Class: Status

What​

The abstract Status class provides methods to create a new Status object based on an existing Status Code.

Status codes are defined by creating an Resource Status Definition Asset within your Project. Within this Asset you can create one or more Vendors which in turn may have a number of Status entries.

Each of those Status entries has the following structure:

  • ID: A unique number
  • Logical name: A name which uniquely identifies a Status, e.g. FIELD_UNKNOWN
  • Language: One of the supported language codes, e.g. en
  • Message: The actual Status message. The message may contain placeholders, e.g. The field with name %1 is unknown. In this example, the placeholder %1 is filled with the respective value when creating the Status using method Status.create.

How to use​

Based on the Vendor and the logical status name which you have defined, you can create a new Status. The Status can then be attached to a message or a passed as a result code when rolling back a stream (example).

Properties​

code​

code: number

The code of the Status which was assigned when the Status was created.

Example​

// Create a new Status
const status = Status.create(VENDOR, 42);
// Get the code
const c = status.code; // returns 42

message​

message: string

The message of the Status which was assigned when the Status was created. The message may contain placeholders which can be filled with parameters when creating the Status. Same as getMessage.

Example​

// Create a new Status
const status = Status.create(VENDOR, 'ILLEGAL_VALUE', 'LastName', 'Putin');
// Get the message
const m = status.message; // returns "Field with name '%1' contains illegal value '%2'"

parameters​

parameters: string[]

The parameters which were passed when the Status was created. These parameters are used to fill in placeholders in the message. Same as getParameters.

Example​

// Create a new Status
const status = Status.create(VENDOR, 'ILLEGAL_VALUE', 'LastName', 'Putin');
// Get the parameters
const p = status.parameters; // returns ["LastName", "Putin"]

// In the above, the message placeholders %1 and %2 will be replaced by "LastName" and "Putin".
// So the final message may be "Field with name 'LastName' contains illegal value 'Putin'."

subStatus​

subStatus: Status[]

Returns an array of States which are sub states to the current Status. Same as getSubStatus.

Example​

// Get array of States.
const statusArray = status.subStatus;

vendor​

vendor: Vendor

The vendor of the Status. See also Status.getVendor. Same as getVendor.

Example​

// Create a new Status
const status = Status.create(VENDOR, 'ILLEGAL_VALUE', 'LastName', 'Putin');
// Get the vendor
const v = status.vendor; // returns VENDOR

vendorId​

vendorId: number

The ID of the Vendor which is associated with this Status. Same as getVendorId.

Example​

// Create a new Status
const status = Status.create(VENDOR, 'ILLEGAL_VALUE', 'LastName', 'Putin');
// Get the vendor
const vId = status.vendorId; // returns 42

Methods​

getCode()​

getCode(): string

Returns the code of a Status.

Returns​

string

  • Status code

Example​

// Get the status code
const code = status.getCode();
// Result: 4711

getMessage()​

getMessage(): string

Returns the uncompiled message of a Status. If it includes placeholders, these will not be filled. Sames as message.

Returns​

string

  • Status message

Example​

// Get the status message. Placeholders defined in a Status are not replaced with parameters, if any.
const message = status.getMessage();
// Result: "The name is %1, %2."

getParameters()​

getParameters(): string[]

Returns an array of parameters which may have been passed to the Status upon creation. See: create. Same as parameters.

Returns​

string[]

  • Array of Status parameters which were passed when Status was created.

Example​

// Get array of parameters.
const paramArray = status.getParameters();
// Result: ["Doe", "John"]

getSubStatus()​

getSubStatus(): Status[]

Returns an array of States which are sub states to the current Status.

Returns​

Status[]

  • Array of States which are sub states to the current Status.

Example​

// Get array of States.
const statusArray = status.getSubStatus();

getVendor()​

getVendor(): Vendor

Returns the vendor of a Status. Same as vendor.

Returns​

Vendor

  • VendorInfo structure.

Example​

// Get array of parameters.
const VENDOR_INFO = status.getVendor();

getVendorId()​

getVendorId(): number

Returns the ID of the vendor of a Status. Same as vendorId.

Returns​

number

  • ID of the vendor of a Status.

Example​

// Get the vendor ID
const vendorId = status.getVendorId();
// Result: 42

create()​

static create(vendor, statusCode, ...args): Status

Invoke to create a Status.

Parameters​

• vendor: Vendor

Status messages can be distinguished by vendor. Pass a VendorInfo here. Obtain it with Status.getVendorByName

• statusCode: string

The statusCode which must be defined within your "Resource Status Definition Asset" of your Project. This code will be used to identify the Status which you want to add.

• ...args: string[]

A comma separated list of arguments which will be used to fill in the placeholders in the predefined Status message, if any

Returns​

Status

Instance of newly created Status.

Example​

// Assume we have - among others - the following status defined using a "**Resource Status Definition Asset**":
// Logical name: "ILLEGAL_VALUE"
// Message: "Field with name '%1' contains illegal value '%2'."

// Get the vendor instance from the list of defined vendors.
// You must have defined the vendor in a "**Resource Status Definition Asset**".
// The string passed in `Status.getVendorByName('myVendorLongName')`
// is the long name of the Vendor definition within that Asset.
// Check documentation for "**Resource Status Definition Asset**" for more info.
const VENDOR = Status.getVendorByName('MyVendorLongName');

// Create the Status
const STATUS = Status.create(
     VENDOR,
     'ILLEGAL_VALUE',
     'LastName',
