| 42 | * The document handler that receives parse events that an XML parser sends while it |
| 43 | * is parsing an XML document representing a <code>WebRowSet</code> object. The |
| 44 | * parser sends strings to this <code>XmlReaderContentHandler</code> and then uses |
| 45 | * these strings as arguments for the <code>XmlReaderContentHandler</code> methods |
| 46 | * it invokes. The final goal of the SAX parser working with an |
| 47 | * <code>XmlReaderContentHandler</code> object is to read an XML document that represents |
| 48 | * a <code>RowSet</code> object. |
| 49 | * <P> |
| 50 | * A rowset consists of its properties, metadata, and data values. An XML document |
| 51 | * representating a rowset includes the values in these three categories along with |
| 52 | * appropriate XML tags to identify them. It also includes a top-level XML tag for |
| 53 | * the rowset and three section tags identifying the three categories of values. |
| 54 | * <P> |
| 55 | * The tags in an XML document are hierarchical. |
| 56 | * This means that the top-level tag, <code>RowSet</code>, is |
| 57 | * followed by the three sections with appropriate tags, which are in turn each |
| 58 | * followed by their constituent elements. For example, the <code>properties</code> |
| 59 | * element will be followed by an element for each of the properties listed in |
| 60 | * in this <code>XmlReaderContentHandler</code> object's <code>properties</code> |
| 61 | * field. The content of the other two fields, <code>colDef</code>, which lists |
| 62 | * the rowset's metadata elements, and <code>data</code>, which lists the rowset's data |
| 63 | * elements, are handled similarly . |
| 64 | * <P> |
| 65 | * This implementation of <code>XmlReaderContentHandler</code> provides the means for the |
| 66 | * parser to determine which elements need to have a value set and then to set |
| 67 | * those values. The methods in this class are all called by the parser; an |
| 68 | * application programmer never calls them directly. |
