Value (Debezium Core 0.9.0.Alpha2 API)

All Superinterfaces:

Comparable<Value>

All Known Implementing Classes:

BinaryValue, ComparableValue, ConvertingValue, NullValue
```
@Immutable
public interface Value
extends Comparable<Value>
```
A value in a Document or Array. Note that compareTo(io.debezium.document.Value, io.debezium.document.Value) might perform literal comparisons; to perform semantic comparisons, use comparable() to obtain a wrapped value with semantic comparison capability.
