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 );
