Interface MethodMissing

public interface MethodMissing

Implemented by Script Services that wish to provide dynamic methods functionality. Dynamic methods are methods that are note statically defined in the java interface, but are defined at runtime, possibly depending on the interface with the underlying managed resource. For instance if my device is runtime detected as a lamp there could be dynamically provided methods siwtchOn() and switchOff(), but if my device is a door then my dynamic methods would be open() and close().

Script Services wishing to provide such dynamic functionality for their objects must make them implement this interface. Dynamic methods are handled via the common methods:

methodMissing(String, Object) - for synchronous dynamic methods methodMissing(String, Object, AsyncResult) - for asynchronous methods. where the methodName argument specifies the method name given within the launched script and args argument bring the supplied via the launched script arguments.

In addition, there is the script services should provide dynamic metadata via the methodMissingMetaData(String, Object) to tell the system how given dynamic method should be treated - synchronously or asynchronously and whether its execution should or should not be reported to the user as a partial execution result, i.e., if the method execution should reflect into dedicated DeviceExecItem on the fron-end.
