Method

Einvoke(Object target, String methodName, Object... args)
invoke 
for (Method method : target.getClass().getMethods()) {
    if (method.getName().equals(methodName)) {
        try {
            return (E) method.invoke(target, args);
        } catch (Exception e) {
            throw new RuntimeException("Exception invoking method " + methodName, e);
throw new RuntimeException("Method " + methodName + " not found");
Objectinvoke(Object target, String methodName, Object[] args)
invoke 
try {
    Class<? extends Object> clazz = target.getClass();
    Method method = findMethod(clazz, methodName, args);
    method.setAccessible(true);
    return method.invoke(target, args);
} catch (Exception e) {
    throw new RuntimeException("couldn't invoke " + methodName + " on " + target, e);
Objectinvoke(Object target, String name, Class[] params, Object[] args)
Returns the result of invoking the method name on target with parameters params declared in the target's class using arguments args. 
return invoke(target.getClass(), target, name, params, args);
Objectinvoke(Object targetObject, String method, Class[] paramTypes, Object[] paramValues)
invoke 
String methodKey = getMethodKey(targetObject.getClass(), method, paramTypes);
Method methodObject = METHOD_CACHE.get(methodKey);
if (methodObject == null) {
    methodObject = targetObject.getClass().getMethod(method, paramTypes);
    if (methodObject != null) {
        METHOD_CACHE.put(methodKey, methodObject);
return methodObject.invoke(targetObject, paramValues);
Objectinvoke(Object targetObject, String methodName, Object... params)
invoke 
return findMethod(targetObject.getClass(), methodName, params).invoke(targetObject, params);
Tinvoke(Object thisObject, Method method)
invoke 
return (T) method.invoke(thisObject, NO_PARAM_SIGNATURE);
Objectinvoke(ObjectName objectName, Object[] params, String[] signature, String operationName)
invoke
