Interface JsonPatchValueTransformer

public interface JsonPatchValueTransformer

RFC6902 expects the patch value to be a predetermined, static value to be used in the patch operation's execution. This class provides a means to extend that behavior to allow for values that require transformation based on the patch target document. This impl is the default used by JsonPatch but may be overridden by calling JsonPatch.patch(JsonValue original, JsonValue patch, JsonPatchValueTransform custom).
