- rename LIBCMO_DISABLE_COPY_MOVE -> YYCC_DEL_CLS_COPY_MOVE and LIBCMO_DEFAULT_COPY_MOVE -> YYCC_DEF_CLS_COPY_MOVE. - fix Vector declaration generator. throw exception when operator[] face invalid index, instead of do fallback. - rename VTAll.hpp -> VTInternal.hpp and VYUserAll -> VTAll.hpp for easy to understand. - fix project name error in Doxygen template. - replace all LIBCMO_OS_WIN32 to YYCC_OS == YYCC_OS_WINDOWS. - fix some compile error (involving utf8 encoding) but not the final result. - use correct way to include std-image library (use <> instead of "") - finish documentation for VTUtils.hpp and VTEncoding.hpp.

|
|
A small hint for ToBeNotify, CommonToBeNotify and ToNotify
|
|
Assume that A need notification from B, we can see it as that A want buy something from B.
|
|
This relation is represented in ToBeNotify, a pure relation without any inhertance hierarchy.
|
|
|
|
Ok, now we assume A have children AA, B also have children BB.
|
|
Because B is a businessman, so his children BB also is a bussinessman.
|
|
B and BB have the same goods so A can buy his stuff from both of B and BB.
|
|
This is the first step executed by ComputeParentsNotifyTable().
|
|
In this step, the function expand existing business relations to all possible business relations (expand to businessman's children)
|
|
|
|
Image there is a candy store, C. Because AA still is a kids.
|
|
So AA want to buy something from C. Now C is in his ToBeNotify.
|
|
Additionally, A, the parent of AA, force AA to buy something from B, just for A himself.
|
|
For AA, he does not need want to buy something from B, but his parent A order he to do.
|
|
This is the second step executed by ComputeParentsNotifyTable().
|
|
For AA, his parent's relations also need to be merged after he processed his relations with C like I introduced previously.
|
|
|
|
Now, AA have a full business list writing all trades he can do.
|
|
This is represented as CommonToBeNotify.
|
|
In this time, AA's ToBeNotify only have C, but his CommonToBeNotify have B, BB and C.
|
|
|
|
So now, let we change the view from A to B.
|
|
B want to know whom I can sell something to.
|
|
Because a full trades list are created from A side.
|
|
The better solution is just ask the guest: do you want to buy something from me?
|
|
This operation will fill ToNotify and is implemented at ComputeHierarchyTable().
|
|
|
|
At the end of this story,
|
|
All bussiness man can use ToNofity to see whom they want to sell something to.
|
|
And all buyer can use CommonToBeNofity to check who they can buy something from.
|
|
ToBeNotify is just a list to indicate the initial bussiness relation and will never used anymore after real relation established.
