Syntax
public class DecoratorBasedServiceResolutionInfo
Remarks

A service created using the decorator pattern is a series of service objects, each wrapping the one which precedes it. See https://en.wikipedia.org/wiki/Decorator_pattern for more info but a good analogy are Russian Matryoshka dolls, each doll contains another. Likewise, with services created using the decorator pattern, each object which implements the service interface wraps another object that implements the same interface. Only one object in the overall service does not wrap an object of the same interface.

To create a service that uses the decorator pattern a queue of services-to-resolve is specified. When resolving each of these services, that resolved object is passed as a dependency to the resolution of the next service in the queue.
