Accessors

isReady

get isReady(): boolean
Returns boolean
- Defined in Source/Core/Audio/Audio.ts:27

isSerializableResource

get isSerializableResource(): true
Returns true
Implementation of SerializableResource.isSerializableResource
- Defined in Source/Core/Audio/Audio.ts:23

type

get type(): string
Retrieves the type of this mutable subclass as the name of the runtime class

Returns string
The type of the mutable
Implementation of SerializableResource.type
Inherited from Mutable.type
- Defined in Source/Core/Serialization/Mutable.ts:193

Methods

addEventListener

addEventListener(
    _type: string,
    _handler: EventListenerUnified,
    _options?: boolean | AddEventListenerOptions,
): void
See EventTarget.addEventListener for reference. Works with EventListenerUnified and EventUnified
Parameters
- _type: string
- _handler: EventListenerUnified
- Optional_options: boolean | AddEventListenerOptions
Returns void
Inherited from Mutable.addEventListener
- Defined in Source/Core/Event/Event.ts:91

animate

animate(_mutator: AnimationMutator): void
Updates the property values of the instance according to the state of the animation mutator. Override to implement custom animation behavior.
Parameters
- _mutator: AnimationMutator
Returns void
Inherited from Mutable.animate
- Defined in Source/Core/Serialization/Mutable.ts:329

deserialize

deserialize(_serialization: Serialization): Promise<Serializable>
Recreates this instance of Serializable with the information from the given Serialization.
Parameters
- _serialization: Serialization
Returns Promise<Serializable>
Implementation of SerializableResource.deserialize
- Defined in Source/Core/Audio/Audio.ts:56

dispatchEvent

dispatchEvent(_event: EventUnified): boolean
See EventTarget.dispatchEvent for reference. Works with with EventUnified
Parameters
- _event: EventUnified
Returns boolean
Inherited from Mutable.dispatchEvent
- Defined in Source/Core/Event/Event.ts:105

getMetaAttributeTypes

getMetaAttributeTypes(): MetaAttributeTypes
Retrieves the specified attribute types from the metadata of this instance's class.

Returns MetaAttributeTypes
Inherited from Mutable.getMetaAttributeTypes
- Defined in Source/Core/Serialization/Mutable.ts:289

getMetadata

getMetadata(): Metadata
Retrieves the metadata of this instance's class.

Returns Metadata
Inherited from Mutable.getMetadata
- Defined in Source/Core/Serialization/Mutable.ts:296

getMutator

getMutator(_extendable?: boolean): Mutator
Collect applicable attributes of the instance and copies of their values in a Mutator-object. By default, a mutator cannot be extended, since extensions are not available in the object the mutator belongs to. A mutator may be reduced by the descendants of Mutable to contain only the properties needed.
Parameters
- _extendable: boolean = false
Returns Mutator
Inherited from Mutable.getMutator
- Defined in Source/Core/Serialization/Mutable.ts:202

getMutatorAttributeTypes

getMutatorAttributeTypes(_mutator: Mutator): MutatorAttributeTypes
Returns an associative array with the same attributes as the given mutator, but with the corresponding types as string-values. Does not recurse into objects! This will return the decorated meta-type instead of the runtime-type of the object, if available.
Parameters
- _mutator: Mutator
Returns MutatorAttributeTypes
Inherited from Mutable.getMutatorAttributeTypes
- Defined in Source/Core/Serialization/Mutable.ts:260

getMutatorForAnimation

getMutatorForAnimation(_extendable?: boolean): MutatorForAnimation
Collect the attributes of the instance and their values applicable for animation. Basic functionality is identical to getMutator, returned mutator should then be reduced by the subclassed instance
Parameters
- _extendable: boolean = false
Returns MutatorForAnimation
Inherited from Mutable.getMutatorForAnimation
- Defined in Source/Core/Serialization/Mutable.ts:237

getMutatorForUserInterface

getMutatorForUserInterface(_extendable?: boolean): MutatorForUserInterface
Collect the attributes of the instance and their values applicable for the user interface. Basic functionality is identical to getMutator, returned mutator should then be reduced by the subclassed instance
Parameters
- _extendable: boolean = false
Returns MutatorForUserInterface
Inherited from Mutable.getMutatorForUserInterface
- Defined in Source/Core/Serialization/Mutable.ts:245

load

load(_url: RequestInfo): Promise<void>
Asynchronously loads the audio (mp3) from the given url
Parameters
- _url: RequestInfo
Returns Promise<void>
- Defined in Source/Core/Audio/Audio.ts:34

mutate

mutate(
    _mutator: Mutator,
    _selection?: string[],
    _dispatchMutate?: boolean,
): Promise<void>
Updates the attribute values of the instance according to the state of the mutator. The mutation may be restricted to a subset of the mutator and the event dispatching suppressed. Uses mutateBase, but can be overwritten in subclasses
Parameters
- _mutator: Mutator
- Optional_selection: string[]
- Optional_dispatchMutate: boolean
Returns Promise<void>
Overrides Mutable.mutate
- Defined in Source/Core/Audio/Audio.ts:63

removeEventListener

removeEventListener(
    _type: string,
    _handler: EventListenerUnified,
    _options?: boolean | AddEventListenerOptions,
): void
See EventTarget.removeEventListener for reference. Works with EventListenerUnified and EventUnified
Parameters
- _type: string
- _handler: EventListenerUnified
- Optional_options: boolean | AddEventListenerOptions
Returns void
Inherited from Mutable.removeEventListener
- Defined in Source/Core/Event/Event.ts:98

serialize

serialize(): Serialization
Returns a Serialization of this object.

Returns Serialization
Implementation of SerializableResource.serialize
- Defined in Source/Core/Audio/Audio.ts:48

updateMutator

updateMutator(_mutator: Mutator): void
Updates the values of the given mutator according to the current state of the instance
Parameters
- _mutator: Mutator
Returns void
Inherited from Mutable.updateMutator
- Defined in Source/Core/Serialization/Mutable.ts:304

`Static`getMutatorFromPath

getMutatorFromPath(_mutator: Mutator, _path: string[]): Mutator
Decorator allows to attach Mutable functionality to existing classes.
Parameters
- _mutator: Mutator
- _path: string[]
Returns Mutator
Inherited from Mutable.getMutatorFromPath
- Defined in Source/Core/Serialization/Mutable.ts:178
