Class JEPThreadPool

java.lang.Object

org.grobid.core.jni.JEPThreadPool

public class JEPThreadPool
extends java.lang.Object

For using DeLFT deep learning models, we use JEP as JNI CPython interpreter. JEP presents the following constraint: A thread that creates a JEP instance must be reused for all method calls to that JEP instance. For ensuring this, we pool the Jep instances in a singleton class.
