Examples with ContainerClassLoaderFilterFactory org.mule.runtime.container.internal.ContainerClassLoaderFilterFactory used on opensource projects

Example 1 with ContainerClassLoaderFilterFactory

use of org.mule.runtime.container.internal.ContainerClassLoaderFilterFactory in project mule by mulesoft.

the class IsolatedClassLoaderFactory method createContainerArtifactClassLoader.

/**
 * Creates an {@link ArtifactClassLoader} for the container. The difference between a mule container {@link ArtifactClassLoader}
 * in standalone mode and this one is that it has to be aware that the parent class loader has all the URLs loaded in launcher
 * app class loader so it has to create a particular look policy to resolve classes as CHILD_FIRST.
 * <p/>
 * In order to do that a {@link FilteringArtifactClassLoader} resolve is created with and empty look policy (meaning that
 * CHILD_FIRST strategy will be used) for the {@link URL}s that are going to be exposed from the container class loader. This
 * would be the parent class loader for the container so instead of going directly the launcher application class loader that
 * has access to the whole classpath this filtering class loader will resolve only the classes for the {@link URL}s defined to
 * be in the container.
 *
 * @param testContainerClassLoaderFactory {@link TestContainerClassLoaderFactory} that has the logic to create a container class
 *        loader
 * @param artifactsUrlClassification the classifications to get plugins {@link URL}s
 * @return an {@link ArtifactClassLoader} for the container
