Corba-style interfaces can use any string as ID so for local interfaces it is
possible to use shorter ID-strings for better performance.
MSEide constructs such ID's by RightClick-'Insert UID'. Example: "['jA']{49}".
If the interface is listed in header of the queried class it is also possible
to get the interface by compile time type conversion:
"
type
{$interfaces corba}
iabc = interface
procedure a();
procedure b();
procedure c();
end;
tabc = class(tobject,iabc)
protected
procedure a();
procedure b();
procedure c();
end;
var
abc: tabc;
abcintf: iabc;
[...]
abcintf:= iabc(abc);
"
which has the best performace.
