Class SAXMarshaller

java.lang.Object
  net.sf.jour.config.impl.runtime.SAXMarshaller

All Implemented Interfaces:

XMLSerializer

public class SAXMarshaller

extends java.lang.Object

implements XMLSerializer

XMLSerializer that produces SAX2 events. To marshal an object, create an instance of SAXMarshaller and call the serializeElements method of the XMLSerializable object that you want to marshal.

Constructor Summary

SAXMarshaller(org.xml.sax.ContentHandler _writer, com.sun.xml.bind.marshaller.NamespacePrefixMapper prefixMapper, MarshallerImpl _owner)
Creates a marshalling context by designating the ContentHandler that receives generated SAX2 events.

Method Summary

void	childAsAttributes(com.sun.xml.bind.JAXBObject o, java.lang.String fieldName) This method is called when an JAXBObject object is found while the marshaller is in the "attribute" mode (i.e. marshalling attributes of an element)
void	childAsBody(com.sun.xml.bind.JAXBObject o, java.lang.String fieldName) 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)
void	childAsURIs(com.sun.xml.bind.JAXBObject o, java.lang.String fieldName) This method is called when an JAXBObject object is found while the marshaller is in the "URI" mode.
void	endAttribute()
void	endAttributes() Switches to the "marshal child texts/elements" mode.
void	endElement() Ends marshalling of an element.
void	endNamespaceDecls() Switches to the mode to marshal attribute values.
NamespaceContext2	getNamespaceContext() Obtains a namespace context object, which is used to declare/obtain namespace bindings.
java.lang.String	onID(com.sun.xml.bind.marshaller.IdentifiableObject owner, java.lang.String value) Notifies the serializer that an ID value has just marshalled.
java.lang.String	onIDREF(com.sun.xml.bind.marshaller.IdentifiableObject obj) Notifies the serializer that an IDREF value has just marshalled.
(package private) void	reconcileID()
void	reportError(javax.xml.bind.ValidationEvent ve) Errors detected by the XMLSerializable should be either thrown as SAXException or reported through this method.
void	reportMissingObjectError(java.lang.String fieldName)
void	startAttribute(java.lang.String uri, java.lang.String local) Starts marshalling of an attribute.
void	startElement(java.lang.String uri, java.lang.String local) Starts marshalling of an element.
void	text(java.lang.String text, java.lang.String fieldName) Marshalls text.

Constructor Detail

SAXMarshaller

public SAXMarshaller(org.xml.sax.ContentHandler _writer,
                     com.sun.xml.bind.marshaller.NamespacePrefixMapper prefixMapper,
                     MarshallerImpl _owner)

Creates a marshalling context by designating the ContentHandler that receives generated SAX2 events.

Method Detail

getNamespaceContext

public NamespaceContext2 getNamespaceContext()

Description copied from interface: XMLSerializer

Obtains a namespace context object, which is used to declare/obtain namespace bindings.

Specified by:

getNamespaceContext in interface XMLSerializer

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.

Specified by:

startElement in interface XMLSerializer

Throws:

org.xml.sax.SAXException

endNamespaceDecls

public void endNamespaceDecls()
                       throws org.xml.sax.SAXException

Description copied from interface: XMLSerializer

Switches to the mode to marshal attribute values. This method has to be called after the 1st pass is completed.

Specified by:

endNamespaceDecls in interface XMLSerializer

Throws:

org.xml.sax.SAXException

endAttributes

public void endAttributes()
                   throws org.xml.sax.SAXException

Switches to the "marshal child texts/elements" mode. This method has to be called after the 1st pass is completed.

Specified by:

endAttributes in interface XMLSerializer

Throws:

org.xml.sax.SAXException

endElement

public void endElement()
                throws org.xml.sax.SAXException

Ends marshalling of an element. Pops the internal stack.

Specified by:

endElement in interface XMLSerializer

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.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>.

Specified by:

text in interface XMLSerializer

Throws:

org.xml.sax.SAXException

startAttribute

public void startAttribute(java.lang.String uri,
                           java.lang.String local)

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.

Specified by:

startAttribute in interface XMLSerializer

endAttribute

public void endAttribute()

Specified by:

endAttribute in interface XMLSerializer

onID

public java.lang.String onID(com.sun.xml.bind.marshaller.IdentifiableObject owner,

                      throws org.xml.sax.SAXException

Description copied from interface: XMLSerializer

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.

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.

Return the value parameter without any modification. so that the invocation of this method can be done transparently by a transducer.
