Examples of java.security.cert.PolicyNode

java.security.cert.PolicyNode
An immutable valid policy tree node as defined by the PKIX certification path validation algorithm.
One of the outputs of the PKIX certification path validation algorithm is a valid policy tree, which includes the policies that were determined to be valid, how this determination was reached, and any policy qualifiers encountered. This tree is of depth n, where n is the length of the certification path that has been validated.
Most applications will not need to examine the valid policy tree. They can achieve their policy processing goals by setting the policy-related parameters in {@code PKIXParameters}. However, the valid policy tree is available for more sophisticated applications, especially those that process policy qualifiers.
{@link PKIXCertPathValidatorResult#getPolicyTree() PKIXCertPathValidatorResult.getPolicyTree} returns the root node of thevalid policy tree. The tree can be traversed using the {@link #getChildren getChildren} and {@link #getParent getParent} methods.Data about a particular node can be retrieved using other methods of {@code PolicyNode}.
Concurrent Access
All {@code PolicyNode} objects must be immutable andthread-safe. Multiple threads may concurrently invoke the methods defined in this class on a single {@code PolicyNode} object (or more than one)with no ill effects. This stipulation applies to all public fields and methods of this class and any added or overridden by subclasses. @since 1.4 @author Sean Mullan
