Howdy Foamers:

I am scratching my head on this. I am using a DynamicList in my solver implementation. According to the OpenFOAM API, DynamicList is inherited from List, which is in turn inherited from UList.

List has a public member append(), while UList has a public member find(). In theory both should be accessible from my instance of DynamicList.

However, while calling DynamicList::append() compiled without problem, the compiler complained about DynamicList not being to access find(). This behavior is consistent with all member functions in List (no errors) and UList (compiler errors). This leads me to believe this could be an issue with my understanding with the C++ language.

I am wondering if I am missing something, and how could I access the find function from DynamicList?

Thanks in advance, Gerry.

A few notes, kinda strange:

1) find () is not in UList in the distribution I am using (OF 7), while it is according to the 2006 API. Strange, but I guess my assumption is wrong, where the implementation for the very basic classes are supposedly identical between .org and .com.

2) Looks like you do need to refer to the base class when calling one of its member functions, i.e., myDynamicList.UList::find(), assuming the member find() is here.

Okay, i ended up implementing the find member function in the .org flavor of UList. I am still scratching my head as to why the basic data structure are differently implemented.

FOAM was conceived in a time where STL wasnt as mature, so many basic containers were implemented directly as to avoid library performance issues. An example is the autoPtr<> handle, which in some forks of FOAM is beibg slowly converted to std::auto_ptr.
