Interface XMLSerializer

All Known Implementing Classes:
MSVValidator, SAXMarshaller

public interface XMLSerializer

Receives XML serialization event

This object coordinates the overall marshalling efforts across different content-tree objects and different target formats.

The following CFG gives the proper sequence of method invocation.

 MARSHALLING  :=  ELEMENT
 ELEMENT      :=  "startElement" NSDECL* "endNamespaceDecls"
                        ATTRIBUTE* "endAttributes" BODY "endElement"
 
 NSDECL       :=  "declareNamespace"
 
 ATTRIBUTE    :=  "startAttribute" ATTVALUES "endAttribute"
 ATTVALUES    :=  "text"*
 
 
 BODY         :=  ( "text" | ELEMENT )*
 

A marshalling of one element consists of two stages. The first stage is for marshalling attributes and collecting namespace declarations. The second stage is for marshalling characters/child elements of that element.

Observe that multiple invocation of "text" is allowed.

Also observe that the namespace declarations are allowed only between "startElement" and "endAttributes".

Method Detail

reportError

public void reportError(ValidationEvent e)
                 throws AbortSerializationException
Errors detected by the XMLSerializable should be either thrown as SAXException or reported through this method. The callee should report an error to the client application and

Throws:
AbortSerializationException

startElement

public void startElement(java.lang.String uri,
                         java.lang.String local)
                  throws org.xml.sax.SAXException
Starts marshalling of an element. Calling this method will push the internal state into the internal stack.

Throws:
org.xml.sax.SAXException

endNamespaceDecls

public void endNamespaceDecls()
                       throws org.xml.sax.SAXException
Switches to the mode to marshal attribute values. This method has to be called after the 1st pass is completed.

Throws:
org.xml.sax.SAXException

endAttributes

public void endAttributes()
                   throws org.xml.sax.SAXException
Switches to the mode to marshal child texts/elements. This method has to be called after the 2nd pass is completed.

Throws:
org.xml.sax.SAXException

endElement

public void endElement()
                throws org.xml.sax.SAXException
Ends marshalling of an element. Pops the internal stack.

Throws:
org.xml.sax.SAXException

text

public void text(java.lang.String text,
                 java.lang.String fieldName)
          throws org.xml.sax.SAXException
Marshalls text.

This method can be called (i) after the startAttribute method and (ii) before the endAttribute method, to marshal attribute values. If the method is called more than once, those texts are considered as separated by whitespaces. For example,

 c.startAttribute();
 c.text("abc");
 c.text("def");
 c.endAttribute("","foo");
 
will generate foo="abc def".

Similarly, this method can be called after the endAttributes method to marshal texts inside elements. The same rule about multiple invokations apply to this case, too. For example,

 c.startElement("","foo");
 c.endNamespaceDecls();
 c.endAttributes();
 c.text("abc");
 c.text("def");
   c.startElement("","bar");
   c.endAttributes();
   c.endElement();
 c.text("ghi");
 c.endElement();
 
will generate <foo>abc def<bar/>ghi</foo>.

Throws:
org.xml.sax.SAXException

startAttribute

public void startAttribute(java.lang.String uri,
                           java.lang.String local)
                    throws org.xml.sax.SAXException
Starts marshalling of an attribute. The marshalling of an attribute will be done by
  1. call the startAttribute method
  2. call the text method (several times if necessary)
  3. call the endAttribute method
No two attributes can be marshalled at the same time. Note that the whole attribute marshalling must be happened after the startElement method and before the endAttributes method.

Throws:
org.xml.sax.SAXException

endAttribute

public void endAttribute()
                  throws org.xml.sax.SAXException
Throws:
org.xml.sax.SAXException

getNamespaceContext

public NamespaceContext2 getNamespaceContext()
Obtains a namespace context object, which is used to declare/obtain namespace bindings.


onID

public java.lang.String onID(IdentifiableObject owner,
                             java.lang.String value)
                      throws org.xml.sax.SAXException
Notifies the serializer that an ID value has just marshalled. The serializer may or may not check the consistency of ID/IDREFs and may throw a SAXException.

Parameters:
owner - JAXB content object that posesses the ID.
value - The value of the ID.
Returns:
Return the value parameter without any modification, so that the invocation of this method can be done transparently by a transducer.
Throws:
org.xml.sax.SAXException

onIDREF

                         throws org.xml.sax.SAXException
Notifies the serializer that an IDREF value has just marshalled. The serializer may or may not check the consistency of ID/IDREFs and may throw a SAXException.

Returns:
Return the value parameter without any modification. so that the invocation of this method can be done transparently by a transducer.
Throws:
org.xml.sax.SAXException

                 throws org.xml.sax.SAXException
This method is called when an JAXBObject object is found while the marshaller is in the "element" mode (i.e. marshalling a content model of an element)

Parameters:
