DoInBackground(Object[])
Obsolete.

Override this method to perform a computation on a background thread.

Equals(Object)

Indicates whether some other object is "equal to" this one.

(Inherited from Object)
Execute(IRunnable)
Obsolete.

Convenience version of #execute(Object...) for use with a simple Runnable object.

Execute(Object[])
Obsolete.

Executes the task with the specified parameters.

ExecuteOnExecutor(IExecutor, Object[])
Obsolete.

Executes the task with the specified parameters.

Get()
Obsolete.

Waits if necessary for the computation to complete, and then retrieves its result.

Get(Int64, TimeUnit)
Obsolete.

Waits if necessary for at most the given time for the computation to complete, and then retrieves its result.

GetHashCode()

Returns a hash code value for the object.

(Inherited from Object)
GetStatus()
Obsolete.

Returns the current status of this task.

Wakes up a single thread that is waiting on this object's monitor.

(Inherited from Object)
NotifyAll()

Wakes up all threads that are waiting on this object's monitor.

(Inherited from Object)
OnCancelled()
Obsolete.

Applications should preferably override #onCancelled(Object).

OnCancelled(Object)
Obsolete.

ToString()

Returns a string representation of the object.

(Inherited from Object)

(Inherited from Object)
Wait(Int64)

Causes the current thread to wait until either another thread invokes the java.lang.Object#notify() method or the java.lang.Object#notifyAll() method for this object, or a specified amount of time has elapsed.

(Inherited from Object)
