unmarshalJson

public static <T extends VersionedData> T unmarshalJson(VersionedDataKind<T> kind,

Unmarshals a feature store item from a JSON string. This is a very simple wrapper around a Gson method, just to allow external feature store implementations to make use of the Gson instance that's inside the SDK rather than having to import Gson themselves.

Type Parameters:

T - class of the object that will be returned

Parameters:

kind - specifies the type of item being decoded

data - the JSON string

Returns:

the unmarshaled item

Throws:

FeatureStoreHelpers.UnmarshalException - if the JSON string was invalid

the JSON string
