With this example we are going to demonstrate how to get the ScriptEngine by name. The ScriptEngine interface is the fundamental interface whose methods must be fully functional in every implementation of this specification. These methods provide basic scripting functionality. Applications written to this simple interface are expected to work with minimal modifications in every implementation. It includes methods that execute scripts, and ones that set and get values. In short, to get the ScriptEngine by name you should:
- Create a new ScriptEngineManager. The ScriptEngineManager implements a discovery and instantiation mechanism for ScriptEngine classes and also maintains a collection of key/value pairs storing state shared by all engines created by the Manager.
- Use the
getEngineByName(String shortName)API method to look up and create a ScriptEngine for a given name.
- Then you can use the
eval(String script)method to execute a script.
Let’s take a look at the code snippet that follows:
