All Implemented Interfaces:

ExternalizableLite, PortableObject, Invocable, InvocableInOrder, PriorityTask, Serializable, Runnable

Enclosing class:

WorkManager

protected static class WorkManager.SendFeedback
extends WorkManager.AbstractWork

Invocable task that delivers a WorkEvent to a WorkListener.

Since there has to be a guaranteed order between the SendFeedBack execution and processing of the WorkItem completion, we should always process this on the service thread (see COH-14990).

Constructor Detail

SendFeedback

public SendFeedback()

Default constructor (necessary for a lite serialization).

SendFeedback

public SendFeedback(WorkManager.WorkStatus status)

Construct a SendFeedback task.

Parameters:

status - the work status

Method Detail

init

public void init(InvocationService service)

Called by the InvocationService exactly once on this Invocable object as part of its initialization.

Specified by:

init in interface Invocable

Overrides:

init in class AbstractInvocable

Parameters:

service - the containing InvocationService

run

public void run()

Called exactly once by the InvocationService to invoke this Invocable object.

getWorkStatus

public WorkManager.WorkStatus getWorkStatus()

Return a WorkStatus object for this feedback.

Returns:

a WorkStatus object

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

Overrides:

readExternal in class WorkManager.AbstractWork

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

Overrides:

writeExternal in class WorkManager.AbstractWork

Parameters:

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

Throws:

IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader in)
                  throws IOException

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Specified by:

readExternal in interface PortableObject

Overrides:

readExternal in class WorkManager.AbstractWork

Parameters:

in - the PofReader from which to read the object's state

Throws:

IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws IOException

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Specified by:

writeExternal in interface PortableObject

Overrides:

writeExternal in class WorkManager.AbstractWork

Parameters:

out - the PofWriter to which to write the object's state

Throws:

IOException - if an I/O error occurs
