Class XMLPolicyParser.RoleListNode

java.lang.Object
  issrg.pba.rbac.xmlpolicy.PolicyXMLNode
      issrg.pba.rbac.xmlpolicy.XMLPolicyParser.RoleListNode

Enclosing class:

XMLPolicyParser

public class XMLPolicyParser.RoleListNode
extends PolicyXMLNode

This is an implementation of Role List. The object constructs the credential the Role List represents. It uses a RoleHierarchyPolicyNode to identify the roles listed.

Version:

1.0

Author:

A Otenko

Field Summary

protected Credentials	credential This is the credential, represented by the Role List.
protected XMLPolicyParser.RoleHierarchyPolicyNode	policy This is the reference to the Role Hierarchy Policy

Constructor Summary

XMLPolicyParser.RoleListNode(org.xml.sax.Attributes attrs)
This constructor builds a RoleListNode given the set of attributes.

XMLPolicyParser.RoleListNode(XMLPolicyParser.RoleHierarchyPolicyNode rhpn, org.xml.sax.Attributes attrs)
This constructor builds a RoleListNode given the RoleHierarchyPolicy and the attributes of the XML element.

Method Summary

void	construct() This method checks that all the roles listed have been declared in the corresponding RoleHierarchyPolicyNode and constructs a Credentials representing the union of all the roles in the list.
Credentials	getCredential() This method returns the credential this role list represents

Field Detail

policy

protected XMLPolicyParser.RoleHierarchyPolicyNode policy

This is the reference to the Role Hierarchy Policy

credential

protected Credentials credential

This is the credential, represented by the Role List.

Constructor Detail

XMLPolicyParser.RoleListNode

public XMLPolicyParser.RoleListNode(org.xml.sax.Attributes attrs)

This constructor builds a RoleListNode given the set of attributes. It uses the default RoleHierarchyPolicy that must be discovered by XMLPolicyParser by the time of constructing this Role List.

This is a shortcut to calling new RoleListNode(null, attrs).

Parameters:

attrs - - the attributes of this XML element

XMLPolicyParser.RoleListNode

public XMLPolicyParser.RoleListNode(XMLPolicyParser.RoleHierarchyPolicyNode rhpn,
                                    org.xml.sax.Attributes attrs)

This constructor builds a RoleListNode given the RoleHierarchyPolicy and the attributes of the XML element.

Parameters:

rhpn - - RoleHierarchyPolicyNode representing the role hierarchy policy to be used by this Role List; if null, the default RoleHierarchyPolicy discovered by XMLPolicyParser will be used

attrs - - the attributes of the XML element

Method Detail

construct

public void construct()
               throws PolicyParsingException

This method checks that all the roles listed have been declared in the corresponding RoleHierarchyPolicyNode and constructs a Credentials representing the union of all the roles in the list. The validityForRoleList is assumed to have been set by XMLPolicyParser, but this is not always so (because of the sequence of policy parsing), so the RoleAssignmentPolicyNode invokes this method again after the validity of the roles has been discovered.

Overrides:

construct in class PolicyXMLNode

Throws:

PolicyParsingException - if any syntax or semantics error occurred

getCredential

public Credentials getCredential()

This method returns the credential this role list represents
