org.alfresco.repo.rendition2.RenditionDefinition2Impl

org.alfresco.repo.rendition2.TransformDefinition

All Implemented Interfaces:

RenditionDefinition2

public class TransformDefinition
extends RenditionDefinition2Impl

A TransformDefinition is a transient RenditionDefinition2 that provides a target mimetype and transform options just like a RenditionDefinition2. However one should be created for each transform request, so that additional client supplied data can be included and returned in the response to the client. It also identifies the reply queue to be used.

When it is known that the same target mimetype and transform options are being supplied many times a transform name should be supplied so that the transform registry is able to use the name as a key into a cache used to work out if the transform is possible. The transform name is prefixed TRANSFORM_NAMESPACE to avoid clashes with rendition names.
