Some examples using the ArduinoSTL library.

The file newhandler.cpp has been patched to avoid the double definition of no_throw.

I have also patched new.cpp as well for the Arduino 1.5.1 ArduinoBoostFunction example.

Basic example compiles O.K. on a UNO

Example of the Composite Pattern which is now working. Compiles O.K. on a UNO

Example of the Composite Pattern with the composite classes in a header.

Using list instead of vector for the children.

The code has been changed to use a different example from refactoring.guru.

This supports holding parent information (on one parent).

I have retained the support of named items and added GetName to return the information.

This extends the previous example to allow for multiple parents.

I have now used this as a starting point for SignalComposite.

Implementation of the Observer Pattern from previous code.

I want to explore combining Observer and Composite.

I am exploring another simpler implementation of the Observer Pattern.

The example source is not complete code and there are also alternative suggestions.

This compiles without a working example.

Alternative suggestions.

It is not possible to implement some features of this proposal on the ArduinoSTL system.

There are several ways to approach this.

1. Attempt to work around within this proposal e.g use Boost function instead of std::function. I have tried this. There are problems with both of the Boost versions I have.
2. Merge the two ways together avoiding the features which are not supported.
3. Move this idea to another system e.g. Raspberry Pi PICO.

Attempt to work with Boost. This has failed as I cannot sort out the clashes between libraries.

I am going instead to work around things for the ARM boards. This is looking more promising.

I now have this working. For some reason it runs more than once from compilation.

This version has the Observer code moved to a header file.
