Class WrappedConciseBitmap

java.lang.Object
org.apache.druid.collections.bitmap.WrappedConciseBitmap
All Implemented Interfaces:
ImmutableBitmap, MutableBitmap
public class WrappedConciseBitmap extends Object implements MutableBitmap

  • Constructor Details

    • WrappedConciseBitmap

      public WrappedConciseBitmap()
      Create a new WrappedConciseBitmap wrapping an empty ConciseSet

    • WrappedConciseBitmap

      public WrappedConciseBitmap(ConciseSet conciseSet)
      Create a bitmap wrapping the given bitmap
      Parameters:
      conciseSet - bitmap to be wrapped

  • Method Details

    • getBitmap

      public ConciseSet getBitmap()

    • toBytes

      public byte[] toBytes()
      Specified by:
      toBytes in interface ImmutableBitmap

    • clear

      public void clear()
      Description copied from interface: MutableBitmap
      Empties the content of this bitmap.
      Specified by:
      clear in interface MutableBitmap

    • or

      public void or(MutableBitmap mutableBitmap)
      Description copied from interface: MutableBitmap
      Compute the bitwise-or of this bitmap with another bitmap. The current bitmap is modified whereas the other bitmap is left intact. Note that the other bitmap should be of the same class instance.
      Specified by:
      or in interface MutableBitmap
      Parameters:
      mutableBitmap - other bitmap

    • getSizeInBytes

      public int getSizeInBytes()
      Description copied from interface: MutableBitmap
      Return the size in bytes for the purpose of serialization to a ByteBuffer. Note that this is distinct from the memory usage.
      Specified by:
      getSizeInBytes in interface MutableBitmap
      Returns:
      the total set in bytes

    • add

      public void add(int entry)
      Description copied from interface: MutableBitmap
      Add the specified integer to the bitmap. This is equivalent to setting the ith bit to the value 1.
      Specified by:
      add in interface MutableBitmap
      Parameters:
      entry - integer to be added

    • size

      public int size()
      Specified by:
      size in interface ImmutableBitmap
      Returns:
      The number of bits set to true in this bitmap

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • remove

      public void remove(int entry)
      Description copied from interface: MutableBitmap
      Remove the specified integer to the bitmap. This is equivalent to setting the ith bit to the value 1.
      Specified by:
      remove in interface MutableBitmap
      Parameters:
      entry - integer to be remove

    • iterator

      public org.roaringbitmap.IntIterator iterator()
      Specified by:
      iterator in interface ImmutableBitmap
      Returns:
      an iterator over the set bits of this bitmap

    • peekableIterator

      public org.roaringbitmap.PeekableIntIterator peekableIterator()
      Specified by:
      peekableIterator in interface ImmutableBitmap
      Returns:
      a peekable iterator which can skip to a position

    • isEmpty

      public boolean isEmpty()
      Specified by:
      isEmpty in interface ImmutableBitmap
      Returns:
      True if this bitmap is empty (contains no set bit)

    • intersection

      public ImmutableBitmap intersection(ImmutableBitmap otherBitmap)
      Description copied from interface: ImmutableBitmap
      Compute the bitwise-and of this bitmap with another bitmap. A new bitmap is generated. Note that the other bitmap should be of the same class instance.
      Specified by:
      intersection in interface ImmutableBitmap
      Parameters:
      otherBitmap - other bitmap

    • union

      public ImmutableBitmap union(ImmutableBitmap otherBitmap)
      Description copied from interface: ImmutableBitmap
      Compute the bitwise-or of this bitmap with another bitmap. A new bitmap is generated. Note that the other bitmap should be of the same class instance.
      Specified by:
      union in interface ImmutableBitmap
      Parameters:
      otherBitmap - other bitmap

    • get

      public boolean get(int value)
      Description copied from interface: ImmutableBitmap
      Returns true if the bit at position value is set
      Specified by:
      get in interface ImmutableBitmap
      Parameters:
      value - the position to check
      Returns:
      true if bit is set
