Member Function Documentation
| void Resources::TexturePoolMapperScheduler::SetMapper | ( | const Ptr< StreamingResourceMapper > & | mapper | ) | [virtual] |
sets the ResourceMapper and the PoolResourceMapper (downcasts the ResourceMapper)
This stores a downcasted copy of the Ptr as a separate PoolResourceMapper so we don't need to cast it frequently OnFrame.
Reimplemented from Resources::ResourceScheduler.
| bool Resources::TexturePoolMapperScheduler::OnRequestManagedResource | ( | const Ptr< ManagedResource > & | managedResource, | |
| const ResourceRequestInfo * | requestInfo | |||
| ) | [virtual] |
tries to load a resource and returns true if request was successful
Looks up a fitting pool and a free slot in this pool is looked up. If there is a free slot available the slot's Resource is set to requested Resource and a new LoadingResource-entry is sorted into the loadingQueue. If NO free slot is currently available false is returned. If NO free pool is found an error is thrown as this must not occur as each requested resource should have a valid entry in the resource dictionary.
Reimplemented from Resources::ResourceScheduler.
| void Resources::ResourceScheduler::CleanUpLoadingQueue | ( | ) | [virtual, inherited] |
cleans the loading queue
As a very basic this method cleans up loadingQueue and removes loaded Resources. If loading failed or canceled StreamingResourceMapper::ResourceLoadException is called appropriate Resource. Overload this method in subclasses to perform additional clean-ups of the loadingQueue like kicking out requests which are out of date.
| 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.
Field Documentation
points to same target as ResourceScheduler::mapper but we do need this as we want to have some PoolResourceMapper specific functionalities
