Examples of Mediator

com.l2client.animsystem.Mediator
The Mediator is used to glue the different animation system parts together. At startup it is fed with a subset of actions and transitions to be used by that entity (several could have the same configuration, some could be different). The external system should use some methods to provide data for animation system updates. The methods setAnimationProvider(..), update(..), setInput(..), callAction(..) and the constructor should be used by a calling system. Animationsystem based on Game AI Wisdom 2 Animation Selection by Chris Heckers Provided here is an animation system which allows control of multi channel animations by means of simple actions and input values. Transitions between animations are also supported. It is not an animation library. The animation system sits on top af any lower level implementation and directing the execution of such a low level system. Currently a JMonkeyengine 2 implementation is provided as an example. The system comprises of different components working together to achieve the desired animation selection. @see Channel The animation system was designed for multi channel animations. For example you could differentiate between upper body, lower body, left arm, right arm, etc. If you would need different channels tha the ones provided, the change Channel.java A Channel holds a lock for a level for a set time where no other animation of the same level can overide the lock easily. Input The whole system is driven by read only Input variables, they are nothing more than enumerations. @see InputProvider is a storage component to be used between an application and the animation system to exchange input values for an entity. The input Values you need would be implmented by creating your enums for input constants and adding feeding them to the animation system. The first value of the enum should be the initial/default value. @see Action Actions are the place where the whole selection takes place. An actions tries to get a lock on a channel and if gained is allowed to fill an animation system owned animation descriptor. Normally a default action is used and several other animation actions are provided for more important animations or completely different selection algorithms. New Actions should be based on Action.java and only override the evaluate(..) method. Transitions The concept describes transitions to be based on input value changes by actions. My implementation uses plain animations, so if you would be in need of a more sophisticated transition selection system you should change the Transitions.java implementation, or overide it. IAnimationProvider, Mediator IAnimationProvider.java is used to bridge the low level implementation with the animation system. It is here where the low level animation should be set, where low level internal animations are created/looked up/loaded on demand/fetched and provide information like the animation length. The Mediator is used to glue the different animation system parts together. At startup it is fed with a subset of actions and transitions to be used by that entity (several could have the same configuration, some could be different). The external system should use some methods to provide data for animation system updates. The methods setAnimationProvider(..), update(..), setInput(..), callAction(..) and the constructor should be used by a calling system. Building your own animation system configuration. -Decide which channels you need, if you need more than are provided in Channel.java, then change that class (normally should contain just any channels you would need). Perhaps you need a more sophisticated channel configuration, if not, leave it in place. -Decide on the input values which should be driving your actions. For each input type create an enum so it can be used in your engine code to fill an InputProvider and used by the actions to look at the current inpt state. -Decide on the actions you need. Normally you have some idle animation. This one would be the default action used on each frame (functioning like a fallback) other actions you need would be priorized by selecting a certian lock level. An idle normally is the lowest priority, so we give it a lock level of 0, a taunt, or walk could be 1, an attack could try to lock on even higher, a hurt action would be even higher (no matter what we normally act very fast to being hurt..). Implement your actions by overridng Action.java. The actions do mostly the same, try to get a lock, decide on which animation name to choose and which parameters to be passed on to the low level system (looping, playbackrate, etc.) -Decide on the transitions you would need for your system. Give it a try by specifying them by using current animation name, final animation name, transition animation. Should be sufficient for most configurations. -Implement a position in your engine where update calls can be received on each frame, the input hooks are routed to the mediator and the animationprovider information is filled out. Have a look at the JMEAnimationController for inspiration. Building an animation system for JMonkeyengine 2 To give you some hints on how to integrate the animation system into your engine an example is provided based on the JMonkeyengine 2, the code can be found in the library folder src/../animsystem/example/. As a starting point we will look at the ninja ogre model comming with jmonkey. The model comes with the following animations: Attack1, Attack2, Attack3, Backflip, Block, Climb, Crouch, Death1, Death2, HighJump, Idle1, Idle2, Idle3, Jump, JumpNoHeight, Kick, SideKick, Spin, Stealth, Walk. All animations are full body animations, as they provide values for all joints. But it could be also the case that attacks and idle affect the uper body only and the walk the lower body. We will create such a system just to show you how to set it up, although the model is not ready to be using the different channels. So we will have three channels, AllChannels, Upper and Lowerbody. Well better not, you can test this by changing the channels in some actions, but you will notice that the Ninja animations will look jerkey as they might get replaced by default animations at any time inbetween. So I left it out. The system will be based on the following input values which will be created as enums: Movement=None,Walking; AttackType=None,Weapon; Acting=Open,Hidden; Target=None,Mid,High,Back. The available actions should be default, attack, defend, climb, jump, die. Default will somehow result in Idle1-3, Stealth, Walk, Crouch animations. Attack will deliver the Attack1-3, Kicks and Spin animations. Defend logically only a Block, Climb a climb animation. The jump action will result in any jump related animations. Having decided what actions there should be it is now the time to think about the locklevels/priorities of the animations. Basically the idle stuff comes at the lowest level so we give it a zero (0). An attack should be higher, but how much? Should it be possible to attack while in a jump? If so it should be higher, than a jump. So we give jump a one (1) and attack a two (2). Defend is the same as an attack but the revers, so we give it also a two(2). A jump is similar to a climb, in my system I would like to be able to interrup any climb by an atack or defend, so I give the climb also a locklevel of one (1). Death of course is one of the top priorities, if you are dead it should be instant, right? So we give it the highest priority, three (3) as it should be possible to drop an attack animation or whatever and start to play the death animation. Remember this was just my interpretation of what should be able to cancel what out. The choice could be completely different in your situation. Finally the actions are implemented, requesting a lock, filling out an animation bean with information. In the current scenario there are no transitions. That's ok too. Or you could create animations which perhaps speed up from an idle before starting to full run. To implement the location in the engine we would extend the Ogre MeshAnimationController with the needed methods and interfaces. In addition the entity class will be extended with a possibility to collect input values and pass them on to the controller. Direct actions calls should also be implemented, which is a different building block (on a playable character this would go into input wireing, on an entity into its entity AI code). In the demonstration the input passing is simulated by a gui interface. Why do the animations sometimes look jerkey? From what I can guess the example jme ninja animations are not animated well, the walk cycle for example look smooth, the hidden_idel not. So I guess it's just the quality of animations that counts.
jmt.gui.jmodel.controller.Mediator
This class mantains a reference to all the main copmponents of the Gui, in this way it's possible to divide the responsability of the actions & every object know only about of himself & the mediator. Other actions are made through the mediator without knowing who will actually do it. @author Federico GranataDate: 3-giu-2003 Time: 16.54.45 Heavily modified by Bertoli Marco 2-giu-2005 Modified by Francesco D'Aquino Modyfied by Bertoli Marco to support JGraph 5.8 - 21/mar/2006 Modified by Giuseppe De Cicco & Fabio Granara @author Ashanka Date: 11March 2010Description: Added a logic to remove the duplicate name of the files from displaying. Modified by Ashanka (May 2010): Patch: Multi-Sink Perf. Index Description: Added new Performance index for the capturing the 1. global response time (ResponseTime per Sink) 2. global throughput (Throughput per Sink) each sink per class. Model validation of the perf indices.
ke.go.moh.oec.lib.Mediator
Mediator between OEC clients and services to forward requests and return responses. This may include storing and forwarding requests and/or responses when network connections cannot be made.
If the user of this class accepts unsolicited messages (as a server), then it must register a callback object that is compliant with the IService interface. If the user of this class is just making client requests, this is not necessary. @author JGitahi @author Jim Grace
org.aavso.tools.vstar.ui.mediator.Mediator
This class manages the creation of models and views and sends notifications for changes to mode and analysis types. This is a Singleton since only one mediator per application instance should exist. TODO: This is really 2 classes: a task manager and a message broker...
org.apache.synapse.Mediator
All Synapse mediators must implement this Mediator interface. As a message passes through the Synapse system, each mediator's mediate() method is invoked in the sequence/order defined in the SynapseConfiguration.

