Calling this method on an element value tells the proxy that the value for this element maps to the specified field in the specified table. The proxy then checks if the field must be encrypted. If the table and field names are unknown, you can call the valueFor() method on a table and a field that are dynamically assigned based on the request.

Calling this function on an element tells the proxy that the value of the element is an encoded query for the specified table. The proxy parses the encoded query and encrypts the fields in the encoded query that must be encrypted.
