This patch makes gjavah have the same behaviour as OpenJDK's javah
in producing header files for any inner classes found in the classes
being parsed.
ChangeLog:
2011-09-09 Andrew John Hughes <[email protected]>
PR classpath/45526: Produce header files for
any inner classes found.
* tools/gnu/classpath/tools/javah/Main.java:
(parsed): Set of class names that have been parsed.
(writeHeader(Map,Printer)): Take a general Map
rather than a specific HashMap.
(parseClasses(Iterator<Object>)): Factor out
the parsing of class files into a separate
method so it can be called recursively for
inner classes.
(getClass(String)): Remove redundant cast.
