Class PKIXCertPathChecker

protected PKIXCertPathChecker()

Default constructor.

public abstract void check(Certificate cert,
                           Collection unresolvedCritExts)
            throws CertPathValidatorException

Checks a certificate, removing any critical extensions that are resolved in this check.

Parameters:

cert - The certificate to check.

unresolvedCritExts - The (mutable) collection of as-of-yet unresolved critical extensions, as OID strings.

Throws:

CertPathValidatorException - If this certificate fails this check.

public Object clone()

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object).

If the Object you call clone() on does not implement Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }
 

Overrides:

clone in interface Object

Returns:

a copy of the Object

public abstract Set getSupportedExtensions()

Returns an immutable set of X.509 extension object identifiers (OIDs) supported by this PKIXCertPathChecker.

Returns:

An immutable set of Strings of the supported X.509 OIDs, or null if no extensions are supported.

public abstract void init(boolean forward)
            throws CertPathValidatorException

Initialize this PKIXCertPathChecker. If subclasses support forward checking, a value of true can be passed to this method, and certificates can be validated from the target certificate to the most-trusted certifcate.

Parameters:

forward - The direction of this PKIXCertPathChecker.

Throws:

CertPathValidatorException - If forward is true and this class does not support forward checking.

public abstract boolean isForwardCheckingSupported()

Returns whether or not this class supports forward checking.

Returns:

Whether or not this class supports forward checking.
