Class Mangling

  • public class Mangling
extends java.lang.Object
    Helper methods for mangling and demangling. "Mangling" is converting a user-level identifier to an internal system-level name, which may be restricted in allowed characters. "Demangling" is the inverse operation.

                                              boolean force)
        Mangle according to John Rose's "Symbolic Freedom in the VM". See this article.
        Parameters:
        context - One of 'C' (class name); 'Q' (qualified name, with dots); 'F' (field name); 'M' (method name); 'V' (local variable name).
        force - True if should escape '\\' even if that is the only disallowed character. The may cause an already-mangled name to be doubly mangled.
