Detailed Description

An extension of PlotExpression defining a binary operation.

This is essentially a binary in the expression tree.

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

Constructor & Destructor Documentation

PlotBinaryOperator::PlotBinaryOperator ( PlotExpression *  left, PlotExpression *  right  )

inline

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

Parameters

left	The left expression.
right	The right expression.

Member Function Documentation

virtual BindResult PlotBinaryOperator::bind ( const QList< PlotInstance * > &  curves, PlotBindingTracker &  bindTracker, PlotExpressionBindDomain &  domain, bool  repeatLastBinding = false  )

virtual

Binds the left and right branch expressions.

Handles exhaustive binding.

Implements PlotExpression.

bool PlotBinaryOperator::explicitTime ( ) const

overridevirtual

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

Returns

True if any child returns true.

Reimplemented from PlotExpression.

const PlotExpression* PlotBinaryOperator::left ( ) const

inline

Get the left branch.

Returns

The left branch.

Referenced by PlotBinaryOperatorT< std::minus< double > >::clone(), PlotBinaryOperatorT< std::minus< double > >::sample(), and setLeft().

const PlotExpression* PlotBinaryOperator::right ( ) const

inline

Get the right branch.

Returns

The right branch.

Referenced by PlotBinaryOperatorT< std::minus< double > >::clone(), PlotBinaryOperatorT< std::minus< double > >::sample(), and setRight().

void PlotBinaryOperator::setLeft ( PlotExpression *  left )

inline

Set the left branch.

Does not release the existing branch.

Parameters

left	The new branch.

References left().

void PlotBinaryOperator::setRight ( PlotExpression *  right )

inline

Set the right branch.

Does not release the existing branch.

Parameters

right

The new branch.

References right().
