getCoder

public Codec.Binary.Coder getCoder(it.unimi.dsi.fastutil.longs.Long2LongMap frequencies)

Description copied from interface: Codec

Returns a coder for a specific map from symbols to frequencies.

Note that even instantaneous codes (such as Codec.Unary) need to know the set of symbols, as the returned coder needs to known the maximum codeword length.

Specified by:

getCoder in interface Codec

Parameters:

frequencies - a map from symbols (longs) to frequencies (longs).

Returns:

a coder for the given map.
