Constructor Details

ArrayShortBatchIterator

public ArrayShortBatchIterator(ArrayContainer array,
 int initialSkipCount)

Method Details

next

public int next(short[] buffer,
 int offset,
 int maxCount)

Description copied from interface: ContainerShortBatchIterator

Writes to buffer the next batch of values, and returns how much of the buffer was used.

Specified by:

next in interface ContainerShortBatchIterator

Parameters:

buffer - the buffer to write values onto.

offset - first position to start writing in buffer.

maxCount - max number of elements to write to buffer.

Returns:

how many values were written.

hasNext

public boolean hasNext()

Description copied from interface: ContainerShortBatchIterator

Whether the underlying container is exhausted or not

Specified by:

hasNext in interface ContainerShortBatchIterator

Returns:

true if there is data remaining

forEach

public boolean forEach(ShortConsumer sc)

Description copied from interface: ContainerShortBatchIterator

Starting from the next iterator position (if any), feed values to the consumer until it returns false. After each value is consumed, the current iterator position is moving forward; eg, a call to forEach that consumes 4 elements effectively works as if next was called 4 times.

Specified by:

forEach in interface ContainerShortBatchIterator

Parameters:

sc - a ShortConsumer to feed values to.

Returns:

false if the processing was stopped by the consumer returning false, true otherwise.
