Class MultiReadReceiveOperationHandler

java.lang.Object

org.openspaces.events.polling.receive.AbstractNonBlockingReceiveOperationHandler

org.openspaces.events.polling.receive.AbstractMemoryOnlySearchReceiveOperationHandler

org.openspaces.events.polling.receive.MultiReadReceiveOperationHandler

All Implemented Interfaces:

ReceiveOperationHandler

public class MultiReadReceiveOperationHandler
extends AbstractMemoryOnlySearchReceiveOperationHandler

First tries and perform a GigaSpace.readMultiple(Object,int) using the provided template and configured maxEntries (defaults to 50). If no values are returned, will perform a blocking read operation using GigaSpace.read(Object,long).

Specified by:

doReceiveBlocking in class AbstractNonBlockingReceiveOperationHandler

Throws:

DataAccessException

doReceiveNonBlocking

protected Object doReceiveNonBlocking(Object template,
                                      GigaSpace gigaSpace)
                               throws DataAccessException

Perform a GigaSpace.readMultiple(Object,int) using the provided template and configured maxEntries (defaults to 50). This is a non blocking operation.

Specified by:
