Method Detail

getProfiledObject

public static Object getProfiledObject(Class interfaceClazz,
                       Object o)

Deprecated.

Given a class, and an interface that it implements, return a proxied version of the class that implements the interface.

The usual use of this is to profile methods from Factory objects:

 public PersistenceManager getPersistenceManager()
 {
   return new DefaultPersistenceManager();
 }

 instead write:
 public PersistenceManager getPersistenceManager()
 {
   return ObjectProfiler.getProfiledObject(PersistenceManager.class, new DefaultPersistenceManager());
 }
 

A side effect of this is that you will no longer be able to downcast to DefaultPersistenceManager. This is probably a *good* thing.

Parameters:

interfaceClazz - The interface to implement.

o - The object to proxy

Returns:

A proxied object, or the input object if the interfaceClazz wasn't an interface.

profiledInvoke

public static Object profiledInvoke(Method target,
                    Object value,
                    Object[] args)
                             throws IllegalAccessException,
                                    InvocationTargetException

Deprecated.

A profiled call Method.invoke(java.lang.Object, java.lang.Object[]). If UtilTimerStack.isActive() returns false, then no profiling is performed.

Parameters:

target - target method

value - value

args - arguments

Returns:

target object

Throws:

IllegalAccessException - in case of access errors

InvocationTargetException - in case of invocation errors

getTrimmedClassName

public static String getTrimmedClassName(Method method)

Deprecated.

Given a method, get the Method name, with no package information.

Parameters:

method - method

Returns:

method name, with no package information
