Direct Known Subclasses:

DeserializerImpl, LibraryBuilder, SerializerImpl

public abstract class BerEncoding
extends java.lang.Object

Class for efficient integer representation. A BER encoded integer is represented as a variable length sequence of bytes, in network-byte order, with 7 bits of data, and the topmost bit representing a "continue" flag. If set, another byte follows. This allows numbers in the range 0-127 to be represented with one byte, 128-16384 in two bytes, etc.
