Interface IHuffConstants

All Known Subinterfaces:

IHuffProcessor

All Known Implementing Classes:

SimpleHuffProcessor

public interface IHuffConstants

Global constants used in Huff/Unhuff. Clients needing these values should implement this interface or access the values directly, e.g., as IHuffConstants.BITS_PER_WORD. However, implementing the interface is preferred in which case the values can be accessed simply as BITS_PER_WORD, for example.

Field Summary

static int	ALPH_SIZE The size of the alphabet given the number of bits per chunk, this should be 2^BITS_PER_WORD.
static int	BITS_PER_INT The standard number of bits needed to represent/store an int, this is 32 in Java and nearly all other languages.
static int	BITS_PER_WORD The standard number of bits per chunk/word when huffing.
static int	MAGIC_NUMBER Isolate the magic numbers in one place.
static int	PSEUDO_EOF The value of the PSEUDO_EOF character.
static int	STORE_COUNTS
static int	STORE_CUSTOM
static int	STORE_TREE
