BsonNode

interface BsonNode : Node

A node in the BSON AST.

Each implementation of this interface is a logical BSON node in our own intermediary representation. Each node knows how to writeTo itself into a BSON document.

Security

Implementing this interface allows injecting arbitrary BSON into a request. Be very careful not to make injections possible.

Implementation notes

Prefer implementing AbstractBsonNode instead of implementing this interface directly.

Debugging notes

Use toString to view the JSON representation of this expression.
