void | load (std::istream &) |
Load the mapping from the file at creation when the file exists. Store it at deletion so it could be used later, or loaded in a database using a LOAD DATA INFILE SQL command.
Factory
parameter. tool::mapping< Key, Value, Factory >::mapping | ( | const std::string & | , | |
const Factory & | factory = Factory() | |||
) |
Construct the mapping given the database file's name.
void tool::mapping< K, V, F >::load | ( | std::istream & | in | ) | [inline, protected] |
Load a mapping from an std::istream
.
tool::datafile::operator std::ostream & | ( | ) | [inline, inherited] |
Retrieve the underlying C++ stream.
std::ostream & tool::datafile::operator<< | ( | const T & | data | ) | [inline, inherited] |
Formatted output.
const Value& tool::mapping< Key, Value, Factory >::operator[] | ( | const Key & | ) |
Retrieve the value of a corresponding key.
When the key already exists in the mapping, just return its value. Else, insert the (key, value) pair according to the Factory
template parameter.
