AtomicIndexFlag

trait AtomicIndexFlag extends Signalling

A mixin trait that implements index flag behaviour using atomic integers. The setIndex operation is wait-free, while conditional set operations setIndexIfGreater and setIndexIfLesser are lock-free and support only monotonic changes.

Abstract Value Members

  1. abstract 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.

  2. abstract def isAborted: Boolean

    Checks whether an abort signal has been issued.

    Checks whether an abort signal has been issued.

    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 state of the abort

  2. final def ##(): Int

    Equivalent to x.hashCode except for boxed numeric types and null.

    Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

    returns

    a hash value consistent with ==

  6. final def asInstanceOf[T0]: T0

    Cast the receiver object to be of type T0.

    Cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

    returns

    the receiver object.

    Definition Classes
    Any
    Exceptions thrown

    ClassCastException if the receiver object is not an instance of the erasure of type T0.

  7. def clone(): AnyRef

    Create a copy of the receiver object.

    The default implementation of the clone method is platform dependent.

    returns

  12. final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (that) is a reference to the receiver object (this).

    Tests whether the argument (that) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.

  18. 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.

    Test whether the dynamic type of the receiver object is T0.

    Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.
