java.lang.Object

software.amazon.awssdk.enhanced.dynamodb.internal.conditional.SingleKeyItemConditional

All Implemented Interfaces:

QueryConditional

public class SingleKeyItemConditional
extends Object
implements QueryConditional

A QueryConditional implementation that matches values from a specific key using a supplied operator for the sort key value comparison. The partition key value will always have an equivalence comparison applied.

This class is used by higher-level (more specific) QueryConditional implementations such as QueryConditional.sortGreaterThan(Key) to reduce code duplication.
