Resources::Resource Class Reference
#include <resource.h>
Detailed Description
Base class for shareable resources. Resources contain some sort of data which can be loaded and saved by specialized ResourceLoaders and ResourceSavers.: before destroying a Resource object, the Loader and Saver objects must be manually set to null to resolve a cyclic pointer dependency. The SharedResourceServer will take care of this automatically, but when creating resources directly, this must be taken care of!

Member Function Documentation
| Resource::State Resources::Resource::Load | ( | ) | [virtual] |
load the resource
This loads the resource through the attached resource loader. Depending on the resource loader, the resource may happen synchronously or asynchronously. If the resource is loaded asynchronously, the IsPending() method will return true as long as the load is in progress, and IsLoaded() will become true when the loading process has finished. If the load has failed, IsPending() will switch to false and IsLoaded() will not be true.
| void Resources::Resource::Unload | ( | ) | [virtual] |
unload the resource, or cancel the pending load
This will unload the resource. Only call the method when IsLoaded() return true. To cancel a pending asynchronous loading process, call the CancelPendingLoad() method.
Reimplemented in Base::MeshBase, Base::VertexBufferBase, CoreGraphics::CPUIndexBuffer, CoreGraphics::CPUVertexBuffer, Direct3D9::D3D9IndexBuffer, Direct3D9::D3D9Shader, Direct3D9::D3D9Texture, Direct3D9::D3D9VertexBuffer, and Models::Model.
| bool Resources::Resource::Save | ( | ) | [virtual] |
save the resource
This will save the resource. A resource saver must be attached to the resource and the resource must be loaded for the method to succeed. Saving will always be performed synchronously.
| 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.
