Detailed Description

Useful for representing versions. The versions are represented as a triplet composed of a major number, a minor number and a release number. Different major numbers means that two versions are uncompatible. The minor version number means ascending compatibility. The release number versions only denotes different debugging versions (no change in the interface of a compilation unit).

Constructor & Destructor Documentation

Version() [1/5]

Version ( int  major = 0, int  minor = 0, int  release = 0  )

inline

Build a new version.

Parameters

major	Major number.
minor	Minor number.
release	Release number.

Version() [2/5]

Version ( const Version &  version )

inline

Build a version by cloning.

Parameters

version

Cloned version.

Version() [3/5]

Version ( const char *  text )

inline

Version() [4/5]

Version ( const cstring  text )

inline

Version() [5/5]

Version ( const string &  text )

inline

Build a version from a string.

operator=(const string& text)

Parameters

text	String to build from.

Member Function Documentation

accepts()

bool accepts ( const Version &  version ) const

inline

Test if the current version accepts the given one, that is, the current one is ascendent-compatible with the given one.

Parameters

version

Version to compare with.

compare()

int compare ( const Version &  version ) const

inline

Compare two versions. Notice that comparison is only performed on major and minor numbers.

Parameters

version

Version to compare with.

Returns

0 for equality, <0 if current is less than passed one, >0 else.

Version & operator=

(

const string &

text

)

Set a version from a text string. The text string must have the following form: [0-9]+(.[0-9]+([0-9]+)?)?. If the string does not match, the version 0.0.0 is set.

Parameters

text	Text containing the version.

Returns

Current version.
