                                                         java.util.function.Function<X,​T> conversion)
        Deprecated.
        Creates a StreamId that will be used to create a Publisher which will emit items based on a Publisher identified by the provided StreamId. The conversion function always returns an Optional, if the value is present then it will be emitted, otherwise nothing will be emitted.
        Parameters:
        sourceStreamId - StreamId which identifies a Publisher that will be used as the source of the converted objects.
        conversion - Function used to convert the objects.
        Returns:
        A StreamId.
        Throws:
        java.lang.NullPointerException - If the provided source stream id or conversion function are null.

        Deprecated.
        EXPERIMENTAL Creates a StreamId that will identify a Publisher which will emit items based on a Publisher identified by the provided StreamId. The conversion function always returns a Publisher which will used as the source of the objects to be flattened, if the stream emits values then these will be emitted, otherwise nothing will be emitted.
        Parameters:
        sourceStreamId - StreamId which identifies the Publisher that will be used as the source of the converted objects.
        conversion - Function used to convert the objects.
        Returns:
        A StreamId.
        Throws:
        java.lang.NullPointerException - If the provided source stream id or conversion function are null.

        Deprecated.
        EXPERIMENTAL Creates a StreamId that will be used to create a Publisher which will emit all the items emitted by the Publishers identified by the provided StreamIds.
        Parameters:
        sourceStreamIds - List of StreamIds which identify Publishers that will be used as the source of the new Publisher.
