- - ### Constructor Detail

    - #### PooledSoftReference

          public PooledSoftReference(SoftReference<T> reference)

      Creates a new PooledSoftReference wrapping the provided reference.
      Parameters:
        `reference` - SoftReference to be managed by the pool

  - ### Method Detail

    - #### getObject

          public T getObject()

      Returns the object that the wrapped SoftReference refers to.

      Note that if the reference has been cleared, this method will return null.

      Specified by:
        `getObject` in interface `PooledObject<T>`
      Overrides:
        `getObject` in class `DefaultPooledObject<T>`
      Returns:
        Object referred to by the SoftReference

    - #### toString

          public String toString()

      Provides a String form of the wrapper for debug purposes. The format is not fixed and may change at any time.

      Specified by:
        `toString` in interface `PooledObject<T>`
      Overrides:
        `toString` in class `DefaultPooledObject<T>`

    - #### getReference

          public SoftReference<T> getReference()

      Returns the SoftReference wrapped by this object.
      Returns:
        underlying SoftReference

    - #### setReference

          public void setReference(SoftReference<T> reference)

      Sets the wrapped reference.

      This method exists to allow a new, non-registered reference to be held by the pool to track objects that have been checked out of the pool. The actual parameter should be a reference to the same object that `getObject()` returns before calling this method.

      Parameters:
        `reference` - new reference
