Class XMLPolicyParser.RoleAssignmentPolicyNode

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

Enclosing class:

XMLPolicyParser

public class XMLPolicyParser.RoleAssignmentPolicyNode
extends PolicyXMLNode

This node implements the RoleAssignmentPolicy XML node. It is intelligent enough to walk through its children and retrieve all the information to build an index of AssignmentRule vectors by SOA DNs.

Constructor Detail

XMLPolicyParser.RoleAssignmentPolicyNode

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

This constructor builds a RoleAssingmentPolicyNode, given the attributes of the XML element. It uses the Subject Policy and SOA Policy constructed by XMLPolicyParser, so these must already be known at the time of constructing the object.

Parameters:

attrs - - the attributes of this XML element

XMLPolicyParser.RoleAssignmentPolicyNode

public XMLPolicyParser.RoleAssignmentPolicyNode(XMLPolicyParser.DomainPolicyNode subjectPolicy,
                                                XMLPolicyParser.SOAPolicyNode soaPolicy,
                                                org.xml.sax.Attributes attrs)

This constructor builds the object from explicitly specified Subject Policy, SOA Policy and the attributes of the XML element.

Parameters:

subjectPolicy - - the Subject Policy to be used

soaPolicy - - the SOA Policy to be used

attrs - - the attributes of this XML element

Method Detail

construct

public void construct()
               throws PolicyParsingException

This method finishes the construction of the Role Assignment Policy. During this process it checks that the right XML statements appear in the policy and in the correct sequence. It checks that the SOA and the Subject domain with the specified IDs have been declared in the corresponding policies.

Overrides:

construct in class PolicyXMLNode

Throws:

PolicyParsingException - if any syntax or semantics error occurred

getRules

public java.util.Map getRules()

This method returns the rules defined by the appropriate XML node. The rules contain Vectors of issrg.pba.rbac.policies.AssignmentRule objects, indexed by the SOA name. There also is a special entry with the key issrg.pba.rbac.policies.Subtree.class: its value is a issrg.pba.rbac.policies.Subtree of the coverage domain of the Subject Policy.

parseDateTime

protected RelativeDate parseDateTime(java.lang.String s)

This routine parses the string in format ccyy-mm-ddThh:mm:ss and separates it into the integers. The syntax is not strict, so any nymber of subsequent digits is allowed, and any non-digit characters can be used as separators (the parser does not ensure the separators are "-", "T", ":", and that they are used in that order).

Examples:

"00000002~73|1" is parsed as year 2, month 73, day 1. Note that the actual meaning depends on where this statement is used. If it is the Absolute date specification, then it is equal to "8-1-1" (73 months is the same as 6 more years and 1 month).

"2002-12-31T12:00:21:567" - the last term ":567" is ignored.

Parameters:

s - is the string of format "ccyy-mm-ddThh:mm:ss" to parse

Returns:

a RelativeDate object with appropriate integers assigned
