Test two objects for inequality.
Test two objects for inequality.
true
if !(this == that), false otherwise.
Equivalent to x.hashCode

.
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
.
a hash value consistent with ==
The expression x == that
is equivalent to if (x eq null) that eq null else x.equals(that)
.
The expression x == that

the object to compare against this object for equality.
true
if the receiver object is equivalent to the argument; false
otherwise.
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.
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.

Create a copy of the receiver object.
Tests whether the argument (arg0

Tests whether the argument (arg0

The eq
method implements an equivalence relation on
non-null instances of AnyRef
, and has three additional properties:
x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.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
).
true
if the argument is a reference to the receiver object; false
otherwise.
The equality method for reference types.
Called by the garbage collector on the receiver object when there are no more references to the object.

The details of when and if the finalize
method is invoked, as
well as the interaction between finalize
and non-local returns
and exceptions, are all platform dependent.

Format strings are as for String.format
(@see java.lang.String.format).

The hashCode method for reference types.
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
.