It is recommended to extend the abstract class {@link org.apache.synapse.mediators.AbstractMediator} or the{@link org.apache.synapse.mediators.AbstractListMediator} as appropriate instead ofdirectly implementing this interface @see org.apache.synapse.mediators.AbstractMediator
org.apache.synapse.api.Mediator
All Synapse mediators must implement this Mediator interface. As a message passes through the synapse system, each mediator's mediate() method is invoked in the sequence/order defined in the SynapseConfiguration.

org.eclipse.sisu.Mediator
@Named for automatic registration public class MyMediator implements Mediator<Named, MyType, MyWatcher> { public void add( BeanEntry<Named, MyType> entry, MyWatcher watcher ) throws Exception { // translate event to whatever the watcher expects } public void remove( BeanEntry<Named, MyType> entry, MyWatcher watcher ) throws Exception { // translate event to whatever the watcher expects } } Mediator implementations must have a public no-arg constructor; they are neither injected nor injectable, acting instead as stateless translators.

IMPORTANT: mediation occurs when bindings change and there is at least one live watcher. If no-one requests or injects an instance of the watcher type then the mediator will not be called.

In the following example as soon as MyTabbedPane is injected, Sisu will use the SwingTabMediator to deliver all known JPanels annotated with @Tab to the watching MyTabbedPane. Sisu will continue to send updates, which add or remove tabs as appropriate, until the MyTabbedPane instance becomes unreachable. MyTabbedPane doesn't need to know anything about Sisu APIs and vice-versa because SwingTabMediator takes care of the necessary translation.
```
 @Named public class MyTabbedPane extends JTabbedPane { // watcher } @Qualifier @Retention( RetentionPolicy.RUNTIME ) public @interface Tab { String title(); } @Tab( title = "Summary" ) public class SummaryTab extends JPanel { // qualified bean } @Tab( title = "Notes" ) public class NotesTab extends JPanel { // qualified bean } @Named public class SwingTabMediator implements Mediator<Tab, JPanel, MyTabbedPane> { public void add( BeanEntry<Tab, JPanel> entry, final MyTabbedPane watcher ) throws Exception { final Tab tab = entry.getKey(); final JPanel panel = entry.getValue(); SwingUtilities.invokeLater( new Runnable() { public void run() { watcher.addTab( tab.title(), panel ); } } ); } public void remove( BeanEntry<Tab, JPanel> entry, final MyTabbedPane watcher ) throws Exception { final Tab tab = entry.getKey(); SwingUtilities.invokeLater( new Runnable() { public void run() { watcher.removeTabAt( watcher.indexOfTab( tab.title() ) ); } } ); } }
