trait ExecutionContextTasks extends Tasks
This tasks implementation uses execution contexts to spawn a parallel computation.
As an optimization, it internally checks whether the execution context is the
standard implementation based on fork/join pools, and if it is, creates a
ForkJoinTaskSupport
that shares the same pool to forward its request to it.
Otherwise, it uses an execution context exclusive Tasks
implementation to
divide the tasks into smaller chunks and execute operations on it.

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

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 ofAnyRef
, and has three additional properties:- It is consistent: for any non-null instances
x
andy
of typeAnyRef
, multiple invocations ofx.eq(y)
consistently returnstrue
or consistently returnsfalse
. - For any non-null instance
x
of typeAnyRef
,x.eq(null)
andnull.eq(x)
returnsfalse
. null.eq(null)
returnstrue
.
When overriding the
equals
orhashCode
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.
