cmakepp_lang/class/detail/bases._cpp_class_get_bases(this bases)

Note

This is a macro, and so does not introduce a new scope.

Encapsulates the logic for retrieving the base classes of a user-defined type.

The type system needs to know which base classes a user-defined class can be implicitly converted to. This function encapsulates the logic of retrieving that list to avoid a direct coupling to how that list is stored.

Note

This function is used by cpp_implicitly_convertible and thus is inside the type-checking machinery which can not have its type checked by cpp_assert_signature. Also worth noting this function is currently a macro because all it does is set a variable for the caller, thus we save a call to cpp_return.

Parameters:

this (class) – The class instance we are retrieving the bases of.
bases – An identifier to which the list of base classes will be assigned.
bases – desc

Returns:

bases will be set to the list of base classes that the user-defined type stored in this derives from. This is not the list of base classes that the Class class derives from.

Return type:

[type]

Error Checking

This function will ensure that it has been called with exactly two arguments, and if it has not, will raise an error.

cmakepp_lang/class/detail/bases._cpp_class_set_bases(this bases)

Encapsulates the logic for setting the base classes of a user-defined: type.

The type system needs to know which base classes a user-defined class can be implicitly converted to. This function encapsulates the logic of setting that list to avoid a direct coupling to how that list is stored. If the bases for a class have already been set this function will overwrite the previous list.

Parameters:

this (class) – The class instance we are setting the bases of.
bases – An identifier containing the list of base classes.
bases – [type]*

Variables:

CMAKEPP_LANG_DEBUG_MODE (bool) – Used to determine if CMakePP is being run in debug mode or not.

Error Checking

If CMakePP is run in debug mode (and only when it is) this function will assert that the caller supplied exactly two arguments and that those arguments have the correct types.
