All Superinterfaces:

Cloneable, Comparable<ContainerPointer>

public interface ContainerPointer
extends Comparable<ContainerPointer>, Cloneable

This interface allows you to iterate over the containers in a roaring bitmap.

Method Summary

Modifier and Type	Method and Description
void	advance() Move to the next container
ContainerPointer	clone() Create a copy
int	getCardinality() Return the cardinality of the current container
Container	getContainer() This method can be used to check whether there is current a valid container as it returns null when there is not.
boolean	isBitmapContainer() Check whether the current container is a bitmap container.
boolean	isRunContainer() Check whether the current container is a run container.
short	key() The key is a 16-bit integer that indicates the position of the container in the roaring bitmap.
