Interface BufferedBlockingConsumer<T>

Type Parameters:

T - the type of the input to the operation

All Superinterfaces:

BlockingConsumer<T>

public interface BufferedBlockingConsumer<T>
extends BlockingConsumer<T>

A BlockingConsumer that retains a maximum number of values in a buffer before sending them to a delegate consumer. Note that any buffered values may need to be flushed periodically.

This maintains the same order of the values.

Method Summary

Modifier and Type	Method and Description
static <T> BufferedBlockingConsumer<T>	bufferLast(BlockingConsumer<T> delegate) Get a BufferedBlockingConsumer that buffers just the last value seen by the consumer.
default void	flush() Flush all of the buffered values to the delegate.
void	flush(Function<T,T> function) Flush all of the buffered values to the delegate by first running each buffered value through the given function to generate a new value to be flushed to the delegate consumer.

Method Detail

flush

default void flush()
            throws InterruptedException

Flush all of the buffered values to the delegate.

Throws:

InterruptedException - if the thread is interrupted while this consumer is blocked

flush

void flush(Function<T,T> function)
    throws InterruptedException

Flush all of the buffered values to the delegate by first running each buffered value through the given function to generate a new value to be flushed to the delegate consumer.

Parameters:

function - the function to apply to the values that are flushed

Throws:

InterruptedException - if the thread is interrupted while this consumer is blocked

bufferLast

static <T> BufferedBlockingConsumer<T> bufferLast(BlockingConsumer<T> delegate)

Get a BufferedBlockingConsumer that buffers just the last value seen by the consumer. When another value is then added to the consumer, this buffered consumer will push the prior value into the delegate and buffer the latest.

The resulting consumer is not threadsafe.

Parameters:

delegate - the delegate to which values should be flushed; may not be null

Returns:

the blocking consumer that buffers a single value at a time; never null
