Access to map data
- by herzl shemuelian
I have a complex map that defined
typedef short short1
typedef short short2
typedef map<short1,short2> data_list;
typedef map<string,list> table_list;
I have a class that fill table_list
class GroupingClass
{
table_list m_table_list;
string Buildkey(OD e1){
string ostring;
ostring+=string(e1.m_Date,sizeof(Date));
ostring+=string(e1.m_CT,sizeof(CT));
ostring+=string(e1.m_PT,sizeof(PT));
return ostring;
}
void operator() (const map<short1,short2>::value_type& myPair) {
OptionsDefine e1=myPair.second;
string key=Buildkey(e1);
m_table_list[key][e1.m_short2]=e1.m_short2;
}
operator table_list() {
return m_table_list;
}
};
and I use it by
table_list TL2
GroupingClass gc;
TL2=for_each(mapOD.begin(), mapOD.end(), gc);
but when I try to access to internal map I have problems
for example
data_list tmp;
tmp=TL2["AAAA"];
short i=tmp[1]; //I dont update i variable
but if i use a loop by itrator this work properly
why this no work at first way
thanks herzl
