Method Detail

onStartElement

public void onStartElement(String namespace,
                           String localName,
                           String prefix,

                           DeserializationContext context)
                    throws SAXException

Set the bean properties that correspond to element attributes.

This method is invoked after startElement when the element requires deserialization (i.e. the element is not an href and the value is not nil.)

Specified by:

onStartElement in interface Deserializer

Overrides:

onStartElement in class DeserializerImpl

Parameters:

namespace - is the namespace of the element

localName - is the name of the element

prefix - is the prefix of the element

attributes - are the attributes on the element...used to get the type

context - is the DeserializationContext

Throws:

SAXException

---

onStartChild

public SOAPHandler onStartChild(String namespace,
                                String localName,
                                String prefix,
                                Attributes attributes,
                                DeserializationContext context)
                         throws SAXException

Deserializer interface called on each child element encountered in the XML stream.

Specified by:

onStartChild in interface Deserializer

Overrides:

onStartChild in class DeserializerImpl

Parameters:

namespace - is the namespace of the child element

localName - is the local name of the child element

prefix - is the prefix used on the name of the child element

attributes - are the attributes of the child element

context - is the deserialization context.

Returns:

is a Deserializer to use to deserialize a child (must be a derived class of SOAPHandler) or null if no deserialization should be performed.

Throws:

SAXException

---

onEndElement

public void onEndElement(String namespace,
                         String localName,
                         DeserializationContext context)
                  throws SAXException

Check that we have a valid bean instance

Specified by:

onEndElement in interface Deserializer

Overrides:

onEndElement in class DeserializerImpl

Parameters:

namespace - is the namespace of the child element

localName - is the local name of the child element

context - is the deserialization context

Throws:

SAXException

---

getAnyPropertyDesc

public BeanPropertyDescriptor getAnyPropertyDesc()

Get a BeanPropertyDescriptor which indicates where we should put extensibility elements (i.e. XML which falls under the auspices of an <xsd:any> declaration in the schema)

Returns:

an appropriate BeanPropertyDescriptor, or null

---

getDeserializer

protected Deserializer getDeserializer(javax.xml.namespace.QName xmlType,
                                       Class javaType,
                                       String href,
                                       DeserializationContext context)

Get the Deserializer for the attribute or child element.

Parameters:

xmlType - QName of the attribute/child element or null if not known.

javaType - Class of the corresponding property

href - String is the value of the href attribute, which is used to determine whether the child element is complete or an href to another element.

context - DeserializationContext

Returns:

Deserializer or null if not found.

characters

public void characters(char[] p1,
                       int p2,
                       int p3)
                throws SAXException

This will assign text content to the bean property that is an element with the asContent flag set to true. There can only be one, or is there a way to know which? TDI 22-June-2004

Specified by:

characters in interface ContentHandler

Throws:

SAXException
