-/**
- * A validator for X.509 certificates when approving certificate chains.
- *
- * <p>Concrete subclasses can be passed to the {@link
- * PKIXParameters#setCertPathCheckers(java.util.List)} and {@link
- * PKIXParameters#addCertPathChecker(java.security.cert.PKIXCertPathChecker}
- * methods, which are then used to set up PKIX certificate chain
- * builders or validators. These classes then call the {@link
- * #check(java.security.cert.Certificate,java.util.Collection)} method
- * of this class, performing whatever checks on the certificate,
- * throwing an exception if any check fails.
- *
- * <p>Subclasses of this must be able to perform their checks in the
- * backward direction -- from the most-trusted certificate to the target
- * -- and may optionally support forward checking -- from the target to
- * the most-trusted certificate.
- *
- * @see PKIXParameters
