All Superinterfaces:

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.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	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.
`char`	`key()`	The key is a 16-bit integer that indicates the position of the container in the roaring bitmap.

    Returns:
    
    return a clone of this pointer
  - getCardinality
```
int getCardinality()
```
    Return the cardinality of the current container
    
    Returns:
    
    the cardinality
  - getContainer
```
Container getContainer()
```
    This method can be used to check whether there is current a valid container as it returns null when there is not.
    
    Returns:
    
    null or the current container
  - isBitmapContainer
```
boolean isBitmapContainer()
```
    Check whether the current container is a bitmap container.
    
    Returns:
    
    whether it is a bitmap container
  - isRunContainer
```
boolean isRunContainer()
```
    Check whether the current container is a run container.
    
    Returns:
    
    whether it is a run container
  - key
```
char key()
```
    The key is a 16-bit integer that indicates the position of the container in the roaring bitmap. To be interpreted as an unsigned integer.
    
    Returns:
    
    the key
