Requires IsKeyedObjectContainer in TupleTree.h wherever possible,
instead of IsContainer. This enables using std::vectors.
In this way, they will not be diffed based on the key, but on the entire
vector. This is intended.
Add a specialization for
CallByPathVisitorWithInstance::visitContainerElement to handle cases
where the element of the container is an UpcastablePointer, that needs
to be unwrapped before visiting.
This fixes a problem causing bad TupleTree traversal with
TupleTreeReference. Specifically, CallByPathVisitorWithInstance did not
know how to visitContainerElement when the element of the container was
an UpcastablePointer. This caused the visit to always return nullptr
even when the TupleTreeReference was well-formed. This has been fixed by
adding an overload with proper concept constraint, that teaches
CallByPathVisitorWithInstance how to properly traverse
UpcastablePointers.
This commit drops the KeyTraits in favor of a std::any-like solution.
Basically, we type erase any key the user wants to employ, just exposing
a virtual version of the destructor, a comparison operator and a clone
primitive.
This commit:
* Drops `KeyTraits::toString`: if needed, use `getNameFromYAMLScalar`.
* Makes many methods in TupleTree.h return `nullptr` or `std::optional`
in order to gracefully handle failures.
* Provides `KeyTraits` specializations for integral types and tuple-like
composed by types providing `KeyTraits`.
* Introduces `CompositeScalar`, which enables tuple-like objects to be
YAML-serializable scalars by joining the YAML-serialization of its
members through a customziable character.
* Implements `PathMatcher`, a very simple "regular expression" mechanism
for paths on tuple trees.
* Introduce testing for the Model.
This commit extends the support for the FOR_EACH macro used in
INTROSPECTION_NS to allow serialization of structs with more than
5 entries. Now it supports up to 16 entries.
