Member Function Documentation

◆ evalLeftToRight()

bool Bagel::SpaceBar::CBagExpression::evalLeftToRight ( bool  negFl = false,
CBagVar &  result = *_tempVar 
)

Same as evaluate above except it evaluates left to right and preserves the value of the previous evaluation in the loop. Provides partial evaluation hierarchy support.

◆ setInfo()

ParseCodes Bagel::SpaceBar::CBagExpression::setInfo ( CBagIfstream &  istr)
overridevirtual

Reimplemented from Bagel::SpaceBar::CBagParseObject.
