org.openjdk.asmtools.jasm.Environment

public class Environment
extends Object

An input stream for java programs. The stream treats either "\n", "\r" or "\r\n" as the end of a line, it always returns \n. It also parses UNICODE characters expressed as ￿. However, if it sees "\\", the second slash cannot begin a unicode sequence. It keeps track of the current position in the input stream. An position consists of: ((linenr << OFFSETBITS) | offset) this means that both the line number and the exact offset into the file are encoded in each position value.
