Operand() [2/2]

Ogre::RTShader::Operand::Operand

(

const Operand &

rhs

)

Copy constructor.

References Operand().

~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.

References Operand().

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)

References OPM_ALL.

getMask()

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

inline

Returns the mask bitfield.

x()

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

inline

References Operand(), mask(), and OPM_X.

y()

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

inline

References Operand(), mask(), and OPM_Y.

z()

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

inline

References Operand(), mask(), and OPM_Z.

w()

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

inline

References Operand(), mask(), and OPM_W.

xy()

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

inline

References Operand(), mask(), and OPM_XY.

xyz()

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

inline

References Operand(), mask(), and OPM_XYZ.

mask()

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

inline

References Operand().

Referenced by getFloatCount(), w(), x(), xy(), xyz(), y(), and z().

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]].

write()

void Ogre::RTShader::Operand::write

(

std::ostream &

os

)

const

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

getFloatCount()

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

static

Return the float count of the given mask.
