CompoundBsonNode

interface CompoundBsonNode : BsonNode, CompoundNode<BsonNode> 

A compound expression is an BsonNode that may have children.

A compound expression may have 0..n children. Children are added by calling the accept function.

This is also the supertype for all DSL scopes, since DSL scopes correspond to the ability to add children to an expression.

Implementation notes

Prefer implementing AbstractCompoundBsonNode instead of implementing this interface directly.
