Class JavetLibLoader

java.lang.Object

com.caoccao.javet.interop.loader.JavetLibLoader

public final class JavetLibLoader
extends java.lang.Object

The type Javet lib loader is the one that actually loads the JNI library based on JS runtime type. It is managed by a dedicated classloader (not the default classloader) so that unload is possible. It is not supposed to be called directly by the applications via the default classloader.

It accepts a listener which can specify: (1) To deploy the JNI library to a custom location to work around the permission issues. (2) To skip the JNI library deployment to improve the performance and reduce the jar file size.
