Interface Tuple.TupleFormatter

All Known Implementing Classes:
Tuple.DefaultTupleFormatter
Enclosing class:
Tuple
public static interface Tuple.TupleFormatter
This interface is not public API, and should not be implemented by users. Use the default StreamBase implementation via Tuple.getTupleFormatter() or customize your formatter by subclassing Tuple.DefaultTupleFormatter instead.

Used to format tuple fields, by converting a StreamBase field's value to a string. TupleFormatters must handle the case for when the given value is null, but should never return null.
