Detailed Description

a container for keyword/value pairs

The measures class is a generic container for string/value pairs. It can be used for any purpose but was constructed to make it easy to collect computed measures into a single structure for output.

Measures accepts a string as the keyword. The value part can an int, a double or a string. Any values that can be automatically converted to one of these types is also accepted.

The measures class is a vector type and can contain an unlimited number of string/value pairs. The pairs are initialized by calling the entry member function to add a new pair to the measures object.

Example:

    measures    myExperimentalMeasures;

    int lanex=4;
    myExperimentalMeasures.entry("lane deviations",lanex);

    float laneStdDev=7.2;
    myExperimentalMeasures.entry("lane std. dev.", laneStdDev);

    myExperimentalMeasures.entry("lane departure direction", "Left");

Two output functions are provided: operator<<(std::ostream&,const measures&) and print_labels()

Examples:

campAnalysis.cpp, campVIRTTEXAnalysis.cpp, and hmi04.cpp.
