that match the given
Predicate. |
void |
forEach(Operation<T> op)
Apply the given
Operation to each item in the stream. |

Transform the stream by creating a new stream that transforms the items
in this stream with the given
Function. |
<R> Stream<R> |
map(MultiFunction<T,R> mapper)
Transform the stream by creating a new stream that transforms the items
in this stream with the given
Function. |
void |
parallelForEach(Operation<T> op)
Apply the given
Operation to each item in the stream, making use
of multiple threads. |

public void forEach(Operation<T> operation, Predicate<T> stopPredicate)
StreamOperation to each item in the stream. Items are
presented to the Operation in the order they appear in the
stream. The given Predicate can be used to stop processing of the
stream once some condition is met.
Note: for an unbounded stream, this method will never return unless some form of exception is raised or the condition of the stopPredicate is met.
public int forEach(Operation<T> operation, int limit)
StreamOperation to each item in the stream. Items are
presented to the Operation in the order they appear in the
stream. The given Predicate can be used to stop processing of the
stream once some condition is met.
Note: for an unbounded stream, this method will never return unless some form of exception is raised or the condition of the stopPredicate is met.
public void parallelForEach(Operation<T> op)
StreamOperation to each item in the stream, making use
of multiple threads. The order in which operations are performed on the
stream is not guaranteed.
This method is intended to be a shortcut to calling
Parallel.forEachUnpartitioned(Iterator, Operation).
Note: for an unbounded stream, this method will never return unless some form of exception is raised.
parallelForEach in interface Stream<T>op - the Operation to applypublic void parallelForEach(Operation<T> op, ThreadPoolExecutor pool)
StreamOperation to each item in the stream, making use
of multiple threads. The order in which operations are performed on the
stream is not guaranteed.
This method is intended to be a shortcut to calling
Parallel.forEachUnpartitioned(Iterator, Operation, ThreadPoolExecutor).
Note: for an unbounded stream, this method will never return unless some form of exception is raised.
