Etymology
RecordFieldId gives the identification of a field in a record.
Synopsis
This class provides the user to identify a field in a record. Identification can be done by means of the field name or by means of its field number.
For the programmer the most convenient way is probably the name, because that is the natural identification. However, identification by means of field number is much faster and could be used when it is known.
Example
void someFunc (const Record& record)
{
float value1 = record.asfloat ("name");
float value2 = record.asfloat (0);
}
Motivation
This class makes it possible that many functions in Record classes have to be defined only once. The constructors of RecordFieldId make it possible that a number and a string are automatically converted, so the user does not have to instantiate a RecordFieldId object explicitly.
