Constructor and Description
AbstractXOPType(boolean useXmimeBinaryType, String expectedContentTypes) Create an XOP type.

Method Summary

Modifier and Type	Method and Description
void	addToSchemaElement(org.apache.ws.commons.schema.XmlSchemaElement schemaElement) If the type object merely wants to contribute attributes to the xsd:element element, it can implement this.
protected abstract Attachment	createAttachment(Object object, String id)
protected abstract byte[]	getBytes(Object object) if MtoM is not enabled, we need bytes to turn into base64.
protected abstract String	getContentType(Object object, Context context)
protected abstract Object	readAttachment(Attachment att, Context context)
Object	readMtoM(MessageReader reader, Context context) This is called from base64Type when it recognizes an XOP attachment.
Object	readObject(MessageReader reader, Context context) This defers to the plain base64 type, which calls back into here above for XOP.
boolean	usesXmime()
protected abstract Object	wrapBytes(byte[] bareBytes, String contentType) If one of these types arrives unoptimized, we need to convert it to the desired return type.
void	writeObject(Object object, MessageWriter writer, Context context) Writes the object to the MessageWriter.

Constructor Detail

AbstractXOPType

public AbstractXOPType(boolean useXmimeBinaryType,
                       String expectedContentTypes)

Create an XOP type. This type will use xmime to publish and receive the content type via xmime:base64Binary if useXmimeBinaryType is true. If expectedContentTypes != null, then it will use xmime to advertise expected content types.

Parameters:

useXmimeBinaryType - whether to use xmime:base64Binary.

expectedContentTypes - whether to public xmime:expectedContentTypes.

Method Detail

readMtoM

public Object readMtoM(MessageReader reader,
                       Context context)
                throws DatabindingException

This is called from base64Type when it recognizes an XOP attachment.

Parameters:

reader -

context -

Returns:

Throws:

DatabindingException

readObject

public Object readObject(MessageReader reader,
                         Context context)
                  throws DatabindingException

This defers to the plain base64 type, which calls back into here above for XOP. Read in the XML fragment and create an object.

Specified by:

readObject in class AegisType

Returns:

Throws:

DatabindingException

readAttachment

protected abstract Object readAttachment(Attachment att,
                                         Context context)
                                  throws IOException

Throws:

IOException

writeObject

public void writeObject(Object object,
                        MessageWriter writer,
                        Context context)
                 throws DatabindingException

Description copied from class: AegisType

Writes the object to the MessageWriter.

Specified by:

writeObject in class AegisType

Throws:

DatabindingException

createAttachment

protected abstract Attachment createAttachment(Object object,
                                               String id)

getContentType

protected abstract String getContentType(Object object,
                                         Context context)

wrapBytes

protected abstract Object wrapBytes(byte[] bareBytes,
                                    String contentType)

If one of these types arrives unoptimized, we need to convert it to the desired return type.

Parameters:

bareBytes - the bytes pulled out of the base64.

contentType - when we support xmime:contentType, this will be passed along.

Returns:

getBytes

protected abstract byte[] getBytes(Object object)

if MtoM is not enabled, we need bytes to turn into base64.

Returns:

addToSchemaElement

public void addToSchemaElement(org.apache.ws.commons.schema.XmlSchemaElement schemaElement)

Description copied from class: AegisType

If the type object merely wants to contribute attributes to the xsd:element element, it can implement this.

Overrides:

addToSchemaElement in class AegisType

usesXmime

public boolean usesXmime()

Overrides:

usesXmime in class AegisType
