Class StreamingValidatorImpl

    java.lang.Object
      org.relaxng.datatype.helpers.StreamingValidatorImpl

All Implemented Interfaces:
  DatatypeStreamingValidator

    public final class StreamingValidatorImpl

extends java.lang.Object
implements DatatypeStreamingValidator

Dummy implementation of `DatatypeStreamingValidator`.

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.

Typical usage would be:

     class MyDatatype implements Datatype {
         ....
         public DatatypeStreamingValidator createStreamingValidator( ValidationContext context ) {
             return new StreamingValidatorImpl(this,context);
         }
         ....
     }

Constructor Summary
`StreamingValidatorImpl(Datatype baseType, ValidationContext context)`

Method Summary
`void` `addCharacters(char[] buf, int start, int len)` Passes an additional fragment of the literal.
`void` `checkValid()` Similar to the isValid method, but this method throws Exception (with possibly diagnostic information), instead of returning false.
`boolean` `isValid()` Tells if the accumulated literal is valid with respect to the underlying Datatype.

Constructor Detail

### StreamingValidatorImpl

    public StreamingValidatorImpl(Datatype baseType,
                                  ValidationContext context)

Method Detail

### addCharacters

    public void addCharacters(char[] buf,
                              int start,
                              int len)

  Description copied from interface: `DatatypeStreamingValidator`
  Passes an additional fragment of the literal.

  The application can call this method several times, then call the isValid method (or the checkValid method) to check the validity of the accumulated characters.

  Specified by:
    `addCharacters` in interface `DatatypeStreamingValidator`

### isValid

    public boolean isValid()

  Description copied from interface: `DatatypeStreamingValidator`
  Tells if the accumulated literal is valid with respect to the underlying Datatype.

  Specified by:
    `isValid` in interface `DatatypeStreamingValidator`
  Returns:
    True if it is valid. False if otherwise.

### checkValid

    public void checkValid()
                    throws DatatypeException

  Description copied from interface: `DatatypeStreamingValidator`
  Similar to the isValid method, but this method throws Exception (with possibly diagnostic information), instead of returning false.

  Specified by:
    `checkValid` in interface `DatatypeStreamingValidator`
  Throws:
    `DatatypeException` - If the callee supports the diagnosis and the accumulated literal is invalid, then this exception that possibly contains diagnosis information is thrown.
