Class CacheOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.spi.impl.AbstractNamedOperation

com.hazelcast.cache.impl.operation.CacheOperation

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, NamedOperation, PartitionAwareOperation, ServiceNamespaceAware

Direct Known Subclasses:

CacheExpireBatchBackupOperation, CacheMergeOperation, CachePutAllBackupOperation, CachePutAllOperation, CacheSetExpiryPolicyBackupOperation, CacheSetExpiryPolicyOperation, KeyBasedCacheOperation

public abstract class CacheOperation
extends AbstractNamedOperation
implements PartitionAwareOperation, ServiceNamespaceAware, IdentifiedDataSerializable

Base Cache Operation. Cache operations are named operations. Key based operations are subclasses of this base class providing a cacheRecordStore access and partial backup support.

Method Detail

getServiceName

public final String getServiceName()

Overrides:

getServiceName in class Operation

beforeRun

public final void beforeRun()
                     throws Exception

Description copied from class: Operation

The beforeRun is called before either the Operation.run() or the Operation.call() method is called. runs before wait-support

Overrides:

beforeRun in class Operation

Throws:

Exception

dispose

protected void dispose()

Implementers can override to release associated resources upon a successful execution or failure.

beforeRunInternal

protected void beforeRunInternal()

Implementers can override this method to make a specific execution.

onInvocationException

public ExceptionAction onInvocationException(Throwable throwable)

Description copied from class: Operation

Called when an Exception/Error is thrown during an invocation. Invocation process will continue, it will retry or fail according to returned ExceptionAction.

This method is called on caller side of the invocation.

Overrides:

onInvocationException in class Operation

Parameters:

throwable - Exception/Error thrown during invocation

Returns:

ExceptionAction

logError

public void logError(Throwable e)

Description copied from class: Operation

Logs Exception/Error thrown during operation execution. Operation implementations can override this behaviour according to their needs.

This method is called on node & thread that's executing the operation.

Overrides:

logError in class Operation

Parameters:

e - Exception/Error thrown during operation execution
