Package org.alfresco.repo.content.transform

Class LocalPipelineTransformer

java.lang.Object

org.alfresco.repo.content.transform.AbstractLocalTransformer

org.alfresco.repo.content.transform.LocalPipelineTransformer

All Implemented Interfaces:

LocalTransformer

public class LocalPipelineTransformer
extends AbstractLocalTransformer

Transformer that passes a document through a pipeline of transformations to arrive at an target mimetype. 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 localTransformer.<name>.url. The transforms take place in a separate process (typically a Docker container).
