public Class DoubleRecordedValuesIterator

extends Object
implements Iterator<DoubleHistogramIterationValue>
Class Inheritance
All Implemented Interfaces
java.util.Iterator
Imports
java.util.Iterator
Used for iterating through DoubleHistogram values 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.

Method Summary

Modifier and TypeMethod and Description
public boolean
hasNext()

Implements java.util.Iterator.hasNext.

Returns true if the iteration has more elements.
public DoubleHistogramIterationValue
next()

Implements java.util.Iterator.next.

Returns the next element in the iteration.
public void
remove()

Overrides default java.util.Iterator.remove.

Removes from the underlying collection the last element returned by this iterator (optional operation).
public void
reset()

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

Method Detail

public boolean hasNext()

Implements java.util.Iterator.hasNext.

Doc from java.util.Iterator.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.)

Returns:boolean

true if the iteration has more elements

public void remove()

Overrides default java.util.Iterator.remove.

Doc from java.util.Iterator.remove.

Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next.

The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method, unless an overriding class has specified a concurrent modification policy.

The behavior of an iterator is unspecified if this method is called after a call to the forEachRemaining method.
