Base::ShaderInstanceBase Class Reference
#include <shaderinstancebase.h>
Detailed Description
A shader instance object is created from a shader and contains a local copy of the original shader state which can be modified through ShaderVariable objects. Shader instance objects are created directly through the shader server.(C) 2007 Radon Labs GmbH

Member Function Documentation
| void Base::ShaderInstanceBase::Discard | ( | ) |
discard the shader instance, must be called when instance no longer needed
This method must be called when the object is no longer needed for proper cleanup.
| void Base::ShaderInstanceBase::Setup | ( | const Ptr< CoreGraphics::Shader > & | origShader | ) | [protected, virtual] |
setup the shader instance from its original shader object
Override this method in an API-specific subclass to setup the shader instance, and call the parent class for proper setup.
Reimplemented in Direct3D9::D3D9ShaderInstance.
| void Base::ShaderInstanceBase::Cleanup | ( | ) | [protected, virtual] |
cleanup the shader instance
Override this method in an API-specific subclass to undo the setup in OnInstantiate(), then call parent class to finalize the cleanup.
Reimplemented in Direct3D9::D3D9ShaderInstance.
| 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.
