Text::Query::Solve - Base class for query resolution
package Text::Query::SolveSource;
use Text::Query::Parse;
use vars qw(@ISA);
@ISA = qw(Text::Query::Solve);
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.
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.
Behaves just like MATCH when TARGET is a scalar or is not given.
