Enclosing interface:

JsonPatch

public static enum JsonPatch.Operation
extends Enum<JsonPatch.Operation>

An enumeration of available operations for JsonPatch.

Enum Constant Detail

ADD

public static final JsonPatch.Operation ADD

required members are:

• "op": "add"
• "path": "path/to/add"
• "value": "JsonValueToAdd"

if the "path/to" does not exist, this operation will result in an error.
if the "path/to/add" already exists, the value will be replaced

for JsonArrays the new value will be inserted at the specified index and the element(s) at/after are shifted to the right. the '-' character is used to append the value at the and of the JsonArray.

REMOVE

public static final JsonPatch.Operation REMOVE

required members are:

• "op": "remove"
• "path": "path/to/remove"

if the "path/to/remove" does not exist, the operation will fail.

for JsonArrays the values after the removed value are shifted to the left

REPLACE

public static final JsonPatch.Operation REPLACE

required members are:

• "op": "replace"
• "path": "path/to/replace"
• "value": "the new JsonValue"

this operation is identical to REMOVE followed by ADD

MOVE

public static final JsonPatch.Operation MOVE

required members are:

• "op": "move"
• "from": "path/to/move/from"
• "path": "path/to/move/to"

the operation will fail it the "path/to/move/from" does not exist

NOTICE: a location can not be moved into one of it's children. (from /a/b/c to /a/b/c/d)

this operation is identical to REMOVE from "from" and ADD to the "path"

COPY

public static final JsonPatch.Operation COPY

required members are:

• "op": "copy"
• "from": "path/to/copy/from"
• "path": "path/to/add"

the operation will result in an error if the "from" location does not exist

this operation is identical to ADD with the "from" value

TEST

public static final JsonPatch.Operation TEST

required members are:

• "op": "test"
• "path": "/path/to/test"
• "value": "JsonValue to test"

this operation fails, if the value is NOT equal with the /path/to/test

ordering of the elements in a JsonObject is NOT significant however the position of an element in a JsonArray is significant for equality.

Method Detail

values

public static JsonPatch.Operation[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (JsonPatch.Operation c : JsonPatch.Operation.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static JsonPatch.Operation valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

operationName

public String operationName()

Returns:

the JSON operation name

fromOperationName

public static JsonPatch.Operation fromOperationName(String operationName)

Returns the JsonPatch.Operation for the given operationName. If no JsonPatch.Operation is present, a JsonException will be thrown.

Parameters:

operationName - operationName to convert to the enum constant.

Returns:

the Operation-constant for given operationName

Throws:

JsonException - if no JsonPatch.Operation has been found for the given operationName
