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 PKIXCertPathBuilderResult are returned by the build method of CertPathBuilder objects implementing the PKIX algorithm. 
All 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 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.

Creates an instance of PKIXCertPathBuilderResult containing the specified parameters. 
Params:
  • certPath – the validated CertPath
  • trustAnchor – a TrustAnchor describing the CA that served as a trust anchor for the certification path
  • policyTree – the immutable valid policy tree, or null if there are no valid policies
  • subjectPublicKey – the public key of the subject
Throws:
