Interface PolicyNode
public interface 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.

Method Summary |
Iterator<? extends PolicyNode> |
getChildren()
Returns an iterator over the children of this node. |
int |
getDepth()
Returns the depth of this node in the valid policy tree. |
Set<String> |
getExpectedPolicies()
Returns the set of expected policies that would satisfy this
node's valid policy in the next certificate to be processed. |
PolicyNode |
getParent()
Returns the parent of this node, or null if this is the
root node. |
Set<? extends PolicyQualifierInfo> |
getPolicyQualifiers()
Returns the set of policy qualifiers associated with the
valid policy represented by this node. |
String |
getValidPolicy()
Returns the valid policy represented by this node. |
boolean |
isCritical()
Returns the criticality indicator of the certificate policy extension
in the most recently processed certificate. |
getParent
PolicyNode getParent()
- Returns the parent of this node, or
null if this is the
root node.
- Returns:
- the parent of this node, or
null if this is the
root node
getChildren
Iterator<? extends PolicyNode> getChildren()
- 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:
- an iterator over the children of this node
getDepth
int getDepth()
- Returns the depth of this node in the valid policy tree.
- Returns:
- the depth of this node (0 for the root node, 1 for its
children, and so on)
getValidPolicy
String getValidPolicy()
- Returns the valid policy represented by this node.
- Returns:
- the
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".
getPolicyQualifiers
Set<? extends PolicyQualifierInfo> getPolicyQualifiers()
- Returns the set of policy qualifiers associated with the
valid policy represented by this node.
- Returns:
- an immutable
Set of
PolicyQualifierInfo s. For the root node, this
is always an empty Set .
getExpectedPolicies
Set<String> getExpectedPolicies()
- Returns the set of expected policies that would satisfy this
node's valid policy in the next certificate to be processed.
- Returns:
- an immutable
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".
isCritical
boolean isCritical()
- Returns the criticality indicator of the certificate policy extension
in the most recently processed certificate.
- Returns:
true if extension marked critical,
false otherwise. For the root node, false
is always returned.
