Method Detail

decode

int decode(it.unimi.dsi.fastutil.booleans.BooleanIterator iterator)

Decodes the next symbol from the given boolean iterator.

Note that InputBitStream implements BooleanIterator.

Parameters:

iterator - a boolean iterator.

Returns:

the next symbol decoded from the bits emitted by i

Throws:

NoSuchElementException - if iterator terminates before a symbol has been decoded.

decode

int decode(InputBitStream ibs)
           throws IOException

Decodes the next symbol from the given input bit stream.

Note that InputBitStream implements BooleanIterator.

Parameters:

ibs - an input bit stream.

Returns:

the next symbol decoded from ibs.

Throws:

IOException
