Method Detail

resetIterator

void resetIterator(AbstractHistogram histogram)

hasNext

public boolean hasNext()

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 java.util.Iterator<HistogramIterationValue>

Returns:

true if the iterator has more elements.

next

public HistogramIterationValue next()

Returns the next element in the iteration.

Specified by:

next in interface java.util.Iterator<HistogramIterationValue>

Returns:

the HistogramIterationValue associated with the next element in the iteration.

remove

public void remove()

Not supported. Will throw an UnsupportedOperationException.

Specified by:

remove in interface java.util.Iterator<HistogramIterationValue>

incrementIterationLevel

abstract void incrementIterationLevel()

reachedIterationLevel

abstract boolean reachedIterationLevel()

Returns:

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

getPercentileIteratedTo

double getPercentileIteratedTo()

getPercentileIteratedFrom

double getPercentileIteratedFrom()

getValueIteratedTo

long getValueIteratedTo()

exhaustedSubBuckets

private boolean exhaustedSubBuckets()

incrementSubBucket

void incrementSubBucket()
