/**
 * 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.
 *
 * Instances of {@code PKIXCertPathBuilderResult} are returned by
 * the {@code build} method of {@code CertPathBuilder}
 * objects implementing the PKIX algorithm.
 *
 * 
All {@code PKIXCertPathBuilderResult} 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} describing the certification
 * authority (CA) that served as a trust anchor for the certification path.
 * 

 * Concurrent Access
 * 
 * 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.
