Examples of org.relaxng.datatype.Datatype

org.relaxng.datatype.Datatype
Datatype object. This object has the following functionality:
1. functionality to identify a class of character sequences. This is done through the isValid method.
2. functionality to produce a "value object" from a character sequence and context information.
3. functionality to test the equality of two value objects.
This interface also defines the createStreamingValidator method, which is intended to efficiently support the validation of large character sequences. @author James Clark @author Kohsuke KAWAGUCHI
