Detailed Description

weak reference to ZFObject

usage:

ZFArray *obj = xxx;
 
zfweak p1 = obj;
ZFArray *access1 = p1.get();
 
zfweakT<ZFArray> p2 = obj;
if(p2) {
    p2.get()->add(xxx);
}
p2.set(xxx);
if(p2.valid()) {
    p2.get()->add(xxx);
}

can be used in script with similar rule, lua for example:

local a = ZFArray();
 
local p1 = zfweak(a);
local access1 = p1:get();
 
local p2 = zfweak(a);
if(p2:get() ~= zfnull) {
    p2:get():add(xxx);
}
p2:set(xxx);
if(p2:valid()) {
    p2:get():add(xxx);
}
