pentaho.action Base
The action.Base class represents a certain model of actions.
Synchronous or Asynchronous
An action can be synchronous or asynchronous, as determined by the type property, pentaho.action.Base.isSync. The execution of a synchronous action is completed synchronously, while that of an asynchronous action only completes asynchronously.
Execution
Actions are executed at and by target objects, which implement the interface ITarget, by being passed as the argument to the ITarget#act method.
Targets control the exact implementation of the execution of an action, which is returned from the act method, in the form of an Execution. However, it is the action that imposes whether execution is synchronous or not, and the phases by which execution goes through, which are, for all action types:
- "init" - the execution is being initialized and a chance is given to mutate the action and change what will be done;
- "will" - action is now frozen and the action can be canceled based on what will be done;
- "do" - the action is executed;
- "finally" - the action execution has finished successfully or not.
For more information, see Execution.

Base
The Scene class represents one distinct visual state which is represented visually by one or more visual elements.
Scenes are not needed to implement visualization views. However, their use simplifies their implementation in many use cases.
Scenes have a map of visual variables, vars whose values are inherited from parent to child scenes.
To create scenes, most view implementations can simply use the [scene.Base.buildScenesFlat] method. This method creates one parent scene having one child scene per row of the model's dataset. In child scenes, for each visual role there will be a correspondingly named variable having the value of the visual role.
For handling user interaction, the scene instances' createFilter method provides an easy way to create a filter that selects the data from which the scene was generated based on its distinguishing field values. This filter can then be passed to a data action such as Select or Execute.
When communicating with external parties, field values must be used and visual variable values are not generally meaningful. The invert method allows directly obtaining the distinguishing field values that are associated with a scene.
