# requiredProtocols

`open val requiredProtocols: Map<String, Set<String>>`

A Map with an entry for each consumed protocol used by the webAPIs. The key of each map entry should contain the ProtocolLogic class name. The associated map values are the union of all concrete class names passed to the protocol constructor. Standard java.lang.* and kotlin.* types do not need to be included explicitly. This is used to extend the white listed protocols that can be initiated from the ServiceHub invokeProtocolAsync method.
