.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module provides a virtual base class for query resolution.
.PP
It defines the \f(CW\*(C`match\*(C'\fR and \f(CW\*(C`matchscalar\*(C'\fR method that is called by the \f(CW\*(C`Text::Query\*(C'\fR
object to apply a query on a data source.
.SH METHODS
.IX Header "METHODS"
.IP "match (EXPR [TARGET])" 4
.IX Item "match (EXPR [TARGET])"
If \f(CW\*(C`TARGET\*(C'\fR is a scalar, \f(CW\*(C`match\*(C'\fR returns a true value if the data source 
specified by \f(CW\*(C`TARGET\*(C'\fR matches the \f(CW\*(C`EXPR\*(C'\fR query expression.  If 
\&\f(CW\*(C`TARGET\*(C'\fR is not given, the match is made against \f(CW$_\fR.
.Sp
If \f(CW\*(C`TARGET\*(C'\fR is an array, \f(CW\*(C`match\*(C'\fR 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.
.Sp
If \f(CW\*(C`TARGET\*(C'\fR is a reference to an array, \f(CW\*(C`match\*(C'\fR returns a reference to 
a (possibly empty) list of all matching elements.
.IP "matchscalar (EXPR [TARGET])" 4
.IX Item "matchscalar (EXPR [TARGET])"
Behaves just like \f(CW\*(C`MATCH\*(C'\fR when \f(CW\*(C`TARGET\*(C'\fR is a scalar or is not given.
