  - or
```
public void or(MutableBitmap mutableBitmap)
```
    Description copied from interface: MutableBitmap

    Specified by:
    
    or in interface MutableBitmap
    
    Parameters:
    
    mutableBitmap - other bitmap
  - and
```
public void and(MutableBitmap mutableBitmap)
```
    Description copied from interface: MutableBitmap
    
    Compute the bitwise-and 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:
    
    and in interface MutableBitmap
    
    Parameters:
    
    mutableBitmap - other bitmap
  - andNot
```
public void andNot(MutableBitmap mutableBitmap)
```
    Description copied from interface: MutableBitmap
    
    Compute the bitwise-andNot 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:
    
    andNot in interface MutableBitmap
    
    Parameters:
    
    mutableBitmap - other bitmap
  - xor
```
public void xor(MutableBitmap mutableBitmap)
```
    Description copied from interface: MutableBitmap
    
    Compute the bitwise-xor 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:
    
    xor 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
  - serialize
```
public void serialize(ByteBuffer buffer)
```
    Description copied from interface: MutableBitmap
    
    Write out a serialized (Immutable) version of the bitmap to the ByteBuffer. We preprend the serialized bitmap with a 4-byte int indicating the size in bytes. Thus getSizeInBytes() + 4 bytes are written. (These 4 bytes are required by ConciseSet but not by RoaringBitmap. Nevertheless, we always write them for the sake of simplicity, even if it wastes 4 bytes in some instances.)
    
    Specified by:
    
    serialize in interface MutableBitmap
    
    Parameters:
    
    buffer - where we write
  - 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
  - isEmpty
```
public boolean isEmpty()
```
    Specified by:
    
    isEmpty in interface ImmutableBitmap
    
    Returns:
    
    True if this bitmap is empty (contains no set bit)
  - 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
  - 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
  - difference
```
public ImmutableBitmap difference(ImmutableBitmap otherBitmap)
```
    Description copied from interface: ImmutableBitmap
    
    Compute the bitwise-andNot 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:
    
    difference 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
