Constructors Summary
public PropertyPermission(String name, String actions) Constructs a new instance of this class. param name the (possibly wildcarded) name of the property. param actions the actions which are applicable to it. Possible actions are "read", "write", or "read,write"/"write,read". Anything else will result in an {@code IllegalArgumentException}. since Android 1.0 super(name); decodeActions(actions);

Methods Summary
private void	decodeActions(java.lang.String actions) StringTokenizer tokenizer = new StringTokenizer(Util.toASCIILowerCase(actions), " \t\n\r,"); //$NON-NLS-1$ while (tokenizer.hasMoreTokens()) { String token = tokenizer.nextToken(); if (token.equals("read")) { //$NON-NLS-1$ read = true; } else if (token.equals("write")) { //$NON-NLS-1$ write = true; } else { throw new IllegalArgumentException(); } } if (!read && !write) { throw new IllegalArgumentException(); }
public boolean	equals(java.lang.Object o) Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison. In this case, the receiver must be a {@code PropertyPermission} for the same property as the argument, and must have the same actions. If {@code o} is a permission that is not a {@code PropertyPermission}, this method may throw a {@code ClassCastException}. param o the {@code Object} to compare with this {@code Object}. return {@code true} if the {@code Object} is the same as this {@code Object}, {@code false} if it is different from this {@code Object}. see #hashCode since Android 1.0 if (super.equals(o)) { PropertyPermission pp = (PropertyPermission) o; return read == pp.read && write == pp.write; } return false;
public java.lang.String	getActions() Returns the actions associated with the receiver. The result will be either "read", "write", or "read,write". return the actions associated with the receiver. since Android 1.0 return read ? (write ? "read,write" : "read") : "write"; //$NON-NLS-1$ //$NON-NLS-2$//$NON-NLS-3$
public int	hashCode() Returns an integer hash code for the receiver. Any two objects which return {@code true} when passed to {@code equals} must return the same value for this method. return the receiver's hash. see #equals since Android 1.0 return super.hashCode();
public boolean	implies(java.security.Permission permission) Indicates whether the argument permission is implied by the receiver. return boolean {@code true} if the argument permission is implied by the receiver, and {@code false} if it is not. param permission the permission to check. since Android 1.0 if (super.implies(permission)) { PropertyPermission pp = (PropertyPermission) permission; return (read || !pp.read) && (write || !pp.write); } return false;
public java.security.PermissionCollection	newPermissionCollection() Returns a new {@code PermissionCollection} for holding permissions of this class. Returns {@code null} if any {@code PermissionCollection} can be used. return a new {@code PermissionCollection} or {@code null}. see java.security.PermissionCollection since Android 1.0 return new PropertyPermissionCollection();
private void	readObject(java.io.ObjectInputStream stream) ObjectInputStream.GetField fields = stream.readFields(); String actions = (String) fields.get("actions", ""); //$NON-NLS-1$ //$NON-NLS-2$ decodeActions(actions);
private void	writeObject(java.io.ObjectOutputStream stream) //$NON-NLS-1$ ObjectOutputStream.PutField fields = stream.putFields(); fields.put("actions", getActions()); //$NON-NLS-1$ stream.writeFields();
