IBaseStream Interface

Base interface for streams, which are sequences of elements supporting sequential and parallel aggregate operations.

Remarks

Base interface for streams, which are sequences of elements supporting sequential and parallel aggregate operations. The following example illustrates an aggregate operation using the stream types Stream and IntStream, computing the sum of the weights of the red widgets:

{@code
                int sum = widgets.stream()
                                 .filter(w -> w.getColor() == RED)
                                 .mapToInt(w -> w.getWeight())
                                 .sum();
            }

See the class documentation for Stream and the package documentation for java.util.stream for additional specification of streams, stream operations, stream pipelines, and parallelism, which governs the behavior of all stream types.

Properties

Handle

Gets the JNI value of the underlying Android object.

(Inherited from IJavaObject)
IsParallel
JniIdentityHashCode

Returns the value of java.lang.System.identityHashCode() for the wrapped instance.

(Inherited from IJavaPeerable)
JniManagedPeerState

State of the managed peer.

(Inherited from IJavaPeerable)
JniPeerMembers

Member access and invocation support.

(Inherited from IJavaPeerable)
PeerReference

Returns a JniObjectReference of the wrapped Java object instance.

(Inherited from IJavaPeerable)

Methods

Close()

Closes this stream, causing all close handlers for this stream pipeline to be called.

Disposed()

Called when the instance has been disposed.

(Inherited from IJavaPeerable)
DisposeUnlessReferenced()

If there are no outstanding references to this instance, then calls Dispose(); otherwise, does nothing.

(Inherited from IJavaPeerable)
Finalized()

Called when the instance has been finalized.

(Inherited from IJavaPeerable)
Iterator()

Returns an iterator for the elements of this stream.

OnClose(IRunnable)

Returns an equivalent stream with an additional close handler.

Parallel()

Returns an equivalent stream that is parallel.

Sequential()

Returns an equivalent stream that is sequential.

SetJniIdentityHashCode(Int32)

Set the value returned by JniIdentityHashCode.

(Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates) (Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)

Set the value returned by PeerReference.

(Inherited from IJavaPeerable)
Spliterator()

Returns a spliterator for the elements of this stream.

Unordered()

Returns an equivalent stream that is unordered.

UnregisterFromRuntime()

Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations.

(Inherited from IJavaPeerable)

Extension Methods

JavaCast<TResult>(IJavaObject)

Performs an Android runtime-checked type conversion.
