NAME

       CQL::ProxNode - represents a PROX node in a CQL parse tree

SYNOPSIS

           use CQL::ProxNode;
           my $node = CQL::ProxNode->new( left => $left );
           $node->addSecondTerm( $right );

DESCRIPTION

METHODS

new()
       Creates a new, incomplete, proximity node with the specified left-hand side.  No right-
       hand side is specified at this stage: that must be specified later, using the
       addSecondSubterm() method.  (That may seem odd, but it's just easier to write the parser
       that way.)

       Proximity paramaters may be added at any time, before or after the right-hand-side sub-
       tree is added.

           my $prox = CQL::ProxNode->new( $term );
