   This library provides classes for dealing with object pooling that allow:

   • blocking/non-blocking object acquisition
   • object invalidation
   • capping the number of pooled objects
   • creating new objects lazily, as needed
   • health checking
   • time-based pool eviction (idle instances)
   • GC-based pool eviction (soft and weak references)
   • efficient thread-safety

   Overview

   In order create a new io.github.andrebeat.pool.Pool the constructor method should be used like so

   scala> val pool = Pool(4, () => new Object)
   pool: io.github.andrebeat.pool.SimplePool[Object] = _
   scala> val lease = pool.acquire()
   lease: io.github.andrebeat.pool.Lease[Object] = _
   scala> lease.release()

   Additionally, in order to avoid manually releasing the lease after its used, you can use the use method on the lease:

   scala> val pool = Pool(4, () => new Object)
   pool: io.github.andrebeat.pool.SimplePool[Object] = _
   scala> val lease = pool.acquire()
   lease: io.github.andrebeat.pool.Lease[Object] = _
   scala> lease(println) // the lease is released automatically after its used
