Interface SlingScript

public interface SlingScript

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

Objects implementing this interface are returned by the SlingScriptResolver.findScript(org.apache.sling.api.resource.ResourceResolver, String) method.
