All Implemented Interfaces:: org.flowable.content.api.ContentStorage

public class SimpleFileSystemContentStorage
extends java.lang.Object
implements org.flowable.content.api.ContentStorage

(Very) simple implementation of the ContentStorage that relies on the passed metadata to store content. Under a root folder, a division between 'task' and 'process-instance' content is made. New content gets a new UUID assigned and is placed in one of these folders. The id of the returned ContentObject indicates in which folder it is stored.
