| * |
| * <p>This class encapsulates the logic of Namespace processing: it |
| * tracks the declarations currently in force for each context and |
| * automatically processes qualified XML names into their Namespace |
| * parts; it can also be used in reverse for generating XML qnames |
| * from Namespaces.</p> |
| * |
| * <p>Namespace support objects are reusable, but the reset method |
| * must be invoked between each session.</p> |
| * |
| * <p>Here is a simple session:</p> |
| * |
| * <pre> |
| * String parts[] = new String[3]; |
| * NamespaceSupport support = new NamespaceSupport(); |
| * |
| * support.pushContext(); |
| * support.declarePrefix("", "http://www.w3.org/1999/xhtml"); |
| * support.declarePrefix("dc", "http://www.purl.org/dc#"); |
| * |
| * parts = support.processName("p", parts, false); |
| * System.out.println("Namespace URI: " + parts[0]); |
| * System.out.println("Local name: " + parts[1]); |
| * System.out.println("Raw name: " + parts[2]); |
| * |
| * parts = support.processName("dc:title", parts, false); |
| * System.out.println("Namespace URI: " + parts[0]); |
| * System.out.println("Local name: " + parts[1]); |
| * System.out.println("Raw name: " + parts[2]); |
| * |
| * support.popContext(); |
| * </pre> |
| * |
| * <p>Note that this class is optimized for the use case where most |
| * elements do not contain Namespace declarations: if the same |
| * prefix/URI mapping is repeated for each context (for example), this |
| * class will be somewhat less efficient.</p> |
| * |
| * <p>Although SAX drivers (parsers) may choose to use this class to |
| * implement namespace handling, they are not required to do so. |
| * Applications must track namespace information themselves if they |
| * want to use namespace information. |
