ByteSpec (lisp.common.type.ByteSpec)

A byte specifier is an object that stores which bits of an array of bits the given byte manipulation will be applied to. Contains the factory method needed to create ByteSpec objects. The newInstance method has the following signatures: newInstance(java.common.type.Integer size, java.common.type.Integer position).
