Package org.alfresco.repo.content.transform

Class LocalFailoverTransform

java.lang.Object

org.alfresco.repo.content.transform.AbstractLocalTransform

org.alfresco.repo.content.transform.LocalFailoverTransform

All Implemented Interfaces:

LocalTransform

public class LocalFailoverTransform
extends AbstractLocalTransform

Transformer that passes a document to a sequence of transforms until one succeeds. Instances are automatically created for transformers identified by alfresco/transform json files and returned from T-Engines which are themselves identified by global properties the match the pattern localTransform.<name>.url. The transforms take place in a separate process (typically a Docker container).
