Sends an abort signal to other workers.
Sends an abort signal to other workers.
Abort flag being true means that a worker can abort and produce whatever result,
since its result will not affect the final result of computation. An example
of operations using this are find, forall and exists methods.
Returns the value of the index flag.
Returns the value of the index flag.
The index flag holds an integer which carries some operation-specific meaning. For
instance, takeWhile operation sets the index flag to the position of the element
where the predicate fails. Other workers may check this index against the indices
they are working on and return if this index is smaller than their index. Examples
of operations using this are takeWhile, dropWhile, span and indexOf.

Sets the value of the index flag if argument is greater than current value.
Sets the value of the index flag if argument is greater than current value. This method does this atomically.

A read only tag specific to the signalling object.
A read only tag specific to the signalling object. It is used to give specific workers information on the part of the collection being operated on.
Returns string formatted according to given format string.
Returns string formatted according to given format string.
Format strings are as for String.format
(@see java.lang.String.format).
A message interface serves as a unique interface to the part of the collection capable of receiving messages from a different task.
One example of use of this is the
findmethod, which can use the signalling interface to inform worker threads that an element has been found and no further search is necessary.
