Types

type ARMResourceModifier 

type ARMResourceModifier interface {
	// ModifyARMResource takes a genruntime.ARMResource and returns an updated genruntime.ARMResource. The updated resource
	// is then serialized and sent to ARM in the body of a PUT request.
	ModifyARMResource(
		ctx context.Context,
		armClient *genericarmclient.GenericClient,
		armObj genruntime.ARMResource,
		obj genruntime.ARMMetaObject,
