Method Detail

createInstrumenters

public List<Instrumenter> createInstrumenters()
                                       throws EngineException

Initialises script engine instrumentation.

Each script engine can provide instrumenters, irrespective of the engine used to execute the script. The instrumenters provided by each engine are consulted according to service registration order in the META-INF file.

Specified by:

createInstrumenters in interface ScriptEngineService

Returns:

Additional instrumenters to use. Engines that do not provide instrumentation should return an empty list.

Throws:

EngineException - If a problem occurred creating instrumenters.

createScriptEngine

public ScriptEngineService.ScriptEngine createScriptEngine(ScriptLocation script)
                                                    throws EngineException

If the script engine service can handle the given script, it should return a suitable implementation.

Implementations typically will execute the script and perform any process level initialisation.

Specified by:

createScriptEngine in interface ScriptEngineService

Parameters:

script - The script.

Returns:

The script engine, or null.

Throws:

EngineException - If an implementation could not be created.
