Implements

JsonSerializable<JsonPatchDocument>

public final class JsonPatchDocument
implements JsonSerializable<JsonPatchDocument>

Represents a JSON Patch document.

This class encapsulates a list of JsonPatchOperation instances that form a JSON Patch document. It provides methods to add various types of operations (add, replace, copy, move, remove, test) to the document.

Each operation in the document is represented by a JsonPatchOperation instance, which encapsulates the operation kind, path, and optional from and value.

This class also provides a toJson(JsonWriter jsonWriter) method to serialize the JSON Patch document to JSON, and a fromJson(JsonReader jsonReader) method to deserialize a JSON Patch document from JSON.

This class is useful when you want to create a JSON Patch document to express a sequence of operations to apply to a JSON document.

Constructor Details

JsonPatchDocument

public JsonPatchDocument()

Creates a new JSON Patch document.

JsonPatchDocument

public JsonPatchDocument(JsonSerializer serializer)

Creates a new JSON Patch document.

If serializer isn't specified JacksonAdapter will be used.

Parameters:

serializer - The JsonSerializer that will be used to serialize patch operation values.

Method Details

appendAdd

public JsonPatchDocument appendAdd(String path, Object value)

Appends an "add" operation to this JSON Patch document.

If the path doesn't exist a new member is added to the object. If the path does exist the previous value is replaced. If the path specifies an array index the value is inserted at the specified.

See JSON Patch Add for more information.

Code Samples

/*
  * Add an object member to the JSON document { "foo" : "bar" } to get the JSON document
  * { "bar": "foo", "foo": "bar" }.
  */

 /*
  * Add an array element to the JSON document { "foo": [ "fizz", "fizzbuzz" ] } to get the JSON document
  * { "foo": [ "fizz", "buzz", "fizzbuzz" ] }.
  */
 jsonPatchDocument.appendAdd("/foo/1", "buzz");

 /*
  * Add a nested member to the JSON document { "foo": "bar" } to get the JSON document
  * { "foo": "bar", "child": { "grandchild": { } } }.
  */

Returns:

The updated JsonPatchDocument object.

appendAddRaw

public JsonPatchDocument appendAddRaw(String path, String rawJson)

Appends an "add" operation to this JSON Patch document.
