Repository Guide

Repository API

Repository – data store.
Represents a collection of RepositoryItems. the interface

MutableRepository – The interface defines functions for four operations: creating, adding, updating, and removing repository items.

RepositoryItem : like a JavaBean that is similar to a row in a table that is made up of properties. Each repository item must have an identifier, which is called a repository ID.

RepositoryItem that can be updated as specified by the interface

RepositoryItemDescriptor –  Each item type is described by a Repository item descriptor (also called a RepositoryView) interface . Gives a name to the type, and also describes the properties for that type.

ItemDescriptorImpl – implements RepositoryItemDescriptor

atgrepositorypropertieschanged : When a repository item is modified, its item descriptor broadcasts locally a PropertiesChangedEvent. In addition to its type, a PropertiesChangedEvent contains the following:- A Map in which the keys are RepositoryPropertyDescriptors and the values are the new property values.- The item that is changed.- The repository ID of the item that is changed.- The item that is changed.-The item descriptor of the item that is changed. If you have a component that you want to be notified when repository item properties change, it can implement the atg.repository.PropertiesChangedListener interface. You can add your PropertiesChangedListener implementation to the atg.repository.ItemDescriptorImpl returned by the repository.getItemDescriptor() method, using the method ItemDescriptorImpl.addPropertiesChangedListener.
