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

getCardinality

int getCardinality(int i)

Returns the cardinality of the container at the given index. This method is expected to be fast.

Parameters:

i - index

Returns:

the cardinality
