Interface DSField

All Known Implementing Classes:

DSFieldImpl

public interface DSField

This interface should be implemented by a class that represents a field number/value pair. The field number defines what data the field represents (e.g. a bid price, or a company name). The value is the actual value for that data (e.g. 53.5, or Caplin Systems Ltd).

• DSData.elements()
• DSData.iterator()
