All Implemented Interfaces:

ExternalizableLite, Invocable, InvocableInOrder, PriorityTask, Serializable, Runnable

Direct Known Subclasses:

Enclosing class:

WorkManager

protected abstract static class WorkManager.AbstractWork
extends AbstractInvocable
implements ExternalizableLite

Base class for Invocable tasks related to the WorkManager. Note, that aside of the ScheduleWork task all other tasks have to be scheduled immediately.

Field Summary

protected long	m_lWorkId The work id.
protected int	m_nMemberId The Work originator Member id.

Fields inherited from interface com.tangosol.net.PriorityTask

SCHEDULE_FIRST, SCHEDULE_IMMEDIATE, SCHEDULE_STANDARD, TIMEOUT_DEFAULT, TIMEOUT_NONE

Constructor Summary

WorkManager.AbstractWork()
Default constructor (necessary for a lite serialization).

WorkManager.AbstractWork(long lWorkId, int nMemberId)
Construct the AbstractWork to be executed on behalf of the specified member (a Work originator).

Method Summary

Member	getMember() Return a Work originator's Member object.
int	getMemberId() Return a Work originator's Member id.
int	getSchedulingPriority() Obtain this task's scheduling priority. Valid values are one of the SCHEDULE_* constants.
long	getWorkId() Return a Work id.
void	readExternal(DataInput in) Restore the contents of this object by loading the object's state from the passed DataInput object.
void	writeExternal(DataOutput out) Save the contents of this object by storing the object's state into the passed DataOutput object.

WorkManager.AbstractWork

public WorkManager.AbstractWork(long lWorkId,
                                int nMemberId)

Construct the AbstractWork to be executed on behalf of the specified member (a Work originator).

Method Detail

getSchedulingPriority

public int getSchedulingPriority()

Obtain this task's scheduling priority. Valid values are one of the SCHEDULE_* constants.

This implementation returns SCHEDULE_STANDARD.

Specified by:

getSchedulingPriority in interface PriorityTask

Overrides:

getSchedulingPriority in class AbstractInvocable

Returns:

this task's scheduling priority

getWorkId

public long getWorkId()

Return a Work id.

Returns:

a Work id

getMemberId

public int getMemberId()

Return a Work originator's Member id.

Returns:

a Member id

getMember

public Member getMember()

Return a Work originator's Member object.

Returns:

a Member object or null

readExternal

public void readExternal(DataInput in)
                  throws IOException

Restore the contents of this object by loading the object's state from the passed DataInput object.

Specified by:

readExternal in interface ExternalizableLite

Parameters:

in - the DataInput stream to read data from in order to restore the state of this object

Throws:

IOException - if an I/O exception occurs

NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

writeExternal

public void writeExternal(DataOutput out)
                   throws IOException

Save the contents of this object by storing the object's state into the passed DataOutput object.

Specified by:

writeExternal in interface ExternalizableLite

Parameters:

out - the DataOutput stream to write the state of this object to

Throws:

IOException - if an I/O exception occurs
