Individual flags are represented by powers of 2. For example, Flag 1 = 1 Flag 2 = 2 Flag 3 = 4 Flag 4 = 8 or using shift operator to make numbering easier: Flag 1 = 1 << 0 Flag 2 = 1 << 1 Flag 3 = 1 << 2 Flag 4 = 1 << 3 There cannot be a flag with a value of 3 because that represents Flag 1 and Flag 2 both being on/true. version:    $Revision: 478334 $ $Date: 2006-11-22 21:31:54 +0000 (Wed, 22 Nov 2006) $ Constructor Summary public   Flags()      Create a new Flags object. public   Flags(long flags)      Initialize a new Flags object with the given flags. Method Summary public  void clear()      Turn off all flags. public  Object clone()      Clone this Flags object. public  boolean equals(Object obj)      Tests if two Flags objects are in the same state. public  long getFlags()      Returns the current flags. public  int hashCode()      The hash code is based on the current state of the flags. public  boolean isOff(long flag)      Tests whether the given flag is off. public  boolean isOn(long flag)      Tests whether the given flag is on. public  String toString()      Returns a 64 length String with the first flag on the right and the 64th flag on the left. public  void turnOff(long flag)      Turns off the given flag. public  void turnOffAll()      Turn off all flags. public  void turnOn(long flag)      Turns on the given flag. public  void turnOnAll()      Turn on all 64 flags. Constructor Detail Flags public Flags()(Code) Create a new Flags object. Flags public Flags(long flags)(Code) Initialize a new Flags object with the given flags. Parameters:   flags - collection of boolean flags to represent. Method Detail clear public void clear()(Code) Turn off all flags. This is a synonym for turnOffAll(). since:    Validator 1.1.1 clone public Object clone()(Code) Clone this Flags object. a copy of this object. See Also:   java.lang.Object.clone equals public boolean equals(Object obj)(Code) Tests if two Flags objects are in the same state. Parameters:   obj - object being tested See Also:   java.lang.Object.equals(java.lang.Object) whether the objects are equal. getFlags public long getFlags()(Code) Returns the current flags. collection of boolean flags represented. hashCode public int hashCode()(Code) The hash code is based on the current state of the flags. See Also:   java.lang.Object.hashCode the hash code for this object. isOff public boolean isOff(long flag)(Code) Tests whether the given flag is off. If the flag is not a power of 2 (ie. 3) this tests whether the combination of flags is off. Parameters:   flag - Flag value to check. whether the specified flag value is off. isOn public boolean isOn(long flag)(Code) Tests whether the given flag is on. If the flag is not a power of 2 (ie. 3) this tests whether the combination of flags is on. Parameters:   flag - Flag value to check. whether the specified flag value is on. toString public String toString()(Code) Returns a 64 length String with the first flag on the right and the 64th flag on the left. A 1 indicates the flag is on, a 0 means it's off. string representation of this object. turnOff public void turnOff(long flag)(Code) Turns off the given flag. If the flag is not a power of 2 (ie. 3) this turns off multiple flags. Parameters:   flag - Flag value to turn off. turnOffAll public void turnOffAll()(Code) Turn off all flags. turnOn public void turnOn(long flag)(Code) Turns on the given flag. If the flag is not a power of 2 (ie. 3) this turns on multiple flags. Parameters:   flag - Flag value to turn on. turnOnAll public void turnOnAll()(Code) Turn on all 64 flags.
