public Class DoubleLinearIterator

extends Object
implements Iterator<DoubleHistogramIterationValue>
Class Inheritance
All Implemented Interfaces
java.util.Iterator
Imports
java.util.Iterator
Used for iterating through DoubleHistogram values in linear steps. The iteration is performed in steps of valueUnitsPerBucket in size, terminating when all recorded histogram values are exhausted. Note that each iteration "bucket" includes values up to and including the next bucket boundary value.

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(final double
The size (in value units) of each bucket iteration.
valueUnitsPerBucket)

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

public DoubleLinearIterator(final DoubleHistogram histogram, final double valueUnitsPerBucket)
Parameters
histogram:DoubleHistogram

The histogram this iterator will operate on

valueUnitsPerBucket:double

The size (in value units) of each bucket iteration.

Method Detail

hasNextback to summary
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 DoubleHistogramIterationValue next()

Returns the next element in the iteration.

Returns:DoubleHistogramIterationValue

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.

public void reset(final double valueUnitsPerBucket)

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

Parameters
valueUnitsPerBucket:double

The size (in value units) of each bucket iteration.
