Class TextContentChecker

java.lang.Object
  org.whattf.checker.Checker
      org.whattf.checker.TextContentChecker

All Implemented Interfaces:

ContentHandler

public final class TextContentChecker
extends Checker

Checks the textContent of elements whose textContent need special non-schema treatment. To smooth code reuse between a conformance checker and editors that only allow RELAX NG plus custom datatypes, this class uses objects that implement DatatypeStreamingValidator.

Examples of elements handled by this class are time, meter and progress.

reset

public void reset()

Description copied from class: Checker
