| Field Summary | |
| protected char | value_
|
| Constructor Summary | |
| public | SynchronizedChar(char initialValue)
Make a new SynchronizedChar with the given initial value,
and using its own internal lock. | | public | SynchronizedChar(char initialValue, Object lock)
Make a new SynchronizedChar with the given initial value,
and using the supplied lock. |
| value_ | | protected char value_(Code) | | |
| SynchronizedChar | | public SynchronizedChar(char initialValue)(Code) | | Make a new SynchronizedChar with the given initial value,
and using its own internal lock.
|
| SynchronizedChar | | public SynchronizedChar(char initialValue, Object lock)(Code) | | Make a new SynchronizedChar with the given initial value,
and using the supplied lock.
|
| add | | public char add(char amount)(Code) | | Add amount to value (i.e., set value += amount)
the new value |
| commit | | public boolean commit(char assumedValue, char newValue)(Code) | | Set value to newValue only if it is currently assumedValue.
true if successful |
| compareTo | | public int compareTo(char other)(Code) | | |
| divide | | public char divide(char factor)(Code) | | Divide value by factor (i.e., set value /= factor)
the new value |
| get | | final public char get()(Code) | | Return the current value
|
| hashCode | | public int hashCode()(Code) | | |
| multiply | | public synchronized char multiply(char factor)(Code) | | Multiply value by factor (i.e., set value *= factor)
the new value |
| set | | public char set(char newValue)(Code) | | Set to newValue.
the old value |
| subtract | | public char subtract(char amount)(Code) | | Subtract amount from value (i.e., set value -= amount)
the new value |
| swap | | public char swap(SynchronizedChar other)(Code) | | Atomically swap values with another SynchronizedChar.
Uses identityHashCode to avoid deadlock when
two SynchronizedChars 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.)
