3️⃣#Object_Pool_Design_Pattern

👉Intent

Object pooling can offer a significant performance boost; it is most effective in situations where the cost of initializing a class instance is high, the rate of instantiation of a class is high, and the number of instantiations in use at any one time is low.

#Prototype_Design_Pattern

👉Intent

Specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype.
Co-opt one instance of a class for use as a breeder of all future instances.
The new operator considered harmful.

👉Creational patterns

In software engineering, creational design patterns are design patterns that deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. The basic form of object creation could result in design problems or added complexity to the design. Creational design patterns solve this problem by somehow controlling this object creation.


1️⃣ #Abstract_Factory_Design_Pattern

▪️Creates an instance of several families of classes

2️⃣ #Builder_Design_Pattern

▪️Separates object construction from its representation
3️⃣ #Factory_Method_Design_Pattern

▪️Creates an instance of several derived classes

4️⃣ #Object_Pool_Design_Pattern

▪️Avoid expensive acquisition and release of resources by recycling objects that are no longer in use

5️⃣ #Prototype_Design_Pattern

▪️A fully initialized instance to be copied or cloned

6️⃣ #Singleton_Design_Pattern

▪️A class of which only a single instance can exist
