Constructor Detail

CreateNewChildThread

public CreateNewChildThread(java.lang.Object name,
                            Prim parent,
                            ComponentDescription cmp,
                            Context parms)
                     throws SmartFrogException

Creates a CreateNewChildThread that will upon running, execute the given CreateNewChild. Parent cannot be null

Parameters:

name - child name

parent - parent component

cmp - component description

parms - Context

Throws:

SmartFrogException - if callable is null

CreateNewChildThread

public CreateNewChildThread(java.lang.Object name,
                            Prim parent,
                            ComponentDescription cmp,
                            Context parms,
                            Prim deployer)
                     throws SmartFrogException

Creates a CreateNewChildThread that will upon running, execute the given CreateNewChild. If parent null then it will create a independent application but a deployer needs to be provided

Parameters:

name - child name

parent - parent component

cmp - component description

parms - Context

deployer - deployer

Throws:

SmartFrogException - if callable is null

Method Detail

isCancelled

public boolean isCancelled()

Check if the state as CANCELLED

Returns:

boolean

isDone

public boolean isDone()

Checks if the tasks is done

Returns:

boolean

cancel

public boolean cancel(boolean mayInterruptIfRunning)

Cancel the thread

Parameters:

mayInterruptIfRunning - boolean to interrupt

Returns:

boolean

get

public java.lang.Object get()
                     throws java.lang.InterruptedException,
                            SmartFrogException

Wait

Returns:

Object

Throws:

java.lang.InterruptedException - if interrupted

SmartFrogException - if failed

get

public java.lang.Object get(long timeout)
                     throws java.lang.InterruptedException,
                            SmartFrogException

Wait

Parameters:

timeout - timeout

Returns:

Object

Throws:

java.lang.InterruptedException - if interrupted

SmartFrogException - if failed

done

protected void done()

Protected method invoked when this task transitions to state isDone (whether normally or via cancellation). The default implementation does nothing. Subclasses may override this method to invoke completion callbacks or perform bookkeeping. Note that you can query status inside the implementation of this method to determine whether this task has been cancelled.

set

protected void set(java.lang.Object v)

Sets the result of this Future to the given value unless this future has already been set or has been cancelled.

Parameters:

v - the value

setException

protected void setException(java.lang.Throwable t)

Causes this future to report an ExecutionException with the given throwable as its cause, unless this Future has already been set or has been cancelled.

Parameters:

t - the cause of failure.

run

public void run()

Sets this Future to the result of computation unless it has been cancelled.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread
