accept

Adds a new Node into the current node.

This method is generally considered unsafe, as it allows inserting any kind of node into the current node. Since this library is about representing database requests, this method allows inserting any kind of operation, without necessarily checking any security or coherence invariants.

Users should only interact with this method when they add a new type of node that doesn't exist in the library. For example, when adding an operator that is missing from the library. In these cases, we highly recommend users to contact the maintainers of KtMongo to ensure the created operator respects all invariants. If possible, upstreaming the operator would be of benefit to all users, and guarantees future bug fixes.

In all other cases, it is expected that implementations of this interface provide methods for each added functionality that are responsible for checking invariants and are safe to call.

For a more detailed explanation of the contract of this method, see Node.
