what is the use of resolveMandatoryClass(String name) in Interface ClassResolver of Apache Camel?

I am new to camel and While reading some code , I found these linesof codes,

String className = "ConvertMapToBeanType";
Class clazz = exchange.getContext().getClassResolver().resolveMandatoryClass(className);

getContext() returns CamelContext.

getClassResolver() Returns the class resolver to be used for loading/lookup of classes.

And what resolveMandatoryClass(className) do? Is this returns Object of the 'className' Class. Is this true, then what is the advantage of creating class like this?

Depending on your runtime environment or configuration you might want to apply different strategies how to load a class by name. The calling code does not care about the strategy as long as it is the right one for the environment. So you provide an interface (e.g., ClassResolver) to the calling code to execute one of several different strategy implementations (e.g., DefaultClassResolver and OsgiClassResolver) to achieve the goal.
