TMongoExpression is a generic base class. Please do not use it directly in your applications.
The API of this class is equivalent to the TMongoDocument API, and adds only two new methods:
- TMongoExpression.End: Finishes this stage or operation, and returns a reference to the parent object of this expression.
- TMongoExpression.Exp: Appends the specified field and expression to this expression, and returns a reference to this expression.
