Interface SlingScript

public interface SlingScript

The SlingScript defines the API for objects which encapsulate a script. To evaluate a script prepare a SlingBindings instance of variables used as global variables to the script and call the eval(SlingBindings) method.

You can obtain scripts by resolving a script resource through ResourceResolver.resolve(String) and then trying to adapt the resource to a script by calling Adaptable.adaptTo(Class).
