Class CallableLocatorProcedures

java.lang.Object

com.pivotal.gemfirexd.internal.client.am.CallableLocatorProcedures

public class CallableLocatorProcedures
extends Object

Contains the necessary methods to call the stored procedure that operate on LOBs identified by locators. An instance of this class will be initialized with a Connection parameter and all calls will be made on that connection.

The class makes sure that each procedure call is only prepared once per instance. Hence, it will keep references to CallableStatement objects for procedures that have been called through this instance. This makes it possible to prepare each procedure call only once per Connection.

Since LOBs can not be parameters to stored procedures, the framework should make sure that calls involving a byte[] or String that does not fit in a VARCHAR (FOR BIT DATA), are split into several calls each operating on a fragment of the LOB.
