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.

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
.
Returns the depth of this node in the valid policy tree.
Returns the set of expected policies that would satisfy this node's valid policy in the next certificate to be processed.
Set
of expected policy
String
OIDs, or an immutable Set
with
the single special value "any-policy". For the root node, this method
always returns a Set
with the single value "any-policy".
Returns the parent of this node, or null
if this is the
root node.
null
if this is the
root node
Returns the set of policy qualifiers associated with the valid policy represented by this node.
Set
of
PolicyQualifierInfo
s. For the root node, this
is always an empty Set
.
Returns the valid policy represented by this node.
String
OID of the valid policy
represented by this node, or the special value "any-policy". For
the root node, this method always returns the special value "any-policy".
Returns the criticality indicator of the certificate policy extension in the most recently processed certificate.
true
if extension marked critical,
false
otherwise. For the root node, false
is always returned.
