utils/events¶

Classes¶

EventEmitter¶

Defined in: utils/events.ts:8

Minimal typed pub/sub used by StateManager and ConnectionStatusService. Listeners are invoked synchronously; exceptions are caught so one bad listener cannot break others (same semantics as the prior hand-rolled implementations).

Type Parameters¶

T¶

T

Constructors¶

Constructor¶

new EventEmitter<T>(logContext?): EventEmitter<T>;

Defined in: utils/events.ts:11

Parameters¶

logContext?¶

string = 'EventEmitter'

Returns¶

EventEmitter\<T>

Accessors¶

size¶

Get Signature¶

get size(): number;

Defined in: utils/events.ts:34

Returns¶

number

Methods¶

subscribe()¶

subscribe(listener): () => void;

Defined in: utils/events.ts:13

Parameters¶

listener¶

(data) => void

Returns¶

() => void

emit()¶

emit(data): void;

Defined in: utils/events.ts:20

Parameters¶

data¶

T

Returns¶

void

clear()¶

clear(): void;

Defined in: utils/events.ts:30

Returns¶

void

ListenerRegistry¶

Defined in: utils/events.ts:43

Tracks addEventListener registrations so they can be torn down in one call. Replaces the identical hand-rolled arrays in BasePanel and Header.

Constructors¶

Constructor¶

new ListenerRegistry(): ListenerRegistry;

Returns¶

ListenerRegistry

Accessors¶

size¶

Get Signature¶

get size(): number;

Defined in: utils/events.ts:68

number

Methods¶

add()¶

add(
   element, 
   event, 
   handler, 
   options?): void;

Defined in: utils/events.ts:51

Parameters¶

element¶

EventTarget

event¶

string

handler¶

EventListenerOrEventListenerObject

options?¶

boolean | AddEventListenerOptions

Returns¶

void

removeAll()¶

removeAll(): void;

Defined in: utils/events.ts:61

Returns¶

void
