Issue in nested stl maps

Hello,
In the following code, I am trying to to sPolicyRule to cIpAddressPolicyRulesInfo which gets added..But somehow the outer class(or map) doesnot get updated i.e the class CPCRF::m_mIMSI2ApnPolicyRuleInfo

Code:

---

map<string, APN2PolicyRules>::iterator iTer = CPCRF::m_mIMSI2ApnPolicyRuleInfo.find(sImsi);

                                                                                APN2PolicyRules cApn2PolicyRulesInfo = iTer->second;

                                                                                APN2PolicyRules::iterator iTerApn = cApn2PolicyRulesInfo.find(sApn);

                                                                                IPAddressPolicyRulesInfo cIpAddressPolicyRulesInfo = iTerApn->second;

                                                                                PolicyRuleInfo sPolicyRule(stQoSInfo, stTFT);

                                                                                cIpAddressPolicyRulesInfo.addPolicycyRule(sDedicatedBearerId, sPolicyRule);

Iam in hurry so any help clues are much appreciated.

When i gdb policyRules has two map elements, but the main class has only one..

(gdb) p cIpAddressPolicyRulesInfo

thanks a lot in advance for the help

Please format you code to make it readable.

Code:

---

APN2PolicyRules cApn2PolicyRulesInfo = iTer->second;

---

This creates a copy. The copy is not in the map, so anything you do with the copy will not affect the elements in the map.
If you want to update the element in the map, use a reference instead of making a copy.

Thanks a lot Drmmr for the quick reply. I also was checking this and found this, and now tested with fix it is working.. :)
