it is resumed for thread scheduling purposes and receives the object
passed in by the current thread. | | public V | exchange(V x, long timeout, TimeUnit unit)
Waits for another thread to arrive at this exchange point (unless
the current thread is
or

| exchange | | public V exchange(V x) throws InterruptedException(Code) | | Waits for another thread to arrive at this exchange point (unless
the current thread is
),
and then transfers the given object to it, receiving its object
in return.
If another thread is already waiting at the exchange point then
it is resumed for thread scheduling purposes and receives the object
passed in by the current thread. The current thread returns immediately,
receiving the object passed to the exchange by that other thread.
If no other thread is already waiting at the exchange then the
current thread is disabled for thread scheduling purposes and lies
dormant until one of two things happens:
- Some other thread enters the exchange; or
- Some other thread
the current
thread.
If the current thread:
- has its interrupted status set on entry to this method; or
- is
while waiting
for the exchange,
then
InterruptedException is thrown and the current thread's
interrupted status is cleared.
Parameters:
x - the object to exchange the object provided by the other thread
throws:
InterruptedException - if the current thread wasinterrupted while waiting |
| exchange | | public V exchange(V x, long timeout, TimeUnit unit) throws InterruptedException, TimeoutException(Code) | | Waits for another thread to arrive at this exchange point (unless
the current thread is

current thread is disabled for thread scheduling purposes and lies
dormant until one of three things happens:
- Some other thread enters the exchange; or

the current thread; or
- The specified waiting time elapses.
If the current thread:
- has its interrupted status set on entry to this method; or
- is
while waiting
for the exchange,
then

interrupted status is cleared.
If the specified waiting time elapses then
TimeoutException is thrown. If the time is less than or equal
to zero, the method will not wait at all.
Parameters:
x - the object to exchange
Parameters:
timeout - the maximum time to wait
Parameters:
