Text::Query::Solve(3)                      User Contributed Perl Documentation


NAME
       Text::Query::Solve - Base class for query resolution

SYNOPSIS
           package Text::Query::SolveSource;

           use Text::Query::Parse;

           use vars qw(@ISA);

           @ISA = qw(Text::Query::Solve);

DESCRIPTION
       This module provides a virtual base class for query resolution.

       It defines the "match" and "matchscalar" method that is called by the
       "Text::Query" object to apply a query on a data source.

METHODS
       match (EXPR [TARGET])
           If "TARGET" is a scalar, "match" returns a true value if the data
           source specified by "TARGET" matches the "EXPR" query expression.
           If "TARGET" is not given, the match is made against $_.

           If "TARGET" is an array, "match" returns a (possibly empty) list of
           all matching elements.  If the elements of the array are references
           to sub- arrays, the match is done against the first element of each
           sub-array.  This allows arbitrary information (e.g. filenames) to
           be associated with each data source to match.

           If "TARGET" is a reference to an array, "match" returns a reference
           to a (possibly empty) list of all matching elements.

       matchscalar (EXPR [TARGET])
           Behaves just like "MATCH" when "TARGET" is a scalar or is not
           given.
