IParameterManager Class Reference

#include <RTMax.h>

Class Description

A data management class for accessing data required for displaying real time effects.

An instance of this class is maintained by the DirectX 9 Shader material and is passed into the IEffectParser::PreRender() method. This allows the Effect Parsers to format the data accordingly based on the runtime active for the shader

Member Function Documentation

virtual int GetNumberOfParams ( )

pure virtual

The total number of parameters maintained by the manager.

Returns

The number of parameters

virtual MaxSemantics GetParamSemantics ( int  index )

pure virtual

The semantic for the parameter.

This will be the semantic usage found in the shader file when it is parsed by the system

Parameters

index

The index of the parameter to query

Returns

An item from MaxSemantics representing the semantic found in the file

virtual const MCHAR* GetParamName ( int  index )

pure virtual

Retireve the name of the parameter.

This will be the name of the parameter found in the shader file

Parameters

index

The index of the parameter to query

Returns

A string containing the name

virtual bool GetParamData ( LPVOID  data, int  index  )

pure virtual

Access to the actual data stored by the manager.

This is the main access point for data retrieval. It is the calling code's responsibility to make sure there is enough space allocated to receive the data. This can be determined by calling GetParamType, which will return the data type. If it is a kPtype_Matrix, then internally this is stored as an 4x4 float array

Parameters

data	A pointer to a buffer to receive the data
index	THe index of the parameter to query

Returns

True/False depending if the parameter was found, and the data copied correctly

virtual bool GetParamData ( LPVOID  data, const MCHAR *  paramName  )

pure virtual

Access to the actual data stored by the manager.

This is an access point for data retrieval. It is the calling code's responsibility to make sure there is enough space allocated to receive the data. This can be determined by calling GetParamType, which will return the data type. If it is a kPtype_Matrix, then internally this is stored as an 4x4 float array

Parameters

data	A pointer to a buffer to receive the data
paramName	The name of the parameter to query

Returns

True/False depending if the parameter was found, and the data copied correctly

virtual int GetParamType ( int  index )

pure virtual

Access the data type of the parameter.

This method returns the type of parameter. This will be one of the enumerated types define in IParameterManager, kPType_Matrix etc..

Parameters

index

The index of the parameter to query

Returns

The parameter type

virtual int GetParamType ( const MCHAR *  parmName )

pure virtual

Access the data type of the parameter.

This method returns the type of parameter. This will be one of the enumerated types define in IParameterManager, kPType_Matrix etc..

Parameters

parmName

The name of the parameter to query

Returns

The parameter type

virtual int GetParamSize ( int  index )

pure virtual

Access the data size of the parameter (mainly designed for kPType_Struct type)

This method returns the size of the parameter, in D3DXVECTOR4 (upper rounded to), or number of textures.

Parameters

index

The index of the parameter to query

Returns

The parameter size
