Constructor Summary

DistributedTaskEvent(TaskManager src, int type)
Constructor typically used for the clearing of the server pool, and also as an intermediate method by the other constructors.

DistributedTaskEvent(TaskManager src, int type, java.lang.Object server)
Used to announce an event associated specifically with a server including the fact that the server is dead or that it has been discarded from the server pool because none of the remaining tasks can avail of it.

DistributedTaskEvent(TaskManager src, int type, Task task)
This is a simple constructor that just takes a task along with the source and event type.

DistributedTaskEvent(TaskManager src, int type, Task task, java.lang.Object server)
The converter specifying both the server and the task associated with the event, e.g.

DistributedTaskEvent

public DistributedTaskEvent(TaskManager src,
                            int type)

                            int type,
                            java.lang.Object server)

Used to announce an event associated specifically with a server including the fact that the server is dead or that it has been discarded from the server pool because none of the remaining tasks can avail of it.

public DistributedTaskEvent(TaskManager src,
                            int type,
                            Task task)

This is a simple constructor that just takes a task along with the source and event type. This is used when the event does not involve a server. e.g. incomplete task specification. This is primarily used by other constructors as an intermediate method.

DistributedTaskEvent

public DistributedTaskEvent(TaskManager src,
                            int type,
                            Task task,
                            java.lang.Object server)

The converter specifying both the server and the task associated with the event, e.g. task completed, task error, task dispatch.
