Member Function Documentation

◆ getGroupExecutionOrder()

int Ogre::RTShader::FunctionAtom::getGroupExecutionOrder ( ) const

Get the group execution order of this function atom.

◆ getOperandList()

OperandVector & Ogre::RTShader::FunctionAtom::getOperandList ( )

inline

Get a list of parameters this function invocation will use in the function call as arguments.

◆ pushOperand()

void Ogre::RTShader::FunctionAtom::pushOperand	(	ParameterPtr	parameter,
		Operand::OpSemantic	opSemantic,
		Operand::OpMask	opMask = `Operand::OPM_ALL`,
		int	indirectionLevel = `0`
	)

Push a new operand (on the end) to the function.

Parameters

parameter	A function parameter.
opSemantic	The in/out semantic of the parameter.
opMask	The field mask of the parameter.
indirectionLevel	The level of nesting inside brackets

◆ setOperands()

void Ogre::RTShader::FunctionAtom::setOperands ( const OperandVector & ops )

◆ writeSourceCode()

virtual void Ogre::RTShader::FunctionAtom::writeSourceCode	(	std::ostream &	os,
		const String &	targetLanguage
	)		const

pure virtual

Abstract method that writes a source code to the given output stream in the target shader language.

Implemented in Ogre::RTShader::FunctionInvocation, Ogre::RTShader::AssignmentAtom, Ogre::RTShader::SampleTextureAtom, Ogre::RTShader::BinaryOpAtom, and Ogre::RTShader::BuiltinFunctionAtom.
