| /** |
| * Dummy implementation of {@link DatatypeStreamingValidator}. |
| * |
| * <p> |
| * This implementation can be used as a quick hack when the performance |
| * of streaming validation is not important. And this implementation |
| * also shows you how to implement the DatatypeStreamingValidator interface. |
| * |
| * <p> |
| * Typical usage would be: |
| * <PRE><XMP> |
| * class MyDatatype implements Datatype { |
| * .... |
| * public DatatypeStreamingValidator createStreamingValidator( ValidationContext context ) { |
| * return new StreamingValidatorImpl(this,context); |
| * } |
| * .... |
| * } |
| * </XMP></PRE> |
