Remarks

This method provides an interface to the internal negotiation algorithm. You may use it to check whether your ACL provides expected results.

The following is a pseudo code of how this method is implemented:

Copy
if(InThreadID == 0)
    InThreadID = GetCurrentThreadId();

if(GlobalACL.Contains(InThreadID))
{
    if(LocalACL.Contains(InThreadID))
    {
        if(LocalACL.IsExclusive)
            return false;
    }
    else
    {
        if(GlobalACL.IsExclusive)
            return false;

        if(!LocalACL.IsExclusive)
            return false;
    }
}
else
{
    if(LocalACL.Contains(InThreadID))
    {
        if(LocalACL.IsExclusive)
            return false;
    }
    else
    {
        if(!GlobalACL.IsExclusive)
            return false;

        if(!LocalACL.IsExclusive)
            return false;
    }
}

return true;
