接口 ContainerPointer

所有超级接口:

Cloneable, Comparable<ContainerPointer>

public interface ContainerPointer
extends Comparable<ContainerPointer>, Cloneable

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

方法概要

修饰符和类型	方法	说明
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.
char	key()	The key is a 16-bit integer that indicates the position of the container in the roaring bitmap.
