Detailed Description

An extension of PlotExpression defining a unary operation.

This tracks the child and manages binding, but derivations are required to implement the sample() function.

Constructor & Destructor Documentation

PlotUnaryOperator::PlotUnaryOperator ( PlotExpression *  operand )

inline

Create a binary operator on the given left and right expressions.

Parameters

operand

The child expression.

Member Function Documentation

bool PlotUnaryOperator::explicitTime ( ) const

overridevirtual

Is the generated expression sensitive to changes in the time domain?

Returns

True if the child returns true.

Reimplemented from PlotExpression.

const PlotExpression* PlotUnaryOperator::operand ( ) const

inline

Get the operand expression.

Returns

The operand.

Referenced by PlotUnaryOperatorT< std::negate< double > >::clone(), PlotUnaryOperatorT< std::negate< double > >::sample(), and setOperand().

void PlotUnaryOperator::setOperand ( PlotExpression *  operand )

inline

Set the operand expression.

Does not release the existing expression.

Parameters

operand

The new operand.

References operand().
