Package org.HdrHistogram

Class AllValuesIterator

java.lang.Object

org.HdrHistogram.AbstractHistogramIterator

org.HdrHistogram.AllValuesIterator

All Implemented Interfaces:

Iterator<HistogramIterationValue>

public class AllValuesIterator
extends AbstractHistogramIterator
implements Iterator<HistogramIterationValue>

Used for iterating through histogram values using the finest granularity steps supported by the underlying representation. The iteration steps through all possible unit value levels, regardless of whether or not there were recorded values for that value level, and terminates when all recorded histogram values are exhausted.

Constructor Details

AllValuesIterator

public AllValuesIterator(AbstractHistogram histogram)

Parameters:

histogram - The histogram this iterator will operate on

Method Details

reset

public void reset()

Reset iterator for re-use in a fresh iteration over the same histogram data set.

reset

private void reset(AbstractHistogram histogram)

incrementIterationLevel

void incrementIterationLevel()

Specified by:

incrementIterationLevel in class AbstractHistogramIterator

reachedIterationLevel

boolean reachedIterationLevel()

Specified by:

reachedIterationLevel in class AbstractHistogramIterator

Returns:

true if the current position's data should be emitted by the iterator

hasNext

public boolean hasNext()

Description copied from class: AbstractHistogramIterator

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<HistogramIterationValue>

Overrides:

hasNext in class AbstractHistogramIterator

Returns:

true if the iterator has more elements.
