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.
- 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.

Hey! The above document had some coding errors, which are explained
below:
- Around line 98:
- You forgot a '=back' before '=head1'
