Package com.flowable.content.engine.impl.fs

Class SimpleFileSystemContentStorage

java.lang.Object

com.flowable.content.engine.impl.AbstractContentStorage

com.flowable.content.engine.impl.fs.SimpleFileSystemContentStorage

All Implemented Interfaces:

ContentStorage

public class SimpleFileSystemContentStorage
extends AbstractContentStorage
implements 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.
