class IShaderProgram;

The IShaderProgram interface represents a set of shader programs for graphics rendering. Code for individual shader stages are loaded into this object and compiled. Once this process is complete, the shader program is able to be attached to an IProgramNode in the render tree. After compilation, it is also possible to retrieve IDs for the various external elements that can be provided to the shader programs, such as vertex attributes and constant buffers.

Initialization methods

	Name	Description
	Delete	Schedules the object for deletion. After calling this method, the object will be destroyed after the current frame completes drawing.

Code format methods

	Name	Description
	IsCodeFormatSupported	Reports whether the specified code format is supported by the target renderer
	PreferredCodeFormat	Returns the preferred code format for the target renderer

Compilation methods

	Name	Description
	ConfigureShaderTarget	Sets optional configuration settings for the renderer to use when loading and compiling shader code.
	LoadShaderStage	Loads in code for the specified shader stage. The code is not compiled or validated until CompileProgram is called.
	CompileProgram	Attempts to compile the code supplied by the LoadShaderStage method. Prior to calling this method, the shader program cannot be bound to an IProgramNode, and no information about the shader program can be queried.

Shader input methods

	Name	Description
	VertexAttributeExists	Returns true if the specified vertex attribute exists
	StateValueExists	Returns true if the specified global state value exists
	TextureExists	Returns true if the specified texture resource exists
	SamplerExists	Returns true if the specified separate texture sampler
	StateBufferExists	Returns true if the specified state buffer exists
	ResourceArrayExists	Returns true if the specified resource array exists
	GetVertexAttributeId	Retrieves the ID of the specified vertex attribute, or VertexAttributeId::Null if the attribute could not be found.
	GetStateValueId	Retrieves the ID of the specified shader state variable, or StateValueId::Null if the variable could not be found.
	GetTextureId	Retrieves the ID of the specified texture input, or TextureId::Null if the texture input could not be found.
	GetSamplerId	Retrieves the ID of the specified separate texture sampler, or SamplerId::Null if the sampler could not be found.
	GetStateBufferId	Retrieves the ID of the specified state buffer, or StateBufferId::Null if the buffer could not be found.
	GetResourceArrayId	Retrieves the ID of the specified resource array (ITexelArray or IDataArray), or ResourceArrayId::Null if the resource could not be found.

State buffer methods

	Name	Description
	LoadStateBufferLayoutFromShader	Attempts to load the layout of the specified state buffer into an IStateBufferLayout
