Data::BitStream::Code::Omega - A Role implementing Elias Omega codes
A role written for Data::BitStream that provides get and set methods for the Elias Omega codes. The role applies to a stream object.
Provided Object Methods
Insert one or more values as Omega codes. Returns 1.
Decode one or more Omega codes from the stream. If count is omitted, one value will be read. If count is negative, values will be read until the end of the stream is reached. In scalar context it returns the last code read; in array context it returns an array of all codes read.
These methods are required for the role.
