org.eclipse.persistence.oxm.mappings.XMLBinaryDataCollectionMapping

Purpose:Provide a mapping for a collection of binary data values that can be treated as either inline binary values or as an attachment.

Responsibilities:

Handle converting binary types (byte[], Image etc) to base64
Make callbacks to AttachmentMarshaller/AttachmentUnmarshaller
Write out approriate attachment information (xop:include)

XMLBinaryDataCollectionMapping represents a mapping of a collection of binary data in the object model to XML. This can either be written directly as inline binary data (base64) or passed through as an MTOM or SWAREF attachment.

The following types are allowable to be mapped using an XMLBinaryDataMapping:

java.awt.Image
byte[]
javax.activation.DataHandler
javax.xml.transform.Source
javax.mail.internet.MimeMultipart

Setting the XPath: TopLink XML mappings make use of XPath statements to find the relevant data in an XML document. The XPath statement is relative to the context node specified in the descriptor. The XPath may contain path and positional information; the last node in the XPath forms the local node for the binary mapping. The XPath is specified on the mapping using the setXPath method.

Inline Binary Data: Set this flag if you want to always inline binary data for this mapping. This will disable consideration for attachment handling for this mapping.

SwaRef: Set this flag in order to specify that the target node of this mapping is of type xs:swaref @see org.eclipse.persistence.oxm.attachment.XMLAttachmentMarshaller @see org.eclipse.persistence.oxm.attachment.XMLAttachmentUnmarshaller @see org.eclipse.persistence.oxm.mappings.MimeTypePolicy @since TopLink 11.1.1.0.0g

        if (!getType().getInstanceClassName().equals("javax.activation.DataHandler")) {
            mapping.setAttributeElementClass(getType().getInstanceClass());
        }
        mapping.setMimeTypePolicy(mimeTypePolicy);
        mapping.setXPath(xpath);


        ((XMLField)mapping.getField()).setSchemaType(XMLConstants.BASE_64_BINARY_QNAME);


        if (shouldAddInstanceClassConverter()) {
            InstanceClassConverter converter = new InstanceClassConverter();
            converter.setCustomClass(getType().getInstanceClass());
            mapping.setValueConverter(converter);
