Class JsonDiff

java.lang.Object

com.github.fge.jsonpatch.diff.JsonDiff

@ParametersAreNonnullByDefault
public final class JsonDiff
extends Object

JSON "diff" implementation

This class generates a JSON Patch (as in, an RFC 6902 JSON Patch) given two JSON values as inputs. The patch can be obtained directly as a JsonPatch or as a JsonNode.

Note: there is no guarantee about the usability of the generated patch for any other source/target combination than the one used to generate the patch.

This class always performs operations in the following order: removals, additions and replacements. It then factors removal/addition pairs into move operations, or copy operations if a common element exists, at the same pointer, in both the source and destination.

You can obtain a diff either as a JsonPatch directly or, for backwards compatibility, as a JsonNode.
