@Transform - add option to skip the circular check about class-transformer

[cojack]

@geleto any example of use case?

[geleto]

I have a @RefById() transform decorator which rather than serializing the object - stores just the id of the object. When deserializing, the id is used to transparently set the reference to the existing object. Because of this, the transform does not need to be checked for circular references.

While I can use a getter/setter that does the id reference, this is not as clear and simple and my code would be littered with such getters/setters.

My implementation was probably a bit too complex, I modified a few things in class-transformer. One was disabling the circular checks. Another was supplying the parent object to transformFn - if the referenced object does not exist yet when deserializing, it would be assigned later when it is constructed, for which I needed to store the parent object.

Maybe what class-transformer actually needs is the ability to serialize/deserialize references to objects.

Hi @geleto!

You can control circular check via enableCircularCheck in the third parameter of classToPlain.
