Constructor & Destructor Documentation

Operand() [1/2]

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.
indirectionLevel

Operand() [2/2]

Ogre::RTShader::Operand::Operand

(

const Operand &

rhs

)

Copy constructor.

~Operand()

Ogre::RTShader::Operand::~Operand

(

)

Class destructor.

Member Function Documentation

operator=()

Operand& Ogre::RTShader::Operand::operator=

(

const Operand &

rhs

)

Copy the given Operand to this Operand.

Parameters

rhs	The other Operand to copy to this state.

getParameter()

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

inline

Returns the parameter object as weak reference.

hasFreeFields()

bool Ogre::RTShader::Operand::hasFreeFields ( ) const

inline

Returns true if not all fields used.

(usage is described through semantic)

getMask()

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

inline

Returns the mask bitfield.

x()

Operand& Ogre::RTShader::Operand::x ( )

inline

y()

Operand& Ogre::RTShader::Operand::y ( )

inline

z()

Operand& Ogre::RTShader::Operand::z ( )

inline

w()

Operand& Ogre::RTShader::Operand::w ( )

inline

xy()

Operand& Ogre::RTShader::Operand::xy ( )

inline

xyz()

Operand& Ogre::RTShader::Operand::xyz ( )

inline

mask()

Operand& Ogre::RTShader::Operand::mask ( int  opMask )

inline

setMaskToParamType()

void Ogre::RTShader::Operand::setMaskToParamType

(

)

automatically set swizzle to match parameter arity

getSemantic()

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

inline

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

getIndirectionLevel()

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

inline

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]].

toString()

String Ogre::RTShader::Operand::toString

(

)

const

Returns the parameter name and the usage mask like this 'color.xyz'.

getMaskAsString()

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

static

Returns the given mask as string representation.

getFloatCount()

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

static

Return the float count of the given mask.

getGpuConstantType()

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

static

Return the gpu constant type of the given mask.
