* This class represents the successful result of the PKIX certification

* Instances of <code>PKIXCertPathBuilderResult</code> are returned by
* the <code>build</code> method of <code>CertPathBuilder</code>
* objects implementing the PKIX algorithm.<br />

* All <code>PKIXCertPathBuilderResult</code> objects contain the

* algorithm, and a <code>TrustAnchor</code> describing the certification
* authority (CA) that served as a trust anchor for the certification path.<br />

* <b>Concurrent Access</b><br />

* Unless otherwise specified, the methods defined in this class are not
* thread-safe. Multiple threads that need to access a single
* object concurrently should synchronize amongst themselves and
* provide the necessary locking. Multiple threads each manipulating
* separate objects need not synchronize.
