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
parameterA function parameter.
opSemanticThe in/out semantic of the parameter.
opMaskThe field mask of the parameter.

◆ Operand() [2/2]

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

Copy constructor.

◆ ~Operand()

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

Class destructor.

Member Function Documentation

◆ 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.

◆ 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]].

◆ getMask()

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

Returns the mask bitfield.

◆ getMaskAsString()

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

Returns the given mask as string representation.

◆ getParameter()

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

Returns the parameter object as weak reference.

◆ getSemantic()

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

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

◆ hasFreeFields()

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

Returns true if not all fields used.

(usage is described through semantic)
