Description copied from interface: Parser

Derive a new Parser instance from the receiving instance.

The new parser will match the same text as the given parser, but the object parsed will be transformed by the given Function.

Specified by:

transform in interface AbstractParser<T>

Specified by:

transform in interface Parser<T>

Type Parameters:

V - the type of the object of the new parser, post-transformation

Parameters:

transform - the transformation to apply to the object given by application of this parser

Returns:

a new Parser instance which applies the given transformation

parseSubstringImpl

public ParseResult<T> parseSubstringImpl(ParseState state)

Specified by:

parseSubstringImpl in interface AbstractParser<T>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
