IFluidParentContext Interface

Represents the context for the data store like objects. It is used by the data store runtime to get information and call functionality to its parent.

This layout is temporary, as IFluidParentContext and IFluidDataStoreContext will converge.

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

To use, import via @fluidframework/runtime-definitions/legacy.

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