API

taggedString(chaines: string, ...keys: any[]): Clojure

This method is inspired from Tagged Literal (look at the MDN Documentation)

Useful to build string templates:

const{ strictEqual }=require("assert");consttpl=taggedString`hello ${0}`;strictEqual(tpl("fraxken"),"hello fraxken");

Template properties can be either index or key:

const{ strictEqual }=require("assert");consttpl=taggedString`hello ${"name"}`;strictEqual(tpl({name: "fraxken"}),"hello fraxken");

createDirectory(path: string): void

Create a directory at the given path. This method trigger fs.mkdir but catch the ENOENT error if the directory exist.

assertEntity(entity: SlimIO.RawEntity): void

Assert an Entity Object.

assertEntity({name: "myEntity",description: "desc",parent: 10,descriptors: {}});

assertMIC(mic: SlimIO.RawIdentityCard): void

Assert an MicIdentityCard Object.

assertMIC({name: "myMIC",entityId: 1,unit: "unit",interval: 10,max: 100,description: "desc"});

assertAlarm(alarm: SlimIO.RawAlarm): void

Assert an Alarm Object.

assertAlarm({message: "message",severity: 1,entityId: 2,correlateKey: "test_corrKey"});

assertCorrelateID(CID: SlimIO.CID): void

Assert a correlate id (Alarm correlate id). A CID is the addition of a Alarm ID and a Correlate key. The maximum length of the CID is 44.

assertCorrelateID("1#test_corrkey");

assertCK(correlateKey: string): void

Assert a correlate key (Alarm correlate key). The length of CK must be between 1 and 35.

assertCK("test_corrkey");

privateProperty(target: object, propertyKey: string|symbol|number, value?: any): void

Define a private (non-enumable, non-configurable) property on the target.

constassert=require("assert");constobj={};privateProperty(obj,"foo","bar");assert.deepEqual(Object.keys(obj),[]);obj.foo="world!";assert.strictEqual(obj.foo,"world!");assert.throws(()=>{deleteobj.foo;},{name: 'TypeError'});
