WrappedImmutableRoaringBitmap

public WrappedImmutableRoaringBitmap(org.roaringbitmap.buffer.ImmutableRoaringBitmap immutableRoaringBitmap)

Wrap an ImmutableRoaringBitmap

Parameters:

immutableRoaringBitmap - bitmap to be wrapped

Method Detail

getBitmap

public org.roaringbitmap.buffer.ImmutableRoaringBitmap getBitmap()

toBytes

public byte[] toBytes()

Specified by:

toBytes in interface ImmutableBitmap

toString

public String toString()

Overrides:

toString in class Object

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

batchIterator

public org.roaringbitmap.BatchIterator batchIterator()

Specified by:

batchIterator in interface ImmutableBitmap

Returns:

a batched iterator over the set bits of this bitmap

size

public int size()

Specified by:

size in interface ImmutableBitmap

Returns:

The number of bits set to true in this bitmap

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface ImmutableBitmap

Returns:

True if this bitmap is empty (contains no set bit)

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

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
