Bite-sized byte-biting

Bite

Micro utility library for doing bit-fiddling in Java.

The name "bite" is a mixture of the words "bit" and "byte", and also refers to the fact that the library itself is "bite-sized" and involves biting bit patterns into submission.

The library is made mostly as a recreational exercise and may or may not have any real usages.

Functions

The Java Language Specification defines the following four primitive integer types:

Type	Width
byte	1 byte (8 bits)
short	2 bytes (16 bits)
int	4 bytes (32 bits)
long	8 bytes (64 bits)

In bite, there's a utility class for each of these types that contains functions for composing values into wider types, slicing them into narrower ones, overwriting sections of their bit pattern, etc.

Indexing

All indices are zero-based and increments from right to left.

The same rule applies when a value is interpreted as a composition of narrower ones. E.g., an int interpreted as four bytes, the zeroth byte is the right-most one etc.

Status

The library has no known bugs, but is also not very well tested.

It would also make sense to implement more common patterns.
