AttachmentUnmarshaller


javax.xml.bind.attachment
Class AttachmentUnmarshaller

java.lang.Object
  javax.xml.bind.attachment.AttachmentUnmarshaller
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.

Identifying the content-id, cid, to pass to getAttachment*(String cid)

AttachmentUnmarshaller

public AttachmentUnmarshaller()
Method Detail

getAttachmentAsDataHandler

public abstract 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.

Required Mappings between MIME and Java Types
MIME Type Java Type
DataHandler.getContentType() instanceof DataHandler.getContent()
image/gif java.awt.Image
image/jpeg java.awt.Image
text/xml or application/xml javax.xml.transform.Source
Note that it is allowable to support additional mappings.

Parameters:
cid - It is expected to be a valid lexical form of the XML Schema xs:anyURI datatype. If isXOPPackage() ==true, it must be a valid URI per the cid: URI scheme (see RFC 2387)
Returns:
a DataHandler that represents the MIME attachment.
Throws:
java.lang.IllegalArgumentException - if the attachment for the given cid is not found.

getAttachmentAsByteArray

public abstract byte[] getAttachmentAsByteArray(java.lang.String cid)

Retrieve the attachment identified by content-id, cid, as a byte[]

.

Parameters:
cid - It is expected to be a valid lexical form of the XML Schema xs:anyURI datatype. If isXOPPackage() ==true, it must be a valid URI per the cid: URI scheme (see RFC 2387)
Returns:
byte[] representation of attachment identified by cid.
Throws:
java.lang.IllegalArgumentException - if the attachment for the given cid is not found.

isXOPPackage

public boolean isXOPPackage()

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.

Returns:
true when MIME context is a XOP Document.
