 boolean debug,
 PrintStream ps)

Deprecated.

use create(Class, boolean, PrintStream)

Construct a generator for a proxy class that implements the given interfaces and extends superClass. superClass must satisfy the following requirements:

1. It must have an accessible no args constructor
2. It must have a method satisfying the signature Object invoke( int methodNumber, Object[] args ) throws Throwable
3. The invoke method described above must be accessible to the generated class (generally either public or protected.

Each method in methods is implemented by a method that:

1. Creates an array sized to hold the args
2. Wraps args of primitive type in the appropriate wrapper.
3. Copies each arg or wrapper arg into the array.
4. Calls invoke with a method number corresponding to the index of the method in methods. Note that the invoke implementation must use the same method array to figure out which method has been invoked.
5. Return the result (if any), extracting values from wrappers as needed to handle a return value of a primitive type.

Note that the generated methods ignore exceptions. It is assumed that the invoke method may throw any desired exception.

Parameters:

pd - the protection domain of the generated class

cl - the classloader in which to generate the class

debug - if true, generate debug messages

ps - a PrintStream to which the debug messages should be written

Returns:

Generator for class

Note that the generated methods ignore exceptions. It is assumed that the invoke method may throw any desired exception.

Parameters:

anchorClass - a class in whose classloader the new class should be generated

debug - if true, generate debug messages

ps - a PrintStream to which the debug messages should be written

Returns:

Generator for class
