getPrefixForURI

public String getPrefixForURI(String uri)

Get a prefix for a namespace URI. This method will ALWAYS return a valid prefix - if the given URI is already mapped in this serialization, we return the previous prefix. If it is not mapped, we will add a new mapping and return a generated prefix of the form "ns".

Parameters:

Returns:

prefix

getPrefixForURI

public String getPrefixForURI(String uri,
                              String defaultPrefix)

Get a prefix for the given namespace URI. If one has already been defined in this serialization, use that. Otherwise, map the passed default prefix to the URI, and return that. If a null default prefix is passed, use one of the form "ns"

getPrefixForURI

public String getPrefixForURI(String uri,
                              String defaultPrefix,
                              boolean attribute)

Get a prefix for the given namespace URI. If one has already been defined in this serialization, use that. Otherwise, map the passed default prefix to the URI, and return that. If a null default prefix is passed, use one of the form "ns"

Register prefix for the indicated uri

Parameters:

prefix -

uri - is the namespace uri

getCurrentMessage

public Message getCurrentMessage()

Return the current message

getMessageContext

public MessageContext getMessageContext()

Get the MessageContext we're operating with

qName2String

                           boolean writeNS)

Convert QName to a string of the form :

Parameters:

qName -

Returns:

prefixed qname representation for serialization.

qName2String

public String qName2String(javax.xml.namespace.QName qName)

attributeQName2String

public String attributeQName2String(javax.xml.namespace.QName qName)

Convert attribute QName to a string of the form : There are slightly different rules for attributes: - There is no default namespace - any attribute in a namespace must have a prefix

Parameters:

qName - QName

Returns:

prefixed qname representation for serialization.

getQNameForClass

public javax.xml.namespace.QName getQNameForClass(Class cls)

Get the QName associated with the specified class.

Parameters:

cls - Class of an object requiring serialization.

Returns:

appropriate QName associated with the class.

isPrimitive

public boolean isPrimitive(Object value)

Indicates whether the object should be interpretted as a primitive for the purposes of multi-ref processing. A primitive value is serialized directly instead of using id/href pairs. Thus primitive serialization/deserialization is slightly faster.

Parameters:

value - to be serialized

Returns:

true/false

serialize

public void serialize(javax.xml.namespace.QName elemQName,
                      Attributes attributes,
                      Object value)
               throws IOException

Serialize the indicated value as an element with the name indicated by elemQName. The attributes are additional attribute to be serialized on the element. The value is the object being serialized. (It may be serialized directly or serialized as an mult-ref'd item) The value is an Object, which may be a wrapped primitive, the javaType is the actual unwrapped object type. The xmlType (if specified) is the QName of the type that is used to set xsi:type. If not specified, xsi:type is set by using the javaType to find an appopriate xmlType from the TypeMappingRegistry. The sendNull flag indicates whether null values should be sent over the wire (default is to send such values with xsi:nil="true"). The sendType flag indicates whether the xsi:type flag should be sent (default is true).

Parameters:

elemQName - is the QName of the element

attributes - are additional attributes

value - is the object to serialize

Throws:

IOException

serialize

                      javax.xml.namespace.QName xmlType,
                      boolean sendNull,
                      Boolean sendType)

Serialize the indicated value as an element with the name indicated by elemQName. The attributes are additional attribute to be serialized on the element. The value is the object being serialized. (It may be serialized directly or serialized as an mult-ref'd item) The value is an Object, which may be a wrapped primitive. The xmlType (if specified) is the QName of the type that is used to set xsi:type. The sendNull flag indicates whether null values should be sent over the wire (default is to send such values with xsi:nil="true"). The sendType flag indicates whether the xsi:type flag should be sent (default is true).

Parameters:

elemQName - is the QName of the element

attributes - are additional attributes
