Class CacheGetAllOperation

java.lang.Object

com.hazelcast.spi.Operation

com.hazelcast.spi.impl.AbstractNamedOperation

com.hazelcast.cache.impl.operation.CacheGetAllOperation

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, AllowedDuringPassiveState, NamedOperation, PartitionAwareOperation, ReadonlyOperation

public class CacheGetAllOperation
extends AbstractNamedOperation
implements ReadonlyOperation

Gets all keys from the cache.

CacheGetAllOperationFactory creates this operation.

Functionality: Filters out the partition keys and calls ICacheRecordStore.getAll(java.util.Set, javax.cache.expiry.ExpiryPolicy)

Constructor Detail

CacheGetAllOperation

public CacheGetAllOperation(String name,
                            Set<Data> keys,
                            javax.cache.expiry.ExpiryPolicy expiryPolicy)

CacheGetAllOperation

public CacheGetAllOperation()

Method Detail

run

public void run()

Description copied from class: Operation

Runs the operation. Either the Operation.run() or Operation.call() method should be implemented; not both. Runs after wait-support, supposed to do actual operation

Overrides:

run in class Operation

See Also:

Operation.call()

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID

toString

protected void toString(StringBuilder sb)

Description copied from class: Operation

A template method allows for additional information to be passed into the Operation.toString() method. So an Operation subclass can override this method and add additional debugging content. The default implementation does nothing so one is not forced to provide an empty implementation. It is a good practice to always call the super.toString(stringBuffer) when implementing this method to make sure that the super class can inject content if needed.

Overrides:

toString in class AbstractNamedOperation

Parameters:

sb - the StringBuilder to add the debug info to.

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class AbstractNamedOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class AbstractNamedOperation

Throws:

IOException

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

getResponse

public Object getResponse()

Description copied from class: Operation

Called if and only if Operation.returnsResponse() returned true, shortly after Operation.run() returns.

Overrides:

getResponse in class Operation

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID
