aoqi@0 | 46 | * |
aoqi@0 | 47 | * <p>This class provides a default implementation of the SAX2 |
aoqi@0 | 48 | * {@link org.xml.sax.Attributes Attributes} interface, with the |
aoqi@0 | 49 | * addition of manipulators so that the list can be modified or |
aoqi@0 | 50 | * reused.</p> |
aoqi@0 | 51 | * |
aoqi@0 | 52 | * <p>There are two typical uses of this class:</p> |
aoqi@0 | 53 | * |
aoqi@0 | 54 | * <ol> |
aoqi@0 | 55 | * <li>to take a persistent snapshot of an Attributes object |
aoqi@0 | 56 | * in a {@link org.xml.sax.ContentHandler#startElement startElement} event; or</li> |
aoqi@0 | 57 | * <li>to construct or modify an Attributes object in a SAX2 driver or filter.</li> |
aoqi@0 | 58 | * </ol> |
aoqi@0 | 59 | * |
aoqi@0 | 60 | * <p>This class replaces the now-deprecated SAX1 {@link |
aoqi@0 | 61 | * org.xml.sax.helpers.AttributeListImpl AttributeListImpl} |
aoqi@0 | 62 | * class; in addition to supporting the updated Attributes |
aoqi@0 | 63 | * interface rather than the deprecated {@link org.xml.sax.AttributeList |
aoqi@0 | 64 | * AttributeList} interface, it also includes a much more efficient |
aoqi@0 | 65 | * implementation using a single array rather than a set of Vectors.</p> |
