Class charts

the main namespace of all javascript stock3 AG javascript libraries.

includes the chartbreaker library in BG.charts as well as dependencies like BG.events.EventEmitter, BG.locale, and BG.clazz the main namespace of the ChartBreaker library

includes all classes of ChartBreaker distributed over several sub namespaces some global events are available directly on the namespace object itself

Parameters
- type: Type
- listener: Callback
Returns this
Description

setMaxListeners

setMaxListeners(maxListeners: number): this
Parameters
- maxListeners: number
Returns this
Description
by default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default which helps finding memory leaks. Obviously not all Emitters should be limited to 10. This function allows that limit to be increased. Set to zero for unlimited.

`Static`guard

guard(cb: Function): void
Parameters
- cb: Function
Returns void
Description
set custom error handler for event listeners

Inherited from EventEmitter.guard

`Static`listenerCount

listenerCount<
    EvType extends BG.events.Events,
    Type extends string | number | symbol,
>(
    emitter: EventEmitter<EvType>,
    type: Type,
): number
Type Parameters
- EvType extends BG.events.Events
- Type extends string | number | symbol
Parameters
- emitter: EventEmitter<EvType>
- type: Type
Returns number
Description
returns number of listeners on specified emitter for specified type

Inherited from EventEmitter.listenerCount

`Static`setDefaultMaxListeners

setDefaultMaxListeners(maxListeners: number): void
Parameters
- maxListeners: number
Returns void
Description
set default amount for limit warning
