接口 ContainerPointer

所有超级接口:

java.lang.Cloneable, java.lang.Comparable<ContainerPointer>

public interface ContainerPointer
extends java.lang.Comparable<ContainerPointer>, java.lang.Cloneable

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

方法概要

限定符和类型	方法和说明
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.
