Overview

Concrete data transfer object representing a single diff entry between two references in the lakeFS Java SDK.

Description

The Diff class is an auto-generated model object produced by OpenAPI Generator from the lakeFS API specification. It provides type-safe access to diff entry fields through getter/setter methods and supports JSON serialization via Gson. It includes TypeEnum (ADDED, REMOVED, CHANGED, CONFLICT, PREFIX_CHANGED) and PathTypeEnum (COMMON_PREFIX, OBJECT) inner enums.

Usage

Use this model when working with diff results from comparing branches, commits, or references through the lakeFS Java SDK API classes.
