Interface ScriptEngineCallback

public interface ScriptEngineCallback

An object of this class is granted by the System to all Script Service implementations, see ScriptService.init(ScriptEngineCallback) to provide them callback interface to push back results for asynchronous executions an to get additional context information whenever its needed.

Method Summary

Modifier and Type	Method and Description
AsyncResult	getAsyncResult(java.lang.String id) Restores AsyncResult object by given id.
ExecutionContext	getExecutionContext() Retrieves addition execution context information by the System.

Method Detail

getAsyncResult

AsyncResult getAsyncResult(java.lang.String id)

Restores AsyncResult object by given id. AsyncResult-s are used by asynchronous Script Service methods whenever they wish to complete the real action execution asynchronously in background, see ScriptService. AsyncResult objects have id-s, see AsyncResult.getId() allowing the Script Service to not keep temporarily the AsyncResult object until execution is complete, but to restore the objects via the system callback.

Parameters:

id - id of the AsyncResult object.

Returns:

restored AsyncResult object.

getExecutionContext

ExecutionContext getExecutionContext()

Retrieves addition execution context information by the System. For instance, called within the body of a Script Service method (see ScriptService), the ExecutionContext may provide information on which concreted managed device the script (producing the method call) is executed.

Returns:

execution context.
