    • tryEnable

      protected boolean tryEnable(boolean acquire)
      Description copied from class: Pool.Entry

      Tries to enable, and possible also acquire, this Entry.

      whether this Entry was enabled

    • tryAcquire

      boolean tryAcquire()

      Tries to acquire the entry if possible by incrementing both the usage count and the multiplex count.

      Specified by:
      tryAcquire in class Pool<T>.Entry
      Returns:
      true if the usage count is less than Pool.getMaxUsageCount() and the multiplex count is less than Pool.getMaxMultiplex(Object) and the entry is not closed, false otherwise.

    • tryRelease

      boolean tryRelease()

      Tries to release the entry if possible by decrementing the multiplex count unless the entity is closed.

      Specified by:
