(->reference-queue)Constructor.
Constructs a new reference-object queue.
Constructor. Constructs a new reference-object queue.
pollclj
(poll this)Polls this queue to see if a reference object is available. If one is available without further delay then it is removed from the queue and returned. Otherwise this method immediately returns null.
returns: A reference object, if one was immediately available,
otherwise null - java.lang.ref.Reference<? extends T>
Polls this queue to see if a reference object is available. If one is
available without further delay then it is removed from the queue and
returned. Otherwise this method immediately returns null.
returns: A reference object, if one was immediately available,
otherwise null - `java.lang.ref.Reference<? extends T>`removeclj
(remove this)(remove this timeout)Removes the next reference object in this queue, blocking until either one becomes available or the given timeout period expires.
This method does not offer real-time guarantees: It schedules the timeout as if by invoking the Object.wait(long) method.
timeout - If positive, block for up to timeout milliseconds while waiting for a reference to be added to this queue. If zero, block indefinitely. - long
returns: A reference object, if one was available within the specified
timeout period, otherwise null - java.lang.ref.Reference<? extends T>
throws: java.lang.IllegalArgumentException - If the value of the timeout argument is negative
