c++ stl map

[pdk5]

Hello
I have the following map :

listOfPolicyRuleInfo CPCRF::m_mlistOfCliConfiguredPolicyRules;

where typedef map<string, PolicyRuleInfo> listOfPolicyRuleInfo;

where PolicyRuleInfo is a struct

struct PolicyRuleInfo{
BearerQoSInfo stBearerQoS;
TFTInfo stTFTInfo;
PolicyRuleInfo(){};
PolicyRuleInfo( BearerQoSInfo const& qos, TFTInfo const& tft)
: stBearerQoS(qos), stTFTInfo(tft)
{ }
};
listOfPolicyRuleInfo m_mlistOfCliConfiguredPolicyRules =
boost::assign::map_list_of("PolicyRule_Fred", PolicyRuleInfo( BearerQoSInfo(9), TFTInfo()))
("PolicyRule_Voice_C", PolicyRuleInfo( BearerQoSInfo(5), TFTInfo()))
("PolicyRule_Voice_U", PolicyRuleInfo( BearerQoSInfo(1), TFTInfo()));

Above are the data strutures. Now within the code somewhere ,

listOfPolicyRuleInfo::iterator it = m_mlistOfCliConfiguredPolicyRules.find("PolicyRule _Fred");

I get error when i try to print the contents of it.

on gdb i see the list

(gdb)p m_mlistOfCliConfiguredPolicyRules
["PolicyRule_Fred"] = {stBearerQoS = {nQCI = 9, nMaxUlBitRate = 0, nMaxDlBitRate = 0,

["PolicyRule_Voice_U"] = {stBearerQoS = {nQCI = 1, nMaxUlBitRate = 0, nMaxDlBitRate = 0,
nGuarUlBitRate = 0, nGuarDlBitRate = 0, nPriorityLevel = 15,

But
(gdb) p it

Could some c++ stl experts help me with this issue please ?

thanks,

boost::assign::map_list_of("PolicyRule_Fred", PolicyRuleInfo( BearerQoSInfo(9), TFTInfo()))

// 

listOfPolicyRuleInfo::iterator it = m_mlistOfCliConfiguredPolicyRules.find("PolicyRule _Fred");

Did you check that 'it' is not equal to m_mlistOfCliConfiguredPolicyRules.end() ?

Note: in the argument to find, you have a space between "e" and "_" .
Should it be there ?

[pdk5]

Thanks a lot for reply and hint.

Now while trying to debug, i have further reduced the changed the map structure to "unsigned int" to see if any issues in memory leaks...

Now changed the structure

// .h
typedef map<u8, u8> listOfPolicyRuleInfo;
class CPCRFublic CBaseClass
{
static map<u8, u8> m_mlistOfCliConfiguredPolicyRules;
}

//.cpp
std::map<u8, u8> m_mlistOfCliConfiguredPolicyRules = boost::assign::map_list_of(Apn_Fred, 9);

void CPCRF::GxCCRequest(string imsi, bool isDefBearerCreation, string sApn, const BearerQoSInfo & stBearerQoS, CIPAddress ueIPAddress, BearerQoSInfo & stBearerQoSNegotiated)
{
switch(getApnCode(sApn))
{
case Apn_Fred:
{
listOfPolicyRuleInfo::iterator it = m_mlistOfCliConfiguredPolicyRules.find(Apn_Fred);
}
// Another .cpp file
std::map<u8, u8>::iterator it = CPCRF::m_mlistOfCliConfiguredPolicyRules.find(nApn);

if (it != CPCRF::m_mlistOfCliConfiguredPolicyRules.end())
{
sPolicyName = it->first;
// stQOS = it->second.stBearerQoS;
}
}

Another.cpp CGxDia.cpp:353: undefined reference to `CPCRF::m_mlistOfCliConfiguredPolicyRules'

while linking i get the above error...

Am i doing something basic wrong/..

[Philip Nicoletti]

You have:

//.cpp
std::map<u8, u8> m_mlistOfCliConfiguredPolicyRules = boost::assign::map_list_of(Apn_Fred, 9);

I am guessing it should be:

//.cpp
std::map<u8, u8> CPCRF::m_mlistOfCliConfiguredPolicyRules = boost::assign::map_list_of(Apn_Fred, 9);

Just a small point. When posting code, please use code tags so that the code is readable! Go Advanced, select the formatted code and click '#'.

[pdk5]

You are amazingly brilliant ! . This issue is fixed (at least the linking), now i need to revert to earlier code
How do I add reputation here ?

[pdk5]

Reverted back to original code ..now

listOfPolicyRuleInfo CPCRF::m_mlistOfCliConfiguredPolicyRules = boost::assign::map_list_of
("PolicyRule_Fred", PolicyRuleInfo( BearerQoSInfo(9), TFTInfo()))
("PolicyRule_Voice_C", PolicyRuleInfo( BearerQoSInfo(5), TFTInfo()))
("PolicyRule_Voice_U", PolicyRuleInfo( BearerQoSInfo(1), TFTInfo()));

But at listOfPolicyRuleInfo::iterator it = CPCRF::m_mlistOfCliConfiguredPolicyRules.find("PolicyRule_Fred");

getting compilation error

ransrc/CGxDia.cpp:351: error: invalid conversion from 'const char*' to 'unsigned char'

sorry for the basic questions, but i am bit poort in c++/stl

[pdk5]

sorry my mistake , have not changed this all places

[pdk5]

Had not changed in the declaration in the class
class CPCRF
{
static listOfPolicyRuleInfo m_mlistOfCliConfiguredPolicyRules;
}

from // static map<u8, u8> m_mlistOfCliConfiguredPolicyRules;

Now the issue is resolved..

This was mainly due to

listOfPolicyRuleInfo CPCRF::m_mlistOfCliConfiguredPolicyRules = boost::assign::map_list_of("PolicyRule_Fred", PolicyRuleInfo( BearerQoSInfo(9), TFTInfo()))

was defined as :

listOfPolicyRuleInfo m_mlistOfCliConfiguredPolicyRules = boost::assign::map_list_of("PolicyRule_Fred", PolicyRuleInfo( BearerQoSInfo(9), TFTInfo()))

Thanks a lot Philip for the quickly pointing out this issue ..
