| 34 /** | |
| 35 * Represents an XML tag name (and attributes for start tags.) | |
| 36 * | |
| 37 * <p> | |
| 38 * This object is used so reduce the number of method call parameters | |
| 39 * among unmarshallers. | |
| 40 * | |
| 41 * An instance of this is expected to be reused by the caller of | |
| 42 * {@link XmlVisitor}. Note that the rest of the unmarshaller may | |
| 43 * modify any of the fields while processing an event (such as to | |
| 44 * intern strings, replace attributes), | |
| 45 * so {@link XmlVisitor} should reset all fields for each use. | |
| 46 * | |
| 47 * <p> | |
| 48 * The 'qname' parameter, which holds the qualified name of the tag | |
| 49 * (such as 'foo:bar' or 'zot'), is not used in the typical unmarshalling | |
| 50 * route and it's also expensive to compute for some input. | |
| 51 * Thus this parameter is computed lazily. | |
