PolicyNode
interface 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 PKIXParameters. However, the valid policy tree is available for more sophisticated applications, especially those that process policy qualifiers.
PKIXCertPathValidatorResult.getPolicyTree returns the root node of the valid policy tree. The tree can be traversed using the getChildren and getParent methods. Data about a particular node can be retrieved using other methods of PolicyNode.
Concurrent Access
All PolicyNode objects must be immutable and thread-safe. Multiple threads may concurrently invoke the methods defined in this class on a single 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.
Summary
| Public methods | |
|---|---|
| abstract MutableIterator<PolicyNode!>! |
Returns an iterator over the children of this node. |
| abstract Int |
getDepth()Returns the depth of this node in the valid policy tree. |
| abstract MutableSet<String!>! |
Returns the set of expected policies that would satisfy this node's valid policy in the next certificate to be processed. |
| abstract PolicyNode! |
Returns the parent of this node, or |
| abstract MutableSet<out PolicyQualifierInfo!>! |
Returns the set of policy qualifiers associated with the valid policy represented by this node. |

Returns the valid policy represented by this node. |
| abstract Boolean |
Returns the criticality indicator of the certificate policy extension in the most recently processed certificate. |
Public methods
getChildren
abstract fun getChildren(): MutableIterator<PolicyNode!>!
Returns an iterator over the children of this node. Any attempts to modify the children of this node through the Iterator's remove method must throw an UnsupportedOperationException.
| Return | |
|---|---|
MutableIterator<PolicyNode!>! |
an iterator over the children of this node |
getDepth
abstract fun getDepth(): Int
Returns the depth of this node in the valid policy tree.
| Return | |
|---|---|
Int |
the depth of this node (0 for the root node, 1 for its children, and so on) |
getExpectedPolicies
abstract fun getExpectedPolicies(): MutableSet<String!>!
Returns the set of expected policies that would satisfy this node's valid policy in the next certificate to be processed.
| Return | |
|---|---|
MutableSet<String!>! |
an immutable Set of expected policy String OIDs. For the root node, this method always returns a Set with one element, the special anyPolicy OID: "2.5.29.32.0". |
getParent
abstract fun getParent(): PolicyNode!
Returns the parent of this node, or null if this is the root node.
| Return | |
|---|---|
PolicyNode! |
the parent of this node, or null if this is the root node |
getPolicyQualifiers
abstract fun getPolicyQualifiers(): MutableSet<out PolicyQualifierInfo!>!
Returns the set of policy qualifiers associated with the valid policy represented by this node.
| Return | |
|---|---|
MutableSet<out PolicyQualifierInfo!>! |
an immutable Set of PolicyQualifierInfos. For the root node, this is always an empty Set. |
getValidPolicy
abstract fun getValidPolicy(): String!
Returns the valid policy represented by this node.
| Return | |
|---|---|
String! |
the String OID of the valid policy represented by this node. For the root node, this method always returns the special anyPolicy OID: "2.5.29.32.0". |
isCritical
abstract fun isCritical(): Boolean
Returns the criticality indicator of the certificate policy extension in the most recently processed certificate.
| Return | |
|---|---|
Boolean |
true if extension marked critical, false otherwise. For the root node, false is always returned. |
