def abort(): Unit

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.

Attributes

Inherited from:
DelegatedSignalling
def indexFlag: Int

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.

Attributes

Returns

the value of the index flag

Inherited from:
DelegatedSignalling

Checks whether an abort signal has been issued.

Checks whether an abort signal has been issued.

Attributes

Returns

the state of the abort

def setIndexFlag(f: Int): Unit

Sets the value of the index flag.

Sets 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.

Value parameters

f

the value to which the index flag is set.

def tag: Int

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.
