  • Method Details

    • setUsageCount

      void setUsageCount(int usageCount)
    • enable

      public boolean enable(T pooled, boolean acquire)
      Enable a reserved entry Pool<T>.Entry. An entry returned from the Pool.reserve() method must be enabled with this method, once and only once, before it is usable by the pool. The entry may be enabled and not acquired, in which case it is immediately available to be acquired, potentially by another thread; or it can be enabled and acquired atomically so that no other thread can acquire it, although the acquire may still fail if the pool has been closed.
      Parameters:
      pooled - The pooled item for the entry
      acquire - If true the entry is atomically enabled and acquired.
      Returns:
      true If the entry was enabled.
      Throws:
      IllegalStateException - if the entry was already enabled
    • getPooled

      public T getPooled()
    • release

      public boolean release()
      Release the entry. This is equivalent to calling Pool.release(Pool.Entry) passing this entry.
      Returns:
      true if released.
    • remove

      public boolean remove()
      Remove the entry. This is equivalent to calling Pool.remove(Pool.Entry) passing this entry.
      Returns:
      true if remove.
    • tryAcquire

      boolean tryAcquire()
      Try to acquire the entry if possible by incrementing both the usage count and the multiplex count.
      Returns:
      true if the usage count is <= maxUsageCount and the multiplex count is maxMultiplex and the entry is not closed, false otherwise.
    • tryRelease

      boolean tryRelease()
      Try to release the entry if possible by decrementing the multiplexing count unless the entity is closed.
      Returns:
      true if the entry was released, false if tryRemove() should be called.
    • tryRemove

      boolean tryRemove()
      Try to remove the entry by marking it as closed and decrementing the multiplexing counter. The multiplexing counter will never go below zero and if it reaches zero, the entry is considered removed.
      Returns:
      true if the entry can be removed from the containing pool, false otherwise.
