Method Detail

clone

PointableRoaringArray clone()

Create an independent copy of the underlying array

Returns:

a copy

getContainer

MappeableContainer getContainer(short x)

Parameters:

x - 16-bit key

Returns:

matching container

getContainerAtIndex

MappeableContainer getContainerAtIndex(int i)

Parameters:

i - index

Returns:

matching container

getContainerPointer

org.roaringbitmap.buffer.MappeableContainerPointer getContainerPointer()

Returns:

a ContainerPointer to iterator over the array

getIndex

int getIndex(short x)

Parameters:

x - 16-bit key

Returns:

corresponding index

getKeyAtIndex

short getKeyAtIndex(int i)

Parameters:

i - the index

Returns:

16-bit key at the index

size

int size()

Returns:

number of keys

serialize

void serialize(DataOutput out)
        throws IOException

Serialize. The current bitmap is not modified.

Parameters:

out - the DataOutput stream

Throws:

IOException - Signals that an I/O exception has occurred.

serializedSizeInBytes

int serializedSizeInBytes()

Returns:

the size that the data structure occupies on disk
