Class NamedElementHolder<T extends NamedElement>

java.lang.Object

ru.curs.celesta.score.NamedElementHolder<T>

Type Parameters:

T - type of named elements in the collection.

All Implemented Interfaces:

Iterable<T>, Collection<T>

public abstract class NamedElementHolder<T extends NamedElement>
extends Object
implements Collection<T>

A collection of named elements that may only contain one element per each name. Provides uniqueness of names and access by name. For example these may be tables in a grain, fields in a key etc. The implementation of interface Collection is done only for the purpose of ObjectAid utility to correctly build a UML diagram (taking a field of NamedElementHolder type as a multi-reference).
