PolicyNode (moe.ios.core API)

All Known Implementing Classes:

PKIXPolicyNode
```
public interface PolicyNode
```
The interface to a valid policy tree node for the PKIX certification path validation algorithm.
Instances of this class are one of the outputs of the PKIX certification path validation algorithm.

- Method Detail
  - getChildren
```
Iterator<? extends PolicyNode> getChildren()
```
    Returns the list of children of this node as an Iterator.
    
    Returns:
    
    the list of children of this node as an Iterator.
  - getDepth
```
int getDepth()
```
    Returns the depth of this node in the policy tree.
    the depth is zero based.
    
    Returns:
    
    the depth of this node in the policy tree.
  - getExpectedPolicies
```
Set<String> getExpectedPolicies()
```
    Returns the expected policies for the next certificate to be valid.
    
    Returns:
    
    the expected policies.
  - getParent
```
PolicyNode getParent()
```
    Returns the parent policy node.
    
    Returns:
    
    the parent policy node.
  - getPolicyQualifiers
```
Set<? extends PolicyQualifierInfo> getPolicyQualifiers()
```
    Returns the policy qualifiers associated with the policy of this node.
    
    Returns:
    
    the policy qualifiers associated with the policy of this node.
  - getValidPolicy
```
String getValidPolicy()
```
    Returns the valid policy of this node.
    
    Returns:
    
    the valid policy of this node.
  - isCritical
```
boolean isCritical()
```
    Returns whether the certificate policy extension of the most recently processed certificate is marked as critical.
    
    Returns:
    
    true if the extension is marked as critical, otherwise false.
