Constructor Detail

WorkManager.AbstractWork

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

WorkManager.AbstractWork

public WorkManager.AbstractWork(long lWorkId,
                                int nMemberId)
Construct the AbstractWork to be executed on behalf of the specified member (a Work originator).
Parameters:
lWorkId - the Work id
nMemberId - the tagret Member id

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(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

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.
