Method Detail

loadClass

public static java.lang.Class loadClass(java.lang.ClassLoader loader,
                                        java.lang.String name)
                                 throws java.lang.ClassNotFoundException

This methods load a class given the classloader and the name of the class, and work for extended names of primitive types.

If you try to do ClassLoader.loadClass("boolean") it barfs it cannot find the class, so this method cope with this problem.

Throws:

java.lang.ClassNotFoundException

loadClasses

public static java.lang.Class[] loadClasses(java.lang.ClassLoader loader,
                                            java.lang.String[] names)
                                     throws java.lang.ClassNotFoundException

Returns the classes whose names are specified by the names argument, loaded with the specified classloader.

Throws:

java.lang.ClassNotFoundException

public static boolean isAttributeGetter(java.lang.reflect.Method m)

Returns true is the given method is a JMX attribute getter method

isAttributeSetter

public static boolean isAttributeSetter(java.lang.reflect.Method m)

Returns true if the method is a JMX attribute setter method

public static boolean wildcardMatch(java.lang.String pattern,
                                    java.lang.String string)
