoreGraphics::IndexBuffer::Usage | usage, | |||
| CoreGraphics::IndexBuffer::Access | access | |||
| ) | [inherited] |
setup index buffer data, must remain valid until OnLoadRequested() is called!
Setup all information needed to initialize a IndexBuffer resource.
| bool Resources::ResourceLoader::CanLoadAsync | ( | ) | const [virtual, inherited] |
return true if asynchronous loading is supported
This method should be overriden in a subclass and indicates whether the resource loader supports asynchronous resource loading. If asynchronous loading is requested, the OnLoadRequested() method will return immediately and the Resource object will be put into Pending state. Afterwards, the Resource object needs to poll the ResourceLoader using the OnPending method, which will eventually setup the Resource object.
Reimplemented in Direct3D9::D3D9StreamShaderLoader, Direct3D9::D3D9StreamTextureLoader, CoreGraphics::StreamAnimationLoader, CoreGraphics::StreamMeshLoader, and Models::StreamModelLoader.
| void Resources::ResourceLoader::OnLoadCancelled | ( | ) | [virtual, inherited] |
called by resource to cancel a pending load
This method is called by our Resource object if a pending asynchronous load should be cancelled.
Reimplemented in Direct3D9::D3D9StreamTextureLoader, CoreGraphics::StreamAnimationLoader, CoreGraphics::StreamMeshLoader, and Models::StreamModelLoader.
| bool Resources::ResourceLoader::OnPending | ( | ) | [virtual, inherited] |
call frequently while after OnLoadRequested() to put Resource into loaded state
This method should be called at some time after OnLoadRequested() as long as the ResourceLoader is in the Pending state. This will check whether the asynchronous loader job has finished, and if yes, setup the Resource object, bringing it from the Pending into the Loaded state. If something goes wrong, the ResourceLoader will go into the Failed state. If the outstanding loader job isn't finished yet, the ResourceLoader should remain in Pending state, and the method should return false. Otherwise the Resource should be initialized, and the method should return true.
Reimplemented in Direct3D9::D3D9StreamTextureLoader, CoreGraphics::StreamAnimationLoader, CoreGraphics::StreamMeshLoader, and Models::StreamModelLoader.
| int Core::RefCounted::GetRefCount | ( | ) | const [inline, inherited] |
get the current refcount
Return the current refcount of the object.
| void Core::RefCounted::AddRef | ( | ) | [inline, inherited] |
increment refcount by one
Increment the refcount of the object.
| void Core::RefCounted::Release | ( | ) | [inline, inherited] |
decrement refcount and destroy object if refcount is zero
Decrement the refcount and destroy object if refcount is zero.
| const Util::String & Core::RefCounted::GetClassName | ( | ) | const [inline, inherited] |
get the class name
Get the class name of the object.
| Util::FourCC Core::RefCounted::GetClassFourCC | ( | ) | const [inline, inherited] |
get the class FourCC code
Get the class FourCC of the object.
| void Core::RefCounted::DumpRefCountingLeaks | ( | ) | [static, inherited] |
dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)
This method should be called as the very last before an application exits.
