Class ClassParser
public final
class
ClassParser
extends Object
Wrapper class that parses a given Java .class file. The method
parse returns a
JavaClass object on success. When an I/O error or an
inconsistency occurs an appropiate exception is propagated back to
the caller.
The structure and the names comply, except for a few conveniences,
exactly with the
JVM specification 1.0. See this paper for
further details about the structure of a bytecode file.
