SYNOPSIS

DESCRIPTION

This class is used as a delegate by both CQLRelation and CQLProxNode - two functionally very separate classes that happen to require similar data structures and functionality.

A ModifierSet consists of a ``base'' string together with a set of zero or more type=value pairs, where both type and value are strings. Types may be null, values may not.

METHODS

new()

Creates a new modifier set with the specified base.

getBase()

Returns the base string with which the modifier set was created.

addModifier()

Adds a modifier of the specified type and value to a modifier set.

modifier()

Returns a modifier with a given type, or null if a modifier of that type isn't present.

getModifiers()

Returns a list of modifiers each represented by a 2 element array ref.
