Detailed Description

Class to parse attribute-assignments from a string and sets its values into attribute-values.

Use this class like the following:

std::string file;
    ANumeric    size;
    ATimestamp  time;

    AttributeParse attrs;
    ATTRIBUTE (attrs, std::string, file, "File");
    ATTRIBUTE (attrs, ANumeric, size, "Size");
    ATTRIBUTE (attrs, ATimestamp, time, "Time");

    try {
       attrs.assignValues ("File=\"ADate.cpp\";Time=01012000 121005;Size=18180");
    }
    catch (YGP::ParseError& e) {
       // Errorhandling
    }

This example would assign the values ADate.cpp to file, 18180 to size and the 1st of January 2000, 12:10:05 to time.

MEATTRIBUTE defines an attribute whose values are restricted to the values in the respective YGP::MetaEnum.

Note:

Tthe order of the attributes while declaration and during parsing does not need to be the same!
