Class EntityBatchHandler

java.lang.Object

org.sakaiproject.entitybroker.rest.EntityBatchHandler

public class EntityBatchHandler
extends Object

This handles batch operations internally as much as possible, the idea is to provide for a standard way to reduce huge numbers of calls down to 1 call to the server which puts the data together into a single response
