Inheritance diagram for Base::ShaderVariableInstanceBase:

Core::RefCounted CoreGraphics::ShaderVariableInstance


Detailed Description

A ShaderVariableInstance associates a value with a ShaderVariable and can apply that value at any time to the ShaderVariable. Setting the value on a ShaderVariableInstance will just store the value but not change the actual ShaderVariable. Only calling Apply() will set the stored value on the ShaderVariable. ShaderVariableInstance objects are used to manage per-instance state when rendering ModelNodeInstances.

Member Function Documentation

void Base::ShaderVariableInstanceBase::Apply (  ) 

apply local value to shader variable

Todo:
: hmm, the dynamic type switch is sort of lame...

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.
