ID3DXConstantTable interface

The ID3DXConstantTable interface is used to access the constant table. This table contains the variables that are used by high-level language shaders and effects.

Members

The ID3DXConstantTable interface inherits from the IUnknown interface. ID3DXConstantTable also has these types of members:

• Methods

Methods

The ID3DXConstantTable interface has these methods.

Method	Description
GetBufferPointer	Gets a pointer to the buffer that contains the constant table.
GetBufferSize	Gets the buffer size of the constant table.
GetConstant	Gets a constant by looking up its index.
GetConstantByName	Gets a constant by looking up its name.
GetConstantDesc	Gets a pointer to an array of constant descriptions in the constant table.
GetConstantElement	Gets a constant from an array of constants. An array is made up of elements.
GetDesc	Gets a description of the constant table.
GetSamplerIndex	Returns the sampler index.
SetBool	Sets a Boolean value.
SetBoolArray	Sets an array of Boolean values.
SetDefaults	Sets the constants to their default values. The default values are declared in the variable declarations in the shader.
SetFloat	Sets a floating-point number.
SetFloatArray	Sets an array of floating-point numbers.
SetInt	Sets an integer value.
SetIntArray	Sets an array of integers.
SetMatrix	Sets a nontransposed matrix.
SetMatrixArray	Sets an array of nontransposed matrices.
SetMatrixPointerArray	Sets an array of pointers to nontransposed matrices.
SetMatrixTranspose	Sets a transposed matrix.
SetMatrixTransposeArray	Sets an array of transposed matrices.
SetMatrixTransposePointerArray	Sets an array of pointers to transposed matrices.
SetValue	Sets the contents of the buffer to the constant table.
SetVector	Sets a 4D vector.
SetVectorArray	Sets an array of 4D vectors.

 

Remarks

The LPD3DXCONSTANTTABLE type is defined as a pointer to the ID3DXConstantTable interface.

typedef interface ID3DXConstantTable ID3DXConstantTable;
typedef interface ID3DXConstantTable *LPD3DXCONSTANTTABLE;
