set
Updates the state object of a feature within a style source.
Update entries in the state object of a given feature within a style source. Only properties of the state object will be updated. A property in the feature state object that is not listed in state will retain its previous value. The properties must be paint properties, layout properties are not supported.
Note that updates to feature state are asynchronous, so changes made by this method might not be immediately visible using getStateFeature. And the corresponding source needs to be in use to ensure the feature data it contains can be successfully updated.
Return
A cancelable object that could be used to cancel the pending operation.
Parameters
The style source identifier.
The style source layer identifier (for multi-layer sources such as vector sources).
The feature identifier of the feature whose state should be updated.
The state object with properties to update with their respective new values.
The feature state operation callback called when the operation completes or ends.
