Hi,
I have the following definition of the classes
class DataRecordMap
{
private:
typedef boost::shared_ptr<const DataRecord >
DataRecordPtr;
typedef std::pair key_type;
typedef double value_type;
struct keyComp
{
bool operator() (const DataRecordMap::key_type
&lhs,
const
DataRecordMap::key_type &rhs) const;
};
private:
typedef std::map map_type;
const std::vector m_index;
map_type m_records;
public:
DataRecordMap(const std::vector &idx);
void add(DataRecordPtr secondKey, double value);
double operator[] (const DataRecord &value) const;
double& operator[] (const DataRecord &secondKey);
friend std::ostream& operator << (std::ostream& out, const
DataRecordMap &records);
};
Then it fails to compile on this implementation:
double DataRecordMap::operator[] (const DataRecord &secondKey) const
{
std::string firstKey(secondKey.compareKey(m_index)->signature());
map_type::const_iterator findIt(std::find_if(m_records.begin(),
m_records.end(),
boost::bind(&map_type::key_type::first, _1) == firstKey));
if(findIt==m_records.end())
THROW_EXCEPTION("Key " << firstKey << " not found in the
data records");
return (*findIt).second;
}
Could someone please help me with it? The error is:
