UnresolvedPermissionCollection

• java.lang.Object
  • java.security.PermissionCollection

Fields Summary
private transient Map	perms Key is permission type, value is a list of the UnresolvedPermissions of the same type. Not serialized; see serialization section at end of class.
private static final long	serialVersionUID
private static final ObjectStreamField[]	serialPersistentFields

Constructors Summary
public UnresolvedPermissionCollection() Create an empty UnresolvedPermissionCollection object. perms = new HashMap(11);

Methods Summary
public void	add(java.security.Permission permission) Adds a permission to this UnresolvedPermissionCollection. The key for the hash is the unresolved permission's type (class) name. param permission the Permission object to add. if (! (permission instanceof UnresolvedPermission)) throw new IllegalArgumentException("invalid permission: "+ permission); UnresolvedPermission up = (UnresolvedPermission) permission; List v; synchronized (this) { v = (List) perms.get(up.getName()); if (v == null) { v = new ArrayList(); perms.put(up.getName(), v); } } synchronized (v) { v.add(up); }
public java.util.Enumeration	elements() Returns an enumeration of all the UnresolvedPermission lists in the container. return an enumeration of all the UnresolvedPermission objects. List results = new ArrayList(); // where results are stored // Get iterator of Map values (which are lists of permissions) synchronized (this) { for (Iterator iter = perms.values().iterator(); iter.hasNext();) { List l = (List) iter.next(); synchronized (l) { results.addAll(l); } } } return Collections.enumeration(results);
java.util.List	getUnresolvedPermissions(java.security.Permission p) get any unresolved permissions of the same type as p, and return the List containing them. synchronized (this) { return (List) perms.get(p.getClass().getName()); }
public boolean	implies(java.security.Permission permission) always returns false for unresolved permissions return false;
private void	readObject(java.io.ObjectInputStream in) // Don't call defaultReadObject() // Read in serialized fields ObjectInputStream.GetField gfields = in.readFields(); // Get permissions Hashtable permissions = (Hashtable)gfields.get("permissions", null); perms = new HashMap(permissions.size()*2); // Convert each entry (Vector) into a List Set set = permissions.entrySet(); for (Iterator iter = set.iterator(); iter.hasNext(); ) { Map.Entry e = (Map.Entry)iter.next(); // Convert Vector into ArrayList Vector vec = (Vector) e.getValue(); List list = new ArrayList(vec.size()); list.addAll(vec); // Add to Hashtable being serialized perms.put(e.getKey(), list); }
private void	writeObject(java.io.ObjectOutputStream out) serialData Default field. /* * Writes the contents of the perms field out as a Hashtable * in which the values are Vectors for * serialization compatibility with earlier releases. */ // Don't call out.defaultWriteObject() // Copy perms into a Hashtable Hashtable permissions = new Hashtable(perms.size()*2); // Convert each entry (List) into a Vector synchronized (this) { Set set = perms.entrySet(); for (Iterator iter = set.iterator(); iter.hasNext(); ) { Map.Entry e = (Map.Entry)iter.next(); // Convert list into Vector List list = (List) e.getValue(); Vector vec = new Vector(list.size()); synchronized (list) { vec.addAll(list); } // Add to Hashtable being serialized permissions.put(e.getKey(), vec); } } // Write out serializable fields ObjectOutputStream.PutField pfields = out.putFields(); pfields.put("permissions", permissions); out.writeFields();
