/**
 * This class represents the successful result of the PKIX certification 
 * path builder algorithm. All certification paths that are built and
 * returned using this algorithm are also validated according to the PKIX
 * certification path validation algorithm.<br />
 * <br />
 * Instances of <code>PKIXCertPathBuilderResult</code> are returned by 
 * the <code>build</code> method of <code>CertPathBuilder</code>
 * objects implementing the PKIX algorithm.<br />
 * <br />
 * All <code>PKIXCertPathBuilderResult</code> objects contain the 
 * certification path constructed by the build algorithm, the
 * valid policy tree and subject public key resulting from the build 
 * algorithm, and a <code>TrustAnchor</code> describing the certification 
 * authority (CA) that served as a trust anchor for the certification path.<br />
 * <br />
 * <b>Concurrent Access</b><br />
 * <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.
