Constructor Detail

LocalAtomicBoolean

protected LocalAtomicBoolean(boolean fValue)

Construct LocalAtomicBoolean instance.

Parameters:

fValue - initial value

Method Detail

async

public AsyncLocalAtomicBoolean async()

Description copied from interface: AtomicBoolean

Return non-blocking API for this atomic value.

Specified by:

async in interface AtomicBoolean

Returns:

non-blocking API for this atomic value

get

public boolean get()

Description copied from interface: AtomicBoolean

Returns the current value.

Specified by:

get in interface AtomicBoolean

Returns:

the current value

set

public void set(boolean fNewValue)

Description copied from interface: AtomicBoolean

Sets the value to newValue.

Specified by:

set in interface AtomicBoolean

Parameters:

fNewValue - the new value

getAndSet

public boolean getAndSet(boolean fNewValue)

Description copied from interface: AtomicBoolean

Atomically sets the value to newValue and returns the old value.

Specified by:

getAndSet in interface AtomicBoolean

Parameters:

fNewValue - the new value

Returns:

the previous value

compareAndSet

public boolean compareAndSet(boolean fExpectedValue,
                             boolean fNewValue)

Description copied from interface: AtomicBoolean

Atomically sets the value to newValue if the current value == expectedValue.

Specified by:

compareAndSet in interface AtomicBoolean

Parameters:

fExpectedValue - the expected value

fNewValue - the new value

Returns:

true if successful. False return indicates that the actual value was not equal to the expected value.

compareAndExchange

public boolean compareAndExchange(boolean fExpectedValue,
                                  boolean fNewValue)

Description copied from interface: AtomicBoolean

Atomically sets the value to newValue if the current value, referred to as the witness value, == expectedValue.

Specified by:

compareAndExchange in interface AtomicBoolean

Parameters:

fExpectedValue - the expected value

fNewValue - the new value

Returns:

the witness value, which will be the same as the expected value if successful

toString

public String toString()

Overrides:

toString in class Object
