Constructor & Destructor Documentation

Ogre::RTShader::Operand::Operand	(	ParameterPtr	parameter,
		Operand::OpSemantic	opSemantic,
		int	opMask = `Operand::OPM_ALL`,
		ushort	indirectionLevel = `0`
	)

Class constructor.

Parameters:

parameter	A function parameter.
opSemantic	The in/out semantic of the parameter.
opMask	The field mask of the parameter.

Ogre::RTShader::Operand::Operand ( const Operand & rhs )

Copy constructor.

Ogre::RTShader::Operand::~Operand ( )

Class destructor.

Member Function Documentation

static int Ogre::RTShader::Operand::getFloatCount ( int mask ) [static]

Return the float count of the given mask.

static GpuConstantType Ogre::RTShader::Operand::getGpuConstantType ( int mask ) [static]

Return the gpu constant type of the given mask.

ushort Ogre::RTShader::Operand::getIndirectionLevel ( ) const

Returns the level of indirection.

The greater the indirection level the more the parameter needs to be nested in brackets. For example given 4 parameters x1...x4 with the indirections levels 0,1,1,2 respectively. The parameters should form the following string: x1[x2][x3[x4]].

Definition at line 151 of file OgreShaderFunctionAtom.h.

int Ogre::RTShader::Operand::getMask ( ) const

Returns the mask bitfield.

Definition at line 141 of file OgreShaderFunctionAtom.h.

static String Ogre::RTShader::Operand::getMaskAsString ( int mask ) [static]

Returns the given mask as string representation.

const ParameterPtr& Ogre::RTShader::Operand::getParameter ( ) const

Returns the parameter object as weak reference.

Definition at line 135 of file OgreShaderFunctionAtom.h.

OpSemantic Ogre::RTShader::Operand::getSemantic ( ) const

Returns the operand semantic (do we read/write or both with the parameter).
