Member Function Documentation

const string& gridripper::math::expr::StkFunc::getOpName

(

)

const [inline, virtual]

Gets the function name.

Implements gridripper::math::expr::StkOp.

int gridripper::math::expr::StkFunc::getArgCount

(

)

const [inline, virtual]

Gets the number of arguments.

Implements gridripper::math::expr::StkOp.

int gridripper::math::expr::StkFunc::getStackIncrement

(

)

const [inline, virtual]

The stack increment is 1 - (number of arguments) for functions.

Implements gridripper::math::expr::StkOp.

virtual bool gridripper::math::expr::StkFunc::dependsOn

(

Reimplemented in gridripper::math::expr::Expr.

virtual void gridripper::math::expr::StkFunc::evalStack

(

GReal_t *&

p

)

const [pure virtual]

Evaluates the stack.

Parameters:

p

the stack pointer

Implements gridripper::math::expr::StkOp.

Implemented in gridripper::math::expr::Expr, gridripper::math::expr::StkArg, gridripper::math::expr::StkConst, and gridripper::math::expr::StkVar.

virtual string gridripper::math::expr::StkFunc::getClassName

(

)

const [inline, virtual]

Gets the class name.

Returns:

the class name

Implements gridripper::math::expr::StkOp.

Reimplemented in gridripper::math::expr::Expr, gridripper::math::expr::StkArg, gridripper::math::expr::StkConst, and gridripper::math::expr::StkVar.
