NAME
Text::Query::Solve - Base class for query resolutionSYNOPSIS
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.
