# CQL::ModifierSet(3pm)

represents a base string and modifier strings

## NAME

CQL::ModifierSet - represents a base string and modifier strings

## 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.
