Class Mangling

java.lang.Object

gnu.expr.Mangling

public class Mangling
extends 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.

Method Details

mangleClassName

public static String mangleClassName(String name)

Mangle a simple class or package name. Does not handle qualified names.

mangleQualifiedName

public static String mangleQualifiedName(String name)

Mangle a possibly-qualified class name.

mangleVariable

public static String mangleVariable(String name)

mangleField

public static String mangleField(String name)

demangleField

public static String demangleField(String name)

mangleMethod

public static String mangleMethod(String name)

demangleMethod

public static String demangleMethod(String name)

demangleQualifiedName

public static String demangleQualifiedName(String name)

mangleSymbolic

public static String mangleSymbolic(String name,
 char context,
 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.

demangleName

public static String demangleName(String name,
 boolean reversible)

demangle2

public static char demangle2(char char1,
 char char2)

Demangle a three-character mangling starting with '$'. UNFINISHED!

demangleSymbolic

public static String demangleSymbolic(String name)

mangleName

public static String mangleName(String name)

mangleName

public static String mangleName(String name,
 boolean reversible)

Convert a string to a safe Java identifier.

Parameters:

reversible - if we should use an invertible mapping.

mangleNameIfNeeded

public static String mangleNameIfNeeded(String name)
