Method Detail

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

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<num>".
