Detailed Description

An evaluator that represents the rest of the command line.

Member Function Documentation

convertToOptionEvaluator()

void Parsnip::RemainderEvaluator::convertToOptionEvaluator ( )

overridevirtual

Make any changes to the parse tree to convert it to an options evaluator.

Implements Parsnip::Evaluator.

Evaluator()

Parsnip::Evaluator::Evaluator

(

Evaluator *

original

)

Upgrade an evaluator.

The original must be a TerminatorEvaluator; other type should never be upgraded. Herein we initialize the new evaluator with the relevant bits.

getNextEvaluator()

Evaluator * Parsnip::RemainderEvaluator::getNextEvaluator ( const StringType &  value ) const

overridevirtual

An evaluator that represents the rest of the command line.

Implements Parsnip::Evaluator.

operator==()

bool Parsnip::RemainderEvaluator::operator== ( const Evaluator &  other ) const

overridevirtual

Check if two evaluators are the same.

Subclasses should override this to check their details.

Parameters

other

Another evaluator to which to compare.

Reimplemented from Parsnip::Evaluator.

Reimplemented in Parsnip::OptionEvaluator.
