Constructors Summary
public Flags() Construct an empty Flags object.
public Flags(Flags flags) Construct a Flags object initialized with the given flags. param flags the flags for initialization this.system_flags = flags.system_flags; if (flags.user_flags != null) this.user_flags = (Hashtable)flags.user_flags.clone();
public Flags(Flag flag) Construct a Flags object initialized with the given system flag. param flag the flag for initialization this.system_flags |= flag.bit;
public Flags(String flag) Construct a Flags object initialized with the given user flag. param flag the flag for initialization user_flags = new Hashtable(1); user_flags.put(flag.toLowerCase(Locale.ENGLISH), flag);

Methods Summary
public void	add(javax.mail.Flags$Flag flag) Add the specified system flag to this Flags object. param flag the flag to add system_flags |= flag.bit;
public void	add(java.lang.String flag) Add the specified user flag to this Flags object. param flag the flag to add if (user_flags == null) user_flags = new Hashtable(1); user_flags.put(flag.toLowerCase(Locale.ENGLISH), flag);
public void	add(javax.mail.Flags f) Add all the flags in the given Flags object to this Flags object. param f Flags object system_flags |= f.system_flags; // add system flags if (f.user_flags != null) { // add user-defined flags if (user_flags == null) user_flags = new Hashtable(1); Enumeration e = f.user_flags.keys(); while (e.hasMoreElements()) { String s = (String)e.nextElement(); user_flags.put(s, f.user_flags.get(s)); } }
