Constructor Detail

WorkManager.CollectMembershipInfo

public WorkManager.CollectMembershipInfo()

Default constructor (necessary for a lite serialization).

WorkManager.CollectMembershipInfo

public WorkManager.CollectMembershipInfo(Member memberServer)

Construct the task for a given member server (could be null for a client).

Parameters:

memberServer - the target Member

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

run

public void run()

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

Specified by:

run in interface Invocable

Specified by:

run in interface java.lang.Runnable

readExternal

public void readExternal(java.io.DataInput in)
                  throws java.io.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:

java.io.IOException - if an I/O exception occurs

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

writeExternal

public void writeExternal(java.io.DataOutput out)
                   throws java.io.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:

java.io.IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader in)
                  throws java.io.IOException

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

Specified by:

readExternal in interface PortableObject

Parameters:

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

Throws:

java.io.IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter out)
                   throws java.io.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

Parameters:

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

Throws:

java.io.IOException - if an I/O error occurs
