public CodeException(CodeException c)
- Initialize from another object.
CodeException
public CodeException(int start_pc,
int end_pc,
int handler_pc,
int catch_type)
- Parameters:
start_pc
- Range in the code the exception handler is active,

- is exclusivehandler_pc
- Starting address of exception handler, i.e.
an offset from start of code.catch_type
- If zero the handler catches any
exception, otherwise it points to the exception class which is
to be caught.
