Example: deep cloning

The Deep Clone pattern creates a copy of an object that is completely separate from the original object, including its properties and sub-properties. Deep cloning is achieved by recursively cloning all the child objects that make up the original object, creating a new instance of each one, and assembling the parent clone from the child clones.

The Deep Clone pattern requires a concept of an object tree, i.e., a concept of a child property. Objects typically have reference properties and child properties, and when deep cloning an object, only child properties should be deep cloned.

Implementing deep cloning can be error-prone and time-consuming, requiring much boilerplate code. This series of articles shows how to automate this work using an aspect, making the code more maintainable and efficient.
