public MethodDescriptor(Method method) 
{
        this(method, null);
}

Constructs a MethodDescriptor from a Method.

Parameters:

method - The low-level method information.

 MethodDescriptor(MethodDescriptor old) 
{
        super(old);
        methodRef = old.methodRef;
        params = old.params;
        paramNames = old.paramNames;
        if (old.parameterDescriptors != null) {
            int len = old.parameterDescriptors.length;
            parameterDescriptors = new ParameterDescriptor[len];
            for (int i = 0; i <  len ; i++) {
                parameterDescriptors[i] = new ParameterDescriptor(old.parameterDescriptors[i]);
            }
        }
}

    ParameterDescriptor[] parameterDescriptors) 
{
        setName(method.getName());
        setMethod(method);
        this.parameterDescriptors = parameterDescriptors;
}

Constructs a MethodDescriptor from a Method providing descriptive information for each of the method's parameters.

Parameters:

method - The low-level method information.

parameterDescriptors - Descriptive information for each of the method's parameters.
