QueryConditional (AWS Java SDK :: DynamoDB :: Enhanced Client 2.17.175 API)

All Known Implementing Classes:

BeginsWithConditional, BetweenConditional, EqualToConditional, SingleKeyItemConditional
```
@ThreadSafe
public interface QueryConditional
```
An interface for a literal conditional that can be used in an enhanced DynamoDB query. Contains convenient static methods that can be used to construct the most common conditional statements. Query conditionals are not linked to any specific table or schema and can be re-used in different contexts.
Example:
```
 
 QueryConditional sortValueGreaterThanFour = QueryConditional.sortGreaterThan(k -> k.partitionValue(10).sortValue(4));
 
 
```
