所有超级接口:
Cloneable, Comparable<MappeableContainerPointer>
public interface MappeableContainerPointer extends Comparable<MappeableContainerPointer>, Cloneable
This interface allows you to iterate over the containers in a roaring bitmap.

  • 方法概要

    方法
    说明
    void
    advance()
    Move to the next container
    MappeableContainerPointer
    clone()
    Create a copy
    int
    getCardinality()
    Returns the cardinality of the current container.
    MappeableContainer
    getContainer()
    This method can be used to check whether there is current a valid container as it returns null when there is not.
    int
    getSizeInBytes()
    Get the size in bytes of the container.
    boolean
    hasContainer()
     
    boolean
    isBitmapContainer()
    Returns true if it is a bitmap container (MappeableBitmapContainer).
    boolean
    isRunContainer()
    Returns true if it is a run container (MappeableRunContainer).
    char
    key()
    The key is a 16-bit integer that indicates the position of the container in the roaring bitmap.
    void
    previous()
    Move to the previous container

    • advance

      void advance()
      Move to the next container

    • clone

      MappeableContainerPointer clone()
      Create a copy
      返回:
      return a clone of this pointer

    • getCardinality

      int getCardinality()
      Returns the cardinality of the current container. Can be faster than loading the container first.
      返回:
      cardinality of the current container

    • getContainer

      MappeableContainer getContainer()
      This method can be used to check whether there is current a valid container as it returns null when there is not.
      返回:
      null or the current container

    • getSizeInBytes

      int getSizeInBytes()
      Get the size in bytes of the container. Used for sorting.
      返回:
      the size in bytes

    • hasContainer

      boolean hasContainer()
      返回:
      whether there is a container at the current position

    • isBitmapContainer

      boolean isBitmapContainer()
      Returns true if it is a bitmap container (MappeableBitmapContainer).
      返回:
      boolean indicated if it is a bitmap container

    • isRunContainer

      boolean isRunContainer()
      Returns true if it is a run container (MappeableRunContainer).
      返回:
      boolean indicated if 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.
      返回:
      the key

    • previous

      void previous()
      Move to the previous container
