Types ¶

type FindOp ¶

type FindOp struct {
	terminal.TODOOperation
	// contains filtered or unexported fields
}

*

A short-circuiting {@code TerminalOp} that searches for an element in a
stream pipeline, and terminates when it finds one. Implements both
find-first (find the first element in the encounter order) and find-any
(find any element, may not be the first in encounter order.) *
@param <T> the output type of the stream pipeline
@param <O> the result type of the find operation, typically an optional
type

func NewFindOp ¶

func NewFindOp(mustFindFirst bool, presentPredicate predicate.Predicater, sinkSupplier func() *FindSink) *FindOp

*

Constructs a {@code Operation}. *
@param mustFindFirst if true, must find the first element in
encounter order, otherwise can find any element
@param shape stream shape of elements to search
@param emptyValue result value corresponding to "found nothing"
@param presentPredicate {@code Predicate} on result value
corresponding to "found something"
@param sinkSupplier supplier for a {@code TerminalSink} implementing
the matching functionality

func NewFindOp2 ¶

func NewFindOp2(mustFindFirst bool, presentPredicate predicate.Predicater) *FindOp

func (FindOp) EvaluateParallel ¶

func (op FindOp) EvaluateParallel(ctx context.Context, spliterator spliterator.Spliterator) optional.Optional

func (FindOp) EvaluateSequential ¶

func (op FindOp) EvaluateSequential(ctx context.Context, spliterator spliterator.Spliterator) optional.Optional

func (FindOp) MakeSink ¶

func (op FindOp) MakeSink() *FindSink

type FindSink ¶

type FindSink struct {
	terminal.TODOSink
	// contains filtered or unexported fields
}

func NewFindSink ¶

func NewFindSink() *FindSink

func (*FindSink) Accept ¶

func (sink *FindSink) Accept(value interface{})

stores only first value

func (*FindSink) CancellationRequested ¶

func (sink *FindSink) CancellationRequested() bool

return true if found

func (*FindSink) Get ¶

func (sink *FindSink) Get() optional.Optional

type FindTask ¶

type FindTask struct {
	terminal.TODOShortCircuitTask
	// contains filtered or unexported fields
}

func (*FindTask) DoLeaf ¶

func (task *FindTask) DoLeaf(ctx context.Context) terminal.Sink

func (*FindTask) MakeChild ¶

func (task *FindTask) MakeChild(spliterator spliterator.Spliterator) terminal.Task

func (*FindTask) OnCompletion ¶

func (task *FindTask) OnCompletion(caller terminal.Task)

func (*FindTask) WithParent ¶

func (task *FindTask) WithParent(parent *FindTask, spliterator spliterator.Spliterator) *FindTask

*

Constructor for non-root nodes. *
@param parent parent task in the computation tree
@param spliterator the {@code Spliterator} for the portion of the
computation tree described by this task

func (*FindTask) WithSpliterator ¶

func (task *FindTask) WithSpliterator(op FindOp, spliterator spliterator.Spliterator) *FindTask

*

Constructor for root tasks. *
@param helper the {@code PipelineHelper} describing the stream pipeline
up to this operation
@param spliterator the {@code Spliterator} describing the source for this
pipeline
