  • Method Details

    • createNullPolicy

      public static Policy createNullPolicy()
      The factory method creates an immutable policy instance which represents a 'nothing allowed' policy expression. The policy is created using the latest namespace version supported.
      Returns:
      policy instance which represents a 'nothing allowed' (no policy alternatives).

    • createEmptyPolicy

      public static Policy createEmptyPolicy()
      The factory method creates an immutable policy instance which represents a 'anything allowed' policy expression. The policy is created using the latest namespace version supported.
      Returns:
      policy instance which represents a 'anything allowed' (empty policy alternative with no plicy assertions prescribed).

    • createNullPolicy

      public static Policy createNullPolicy(String name, String policyId)
      The factory method creates an immutable policy instance which represents a 'nothing allowed' policy expression. The policy is created using the latest namespace version supported.
      Parameters:
      name - global URI of the policy. May be null.
      policyId - local URI of the policy. May be null.
      Returns:
      policy instance which represents a 'nothing allowed' (no policy alternatives).

    • createNullPolicy

      public static Policy createNullPolicy(NamespaceVersion nsVersion, String name, String policyId)
      The factory method creates an immutable policy instance which represents a 'nothing allowed' policy expression. The policy is created using the latest namespace version supported.
      Parameters:
      nsVersion - Policy namespace version to be used when marshalling the policy expression
      name - global URI of the policy. May be null.
      policyId - local URI of the policy. May be null.
      Returns:
      policy instance which represents a 'nothing allowed' (no policy alternatives).

    • createEmptyPolicy

      public static Policy createEmptyPolicy(String name, String policyId)
      The factory method creates an immutable policy instance which represents a 'anything allowed' policy expression. The policy is created using the latest namespace version supported.
      Parameters:
      name - global URI of the policy. May be null.
      policyId - local URI of the policy. May be null.
      Returns:
      policy instance which represents a 'anything allowed' (empty policy alternative with no plicy assertions prescribed).

    • createEmptyPolicy

      public static Policy createEmptyPolicy(NamespaceVersion nsVersion, String name, String policyId)
      The factory method creates an immutable policy instance which represents a 'anything allowed' policy expression. The policy is created using the latest namespace version supported.
      Parameters:
      nsVersion - Policy namespace version to be used when marshalling the policy expression
      name - global URI of the policy. May be null.
      policyId - local URI of the policy. May be null.
      Returns:
      policy instance which represents a 'anything allowed' (empty policy alternative with no plicy assertions prescribed).

    • createPolicy

      public static Policy createPolicy(Collection<AssertionSet> sets)
      The factory method creates an immutable policy instance which represents a policy expression with alternatives specified by sets input parameter. If the collection of policy alternatives is null or empty an object representing a 'NULL' policy expression is returned. However, in such case it is better to use createNullPolicy() factory method directly. The policy is created using the latest namespace version supported.
      Parameters:
      sets - represents the collection of policy alternatives of the policy object created. During the creation of the new policy object, the content of the alternatives collection is copied into an internal policy object structure, thus any subsequent operations on the collection will have no impact on the newly constructed policy object.
      Returns:
      policy instance which represents the policy with given alternatives.

    • createPolicy

      public static Policy createPolicy(String name, String policyId, Collection<AssertionSet> sets)
      The factory method creates an immutable policy instance which represents a policy expression with alternatives specified by sets input parameter. If the collection of policy alternatives is null or empty an object representing a 'NULL' policy expression is returned. However, in such case it is better to use createNullPolicy(String, String) factory method directly. The policy is created using the latest namespace version supported.
      Parameters:
      name - global URI of the policy. May be null.
      policyId - local URI of the policy. May be null.
      sets - represents the collection of policy alternatives of the policy object created. During the creation of the new policy object, the content of the alternatives collection is copied into an internal policy object structure, thus any subsequent operations on the collection will have no impact on the newly constructed policy object.
      Returns:
      policy instance which represents the policy with given alternatives.

    • createPolicy

      public static Policy createPolicy(NamespaceVersion nsVersion, String name, String policyId, Collection<AssertionSet> sets)
      The factory method creates an immutable policy instance which represents a policy expression with alternatives specified by sets input parameter. If the collection of policy alternatives is null or empty an object representing a 'NULL' policy expression is returned. However, in such case it is better to use createNullPolicy(String, String) factory method directly. The policy is created using the latest namespace version supported.
      Parameters:
      nsVersion - Policy namespace version to be used when marshalling the policy expression
      name - global URI of the policy. May be null.
      policyId - local URI of the policy. May be null.
      sets - represents the collection of policy alternatives of the policy object created. During the creation of the new policy object, the content of the alternatives collection is copied into an internal policy object structure, thus any subsequent operations on the collection will have no impact on the newly constructed policy object.
      Returns:
      policy instance which represents the policy with given alternatives.

      Retrieves the vocabulary of this policy expression. The vocabulary is represented by an immutable collection of unique QName objects. Each of those objects represents single assertion type contained in the policy.
      Returns:
      immutable collection of assertion types contained in the policy (a policy vocabulary).

    • contains
