Examples of org.apache.bsf.BSFEngine

org.apache.bsf.BSFEngine
This is the view of a scripting engine assumed by the Bean Scripting Framework. This interface is used when an application decides to run some script under application control. (This is the reverse of the more common situation, which is that of the scripting language calling into the application.)
When a scripting engine is first fired up, the initialize() method is called right after construction.
A scripting engine must provide two access points for applications to call into them: via function calls and via expression evaluation. It must also support loading scripts.
A scripting engine is a property change listener and will be notified when any of the relevant properties of the manager change. (See BSFManager to see which of its properties are bound.) @author Sanjiva Weerawarana @author Matthew J. Duftler
