use of org.apache.axis.description.ElementDesc in project Lucee by lucee.

the class BeanDeserializer method onStartChild.

/**
 * Deserializer interface called on each child element encountered in
 * the XML stream.
 * @param namespace is the namespace of the child element
 * @param localName is the local name of the child element
 * @param prefix is the prefix used on the name of the child element
 * @param attributes are the attributes of the child element
 * @param context is the deserialization context.
 * @return is a Deserializer to use to deserialize a child (must be
 * a derived class of SOAPHandler) or null if no deserialization should
 * be performed.
