Class ScheduledTaskDescriptor

java.lang.Object

com.hazelcast.scheduledexecutor.impl.ScheduledTaskDescriptor

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable

public class ScheduledTaskDescriptor
extends Object
implements IdentifiedDataSerializable

Metadata holder for scheduled tasks. Active tasks, eg. not suspended, hold a non-null future reference. Suspended ones, i.e., backups or on-going migration have future set to null.

For partition owned tasks, writes to the fields are done through the partition-thread. For member owned tasks, writes to the fields are done through the generic-thread. Reads on the fields, follow the same principal.

Method Detail

getDefinition

public TaskDefinition getDefinition()

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

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable
