pure virtual

Returns

if an arrays, how long is it

virtual RixShaderBaseType RixShaderParameter::BaseType ( void  ) const

pure virtual

Returns

the data type

virtual const float* RixShaderParameter::DefaultF ( void  ) const

pure virtual

Returns

if an floating point type then the default value

virtual const int* RixShaderParameter::DefaultI ( void  ) const

pure virtual

Returns

if an integral type then the default value

virtual const char** RixShaderParameter::DefaultS ( void  ) const

pure virtual

Returns

if an string type then the default value

virtual int RixShaderParameter::DefaultSize ( void  ) const

pure virtual

Returns

Default size for array parameters

virtual bool RixShaderParameter::IsArray ( void  ) const

pure virtual

Returns

parameters might be arrays.

virtual bool RixShaderParameter::IsOutput ( void  ) const

pure virtual

Returns

parameters might be outputs

virtual bool RixShaderParameter::IsStruct ( void  ) const

pure virtual

Returns

parameters might be structs.

virtual const RixShaderParameter* const* RixShaderParameter::MetaData ( void  ) const

pure virtual

This pointer is valid until this parameter is deleted.

Returns

the fields of the struct as parameters.

virtual int RixShaderParameter::MetaDataSize ( void  ) const

pure virtual

Call Metadata() first before calling this.

Returns

the count of fields

virtual const char* RixShaderParameter::Name ( void  ) const

pure virtual

Returns

the parameter's name

virtual const char* RixShaderParameter::StructName ( void  ) const

pure virtual

Returns

the parameter's name if it is a struct

virtual RixShaderParameterType RixShaderParameter::Type ( void  ) const

pure virtual

Returns

the type

virtual RixShaderVectorSemantics RixShaderParameter::VectorSemantics ( void  ) const

pure virtual

Returns

if a vector, what kind is it
