Interface FieldAdapter
-
- All Known Implementing Classes:
BitFieldAdapter,DefaultFieldAdapter,DoubleBinaryFieldAdapter,FloatBinaryFieldAdapter,IntegerBinaryFieldAdapter,NumericTextFieldAdapter
public interface FieldAdapterDefines an adapter object for table fields that can read the field value from a byte array or write the field value into a byte array. Also has methods for formatting the value into an output writer for either delimited or fixed-width output. Methods not appropriate for the field type will throwUnsupportedOperationException.
