<!-- SPDX-License-Identifier: Apache-2.0 --> # Summary [NIFI-16493](https://issues.apache.org/jira/browse/NIFI-16493) Implements the API portion of [NIP-50](https://issues.apache.org/jira/browse/NIP-50) by adding `patchState(Map<String, String> updatedState, Scope scope)` to `StateManager` and `ProcessSession`. A key with a non-null value is created or overwritten, a key mapped to `null` is removed, and keys not in the map are left unchanged. An empty map does nothing and a `null` map is rejected. - `StateManager.patchState` has a default implementation that retrieves the current state, applies the changes, and calls `replace` until it succeeds. - `ProcessSession.patchState` has no default implementation, so that every session implementation passes the patch through to the framework instead of quietly turning it into a whole-map replacement. `ProcessSession` implementations outside of NiFi will need to add this method. - `NopStateManager` overrides the method, since its `getState` returns `null`. The framework changes are tracked in [NIFI-16494](https://issues.apache.org/jira/browse/NIFI-16494). # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [x] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [x] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [x] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` ### Pull Request Formatting - [x] Pull Request based on current revision of the `main` branch - [x] Pull Request refers to a feature branch with one commit containing changes -- This is an automated message from the Apache Git Service.
