Class JepInstance

java.lang.Object

com.feedzai.openml.python.jep.instance.JepInstance

All Implemented Interfaces:

Runnable

public class JepInstance
extends Object
implements Runnable

Wrapper for a Jep object that runs it on a separate dedicated thread. The thread will be on an infinite loop waiting for evaluations (AbstractJepEvaluation).

Method Detail

start

public void start()

Starts the thread and consequently the Jep instance inside it. Sets running to true signalling this instance is ready to receive evaluations.

stop

public void stop()

Sets running to false signalling the instance is no longer ready to receive evaluations. Interrupts the thread that should be on an infinite evaluation loop.

Implementation Note:

Currently this interrupt can catch an evaluation in which case it's future will never return.

run

public void run()

Runnable that will run on the instance thread. Creates a local Jep instance and enters an infinite read-eval loop doing evaluations (AbstractJepEvaluation).

Specified by:

run in interface Runnable

submitEvaluation

public <T> AbstractJepEvaluation<T> submitEvaluation(JepFunction<T> evaluationFunction)

Submits an evaluation to the evaluation queue.

Implementation Note:

The result of the evaluation will be returned through AbstractJepEvaluation which is a CompletableFuture.

Type Parameters:

T - Type of the result of the evaluation.

Parameters:

evaluationFunction - JepFunction with evaluation to be done by the Jep instance.

Returns:

An AbstractJepEvaluation evaluation object that can be used to retrieve the result of the evaluation.
