provideDataAndAdvance

protected void provideDataAndAdvance(DataSourceRole role,
                                     Consumer<IndirectionDate> continuation)

Description copied from class: AbstractSimDataChannelResource

It must hold that #provideDataAndAdvance(DataChannelSourceConnector) can be called iff #canProvideData(DataChannelSourceConnector) was true immediately before the call.

Calling #provideDataAndAdvance(DataChannelSourceConnector) in a loop must eventually lead to #canProvideData(DataChannelSourceConnector) returning false.
