Interface MIDIOutputMap

The MIDIOutputMap read-only interface of the Web MIDI API provides the set of MIDI output ports that are currently available. Available only in secure contexts.

interface MIDIOutputMap {
    size: number;
    "[iterator]"(): MapIterator<[string, MIDIOutput]>;
    entries(): MapIterator<[string, MIDIOutput]>;
    forEach(
        callbackfn: (
            value: MIDIOutput,
            key: string,
            parent: MIDIOutputMap,
        ) => void,
        thisArg?: any,
    ): void;
    get(key: string): MIDIOutput | undefined;
    has(key: string): boolean;
    keys(): MapIterator<string>;
    values(): MapIterator<MIDIOutput>;
}
