Call

public interface Call implements Serializable, Cloneable
Call defines the interface used primarily by TopLink queries and query mechanisms to perform the necessary actions (read, insert, update, delete) on the data store. A Call can collaborate with an Accessor to perform its responsibilities. The only explicit requirement of a Call is that it be able to supply the appropriate query mechanism for performing its duties. Otherwise, the Call is pretty much unrestricted as to how it should perform its responsibilities.
