SynchronizedBoolean
public SynchronizedBoolean(boolean initialValue)
Make a new SynchronizedBoolean with the given initial value,
and using its own internal lock.
SynchronizedBoolean
public SynchronizedBoolean(boolean initialValue,
Object lock)
Make a new SynchronizedBoolean with the given initial value,
and using the supplied lock.
and
public boolean and(boolean b)
Set value to value & b.
commit
public boolean commit(boolean assumedValue,
boolean newValue)
Set value to newValue only if it is currently assumedValue.
compareTo
public int compareTo(Object other)
compareTo
public int compareTo(boolean other)
complement
public boolean complement()
Set the value to its complement
equals
public boolean equals(Object other)
get
public final boolean get()
Return the current value
hashCode
public int hashCode()
or
public boolean or(boolean b)
Set value to value | b.
set
public boolean set(boolean newValue)
Set to newValue.
swap
public boolean swap(SynchronizedBoolean other)
Atomically swap values with another SynchronizedBoolean.
Uses identityHashCode to avoid deadlock when
two SynchronizedBooleans attempt to simultaneously swap with each other.
(Note: Ordering via identyHashCode is not strictly guaranteed
by the language specification to return unique, orderable
values, but in practice JVMs rely on them being unique.)
toString
public String toString()
xor
public boolean xor(boolean b)
Set value to value ^ b.
