Class StreamingValidatorImpl
java.lang.Object
com.sun.tools.rngdatatype.helpers.StreamingValidatorImpl
- All Implemented Interfaces:
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); } .... }

- Specified by:
addCharacters
in interfaceDatatypeStreamingValidator
-
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 interfaceDatatypeStreamingValidator
- Returns:
- True if it is valid. False if otherwise.
-
checkValid
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 interfaceDatatypeStreamingValidator
- Throws:
DatatypeException
- If the callee supports the diagnosis and the accumulated literal is invalid, then this exception that possibly contains diagnosis information is thrown.
