Intent

When objects are expensive to create and they are needed only for short periods of time it is advantageous to utilize the Object Pool pattern. The Object Pool provides a cache for instantiated objects tracking which ones are in use and which are available.

Applicability

Use the Object Pool pattern when

  • the objects are expensive to create (allocation cost)
  • you need a large number of short-lived objects (memory fragmentation)
