/** | |
* 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> | |
