Strongly type Updater's perform conversions based on this the expected type before the bean update is invoked. since:    0.7 author:    Jakarta Commons Team, Apache Software Foundation Method Summary abstract protected  void executeUpdate(Context context, Object bean, Object value)      Updates the bean with the given value. public  Class getValueType()      Gets the type expected. protected  void handleException(Context context, Exception e)      Strategy method to allow derivations to handle exceptions differently. public  void setValueType(Class valueType)      Sets the type expected. public  void update(Context context, Object newValue)      Method Detail executeUpdate abstract protected void executeUpdate(Context context, Object bean, Object value) throws Exception(Code) Updates the bean with the given value. Parameters:   bean - Parameters:   value - value after type conversion getValueType public Class getValueType()(Code) Gets the type expected. The value passed into TypedUpdater.update will be converted on the basis of this type before being passed to TypedUpdater.executeUpdate . Class giving expected type, not null handleException protected void handleException(Context context, Exception e)(Code) Strategy method to allow derivations to handle exceptions differently. Parameters:   context - the Context being updated when this exception occured Parameters:   e - the Exception that occured during the update setValueType public void setValueType(Class valueType)(Code) Sets the type expected. The value passed into TypedUpdater.update will be converted on the basis of this type before being passed to TypedUpdater.executeUpdate . Parameters:   valueType - Class giving expected type, not null update public void update(Context context, Object newValue)(Code) Updates the current bean context with the given String value Parameters:   context - the Context to be updated Parameters:   newValue - the update to this new value Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
