Add basic Adapter generation

Add basic generation of a Adapter .cpp and .h files

Deliverables:

• new Template Adapter.cpp.ftl and/or Adapter.h.ftl

  • Can be based on Adapter.ftl template in EMAM2Roscpp. Possible easiest if you implement your own MQTTMacro.ftl(reference: RosMacros.ftl) and use the original Adapter.ftl.
  • Result should look or work similar to your example adapter .cpp and .h
  • Assume all values are written/read as doubles for now(e.g. ignore all Matrix/Vector types, Struct Types)
  • You can ignore all generics, for now
  • The resulting class should should be named MQTTAdapter_${escapedCompName}, where ${escapedCompName} is componentInstance.getFullName() with all ., [,] replaced by _

• In MQTTTemplates:

  • A new constant + fill method pair for the new template(s)

• A new Class MQTTAdapterModel:

  • can be based on the RosAdapterModel in RosCpp
  • should contain all information needed to generate the Adapter
    • (escaped) name of the component instance
    • MQTTPorts of the component
      • Possibly grouped by incomming/outgoing(for subscribers/publishers respectivly)

• In MQTTGenerator:

  • a method + List<File> generateAdapter(EMAComponentInstanceSymbol) that generates the CMake file using the MQTTTemplate Class and the template Adapter.cpp.ftl and/or Adapter.h.ftl.

• Add a test case:

  • as previously(Issue #13 (closed)):
    • parse a simple componentInstance
    • manually add MQTTConnectionSymbols with EMAPortInstanceSymbol::setMiddlewareSymbol
  • call generateCMake on the componentInstance
  • compare the resulting File(s) with an expected result(AbstractSymtabTest::testFilesAreEqual)
