Enclosing class:

CompositeOffsetsPostingsEnum

private static final class CompositeOffsetsPostingsEnum.BoundsCheckingPostingsEnum
extends java.lang.Object

This class is used to ensure we don't over iterate the underlying postings enum by keeping track of the position relative to the frequency. Ideally this would've been an implementation of a PostingsEnum but it would have to delegate most methods and it seemed easier to just wrap the tweaked method.
