public class PolicyQualifierInfo extends Object
The ASN.1 definition is as follows:
   PolicyQualifierInfo ::= SEQUENCE {
        policyQualifierId       PolicyQualifierId,
        qualifier               ANY DEFINED BY policyQualifierId }
 
 A certificate policies extension, if present in an X.509 version 3 certificate, contains a sequence of one or more policy information terms, each of which consists of an object identifier (OID) and optional qualifiers. In an end-entity certificate, these policy information terms indicate the policy under which the certificate has been issued and the purposes for which the certificate may be used. In a CA certificate, these policy information terms limit the set of policies for certification paths which include this certificate.
 A Set of PolicyQualifierInfo objects are returned
 by the PolicyNode.getPolicyQualifiers
 method. This allows applications with specific policy requirements to
 process and validate each policy qualifier. Applications that need to
 process policy qualifiers should explicitly set the
 policyQualifiersRejected flag to false (by calling the
 PKIXParameters.setPolicyQualifiersRejected method) before validating
 a certification path.
 
Note that the PKIX certification path validation algorithm specifies
 that any policy qualifier in a certificate policies extension that is
 marked critical must be processed and validated. Otherwise the
 certification path must be rejected. If the
 policyQualifiersRejected flag is set to false, it is up to
 the application to validate all policy qualifiers in this manner in order
 to be PKIX compliant.
 
Concurrent Access
All PolicyQualifierInfo objects must be immutable and
 thread-safe. That is, multiple threads may concurrently invoke the
 methods defined in this class on a single PolicyQualifierInfo
 object (or more than one) with no ill effects. Requiring
 PolicyQualifierInfo objects to be immutable and thread-safe
 allows them to be passed around to various pieces of code without
 worrying about coordinating access.
