GammaLib

The GUrl abstract base class has been implemented that defines the standard interface for the URL classes:

class GUrl : public GBase {
public:
    // Constructors and destructors
    GUrl(void);
    GUrl(const GUrl& url);
    virtual ~GUrl(void);

    // Operators
    GUrl& operator=(const GUrl& url);

    // Pure virtual methods
    virtual void        clear(void) = 0;
    virtual GUrl*       clone(void) const = 0;
    virtual void        open(const std::string& url, const std::string& mode) = 0;
    virtual void        close(void) = 0;
    virtual int         read(void* buffer, const int& nbyte) = 0;
    virtual int         write(const void* buffer, const int& nbyte) = 0;
    virtual int         getchar(void) = 0;
    virtual void        putchar(const int& character) = 0;
    virtual void        scanf(const char* format, ...) = 0;
    virtual void        printf(const char* format, ...) = 0;
    virtual std::string print(void) const = 0;
};

The GUrlFile class has been implemented that handles flat files. Unit tests have been added for C++ and Python to validate the class. Note that the Python interface differs slightly from the C++ interface. In particular, the scanf() and printf() methods are so far missing. We may see later how those could be implemented. I guess this requires some deep SWIG coding.

The class GUrlString has been added for reading and writing to strings. This completes the functionality that is needed for the moment, hence the feature can be closed.

Note that the printf() method has an internal buffer limitation and the scanf() method does not advance the internal pointer, hence printf() can be used with limitations and scanf() cannot really be used.
