AtomicBoolean
public class AtomicBoolean implements java.io.Serializable(Code)
A boolean value that may be updated atomically. See the java.util.concurrent.atomic package specification for description of the properties of atomic variables. An AtomicBoolean is used in applications such as atomically updated flags, and cannot be used as a replacement for a java.lang.Boolean .

Constructor Summary
public  AtomicBoolean(boolean initialValue)
     Creates a new AtomicBoolean with the given initial value.
public  AtomicBoolean()
     Creates a new AtomicBoolean with initial value false.

Method Summary
final public  booleancompareAndSet(boolean expect, boolean update)
     Atomically sets the value to the given update value if the current value is equal to the expected value.
final public  booleanget()
     Returns the current value.
final public  booleangetAndSet(boolean newValue)
     Sets to the given value and returns the previous value.
final public  voidset(boolean newValue)
     Unconditionally sets to the given value.
public  StringtoString()
     Returns the String representation of the current value.
public  booleanweakCompareAndSet(boolean expect, boolean update)
     Atomically set the value to the given updated value if the current value == the expected value.


Constructor Detail
AtomicBoolean
public AtomicBoolean(boolean initialValue)(Code)
Creates a new AtomicBoolean with the given initial value.
Parameters:
  initialValue - the initial value



AtomicBoolean
public AtomicBoolean()(Code)
Creates a new AtomicBoolean with initial value false.




Method Detail
compareAndSet
final public boolean compareAndSet(boolean expect, boolean update)(Code)
Atomically sets the value to the given update value if the current value is equal to the expected value. Any given invocation of this operation may fail (return false) spuriously, but repeated invocation when the current value holds the expected value and no other thread is also attempting to set the value will eventually succeed.
Parameters:
  expect - the expected value
Parameters:
  update - the new value true if successful



get
final public boolean get()(Code)
Returns the current value. the current value



getAndSet
final public boolean getAndSet(boolean newValue)(Code)
Sets to the given value and returns the previous value.
Parameters:
  newValue - the new value the previous value



set
final public void set(boolean newValue)(Code)
Unconditionally sets to the given value.
Parameters:
  newValue - the new value



toString
public String toString()(Code)
Returns the String representation of the current value. the String representation of the current value.



weakCompareAndSet
public boolean weakCompareAndSet(boolean expect, boolean update)(Code)
Atomically set the value to the given updated value if the current value == the expected value. May fail spuriously.
Parameters:
  expect - the expected value
Parameters:
  update - the new value true if successful.
