How does an object pool create an object?
When a client program requests a new object, the object pool first attempts to provide one that has already been created and returned to the pool. If none is available, only then is a new object created.
How to test object pool in C + +?
The sample is an application that keeps creating and deleting 100 objects 1 million times, then it shows how much time it takes to finish the job, using the pool and using normal new and delete calls. Of course this is not a real situation, but it shows how fast the pool can be compared to normal new/delete calls.
How does an object pool improve application performance?
Object pools can improve application performance in situations where you require multiple instances of a class and the class is expensive to create or destroy. When a client program requests a new object, the object pool first attempts to provide one that has already been created and returned to the pool.
How is an object returned from a pool?
When the application requests an object, and the object is available from the pool, it is returned from the pool. If the object of the requested type is not available from the pool, then a new instance of the object is created and returned. When the application no longer needs the object, the object is sent back to the pool.
Is the object pooling technique a deprecated technique?
The answer to the concrete question: ‘Is object pooling a deprecated technique?’ is: No. Object pooling is widely used in specific places – thread pooling, database connection pooling etc. General object creation has never been a slow process. Pooling in itself consumes resources – memory and processing power.
Which is the best object pooling design pattern?
