public Class LinearIterator

extends AbstractHistogramIterator
implements Iterator<HistogramIterationValue>
Class Inheritance
All Implemented Interfaces
java.util.Iterator
Imports
java.util.Iterator
Used for iterating through histogram 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.

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
