public abstract class AttachmentUnmarshaller
extends java.lang.Object
Enables JAXB unmarshalling of a root document containing optimized binary data formats.
This API enables an efficient cooperative processing of optimized binary data formats between a JAXB 2.0 implementation and MIME-based package processor (MTOM/XOP and WS-I AP 1.0). JAXB unmarshals the body of a package, delegating the understanding of the packaging format being used to a MIME-based package processor that implements this abstract class.
This abstract class identifies if a package requires XOP processing, isXOPPackage() and provides retrieval of binary content stored as attachments by content-id.

public abstract javax.activation.DataHandler getAttachmentAsDataHandler(java.lang.String cid)
Lookup MIME content by content-id, cid, and return as a DataHandler.
The returned DataHandler instance must be configured
to meet the following required mapping constaint.

Read-only property that returns true if JAXB unmarshaller needs to perform XOP processing.
This method returns true when the constraints specified
in Identifying XOP Documents are met.
This value must not change during the unmarshalling process.
