PureDataObjectFactory Class

PureDataObjectFactory is a bare-bones IFluidDataStoreFactory for use with PureDataObject. Consumers should typically use DataObjectFactory instead unless creating another base data store factory.

This API is provided for existing users, but is not recommended for new users.

To use, import via @fluidframework/aqueduct/legacy.

For more information about our API support guarantees, see here.

Signature

export declare class PureDataObjectFactory<TObj extends PureDataObject<I>, I extends DataObjectTypes = DataObjectTypes> implements IFluidDataStoreFactory, Partial<IProvideFluidDataStoreRegistry>

Implements: IFluidDataStoreFactory, Partial<IProvideFluidDataStoreRegistry>

Type Parameters

Parameter	Constraint	Default	Description
TObj	PureDataObject<I>		DataObject (concrete type)
I	DataObjectTypes	DataObjectTypes	The input types for the DataObject

Constructors

Constructor	Alerts	Description
(constructor)(type, ctor, sharedObjects, optionalProviders, registryEntries, runtimeClass)	Beta	Constructs a new instance of the PureDataObjectFactory class
(constructor)(props)	Beta	Constructs a new instance of the PureDataObjectFactory class

Properties

Property	Alerts	Modifiers	Type	Description
IFluidDataStoreFactory	Beta	readonly	this
IFluidDataStoreRegistry	Beta	readonly	IFluidDataStoreRegistry | undefined
registryEntry	Beta	readonly	NamedFluidDataStoreRegistryEntry	Convenience helper to get the data store's/factory's data store registry entry. The return type hides the factory's generics, easing grouping of registry entries that differ only in this way into the same array.
type	Beta	readonly	string

Methods

Method	Alerts	Return Type	Description
createChildInstance(parentContext, initialState, loadingGroupId)	Beta	Promise<TObj>	Creates a new instance of the object. Uses parent context's registry to build package path to this factory. In other words, registry of context passed in has to contain this factory, with the name that matches this factory's type. It is intended to be used by data store objects that create sub-objects.
createInstance(runtime, initialState, loadingGroupId)	Beta	Promise<TObj>	Creates a new instance of the object. Uses container's registry to find this factory. It's expected that only container owners would use this functionality, as only such developers have knowledge of entries in container registry. The name in this registry for such record should match type of this factory.
createInstanceCore(context, initialState)	Beta	Promise<TObj>
createInstanceWithDataStore(containerRuntime, initialState, packagePath, loadingGroupId)	Beta	Promise<[TObj, IDataStore]>	Creates a new instance of the object with a datastore which exposes the aliasing api.
createNonRootInstanceCore(containerRuntime, packagePath, initialState, loadingGroupId)	Beta	Promise<TObj>
createPeerInstance(peerContext, initialState, loadingGroupId)	Beta	Promise<TObj>	Creates a new instance of the object. Uses peer context's registry and its package path to identify this factory. In other words, registry of context passed in has to have this factory. Intended to be used by data store objects that need to create peers (similar) instances of existing objects.
createRootInstance(rootDataStoreId, runtime, initialState)	Deprecated, Beta	Promise<TObj>	Creates a new root instance of the object. Uses container's registry to find this factory. It's expected that only container owners would use this functionality, as only such developers have knowledge of entries in container registry. The name in this registry for such record should match type of this factory.
instantiateDataStore(context, existing)	Beta	Promise<IFluidDataStoreChannel>

Method Details

createChildInstance

Creates a new instance of the object. Uses parent context's registry to build package path to this factory. In other words, registry of context passed in has to contain this factory, with the name that matches this factory's type. It is intended to be used by data store objects that create sub-objects.

This API is provided for existing users, but is not recommended for new users.

For more information about our API support guarantees, see here.

Signature

createChildInstance(parentContext: IFluidDataStoreContext, initialState?: I["InitialState"], loadingGroupId?: string): Promise<TObj>;

Parameters

Parameter	Modifiers	Type	Description
parentContext		IFluidDataStoreContext
initialState	optional	I["InitialState"]	The initial state to provide to the created data store.
loadingGroupId	optional	string	NOT production ready, EXPERIMENTAL, please read README. The service needs to support this feature, does not work for most services

Returns

an object created by this factory. Data store and objects created are not attached to container. They get attached only when a handle to one of them is attached to already attached objects.

Return type: Promise<TObj>

createInstance

Creates a new instance of the object. Uses container's registry to find this factory. It's expected that only container owners would use this functionality, as only such developers have knowledge of entries in container registry. The name in this registry for such record should match type of this factory.

Parameters

Parameter	Modifiers	Type	Description
runtime		IContainerRuntimeBase	container runtime. It's registry is used to create an object.
initialState	optional	I["InitialState"]	The initial state to provide to the created component.
loadingGroupId	optional	string	NOT production ready, EXPERIMENTAL, please read README. The service needs to support this feature, does not work for most services

Returns

an object created by this factory. Data store and objects created are not attached to container. They get attached only when a handle to one of them is attached to already attached objects.

It's expected that only container owners would use this functionality, as only such developers have knowledge of entries in container registry. The name in this registry for such record should match type of this factory.

This API is deprecated and will be removed in a future release.

• the issue is that it does not allow the customer to decide the conflict resolution policy when an aliasing conflict occurs. Use createInstanceWithDataStore(containerRuntime, initialState, packagePath, loadingGroupId) instead.
