Detailed Description

Class that wraps up version numbers and logic

We have a hierarchy of three release numbers, these are...

  • major - represents the product series, eg "5"
  • minor - represents a specific release in the series, all versions with the same minor number are compatible, eg "5.0"
  • release - represents a specific release of a minor number typically to fix bugs. eg "5.0.0"

With this logic 5.0.0 and 5.0.1 are compatible versions that work the same way, but with 5.0.1 having bugs fixed and so on.

To manage alpha/beta builds we also have a 'phase', which indicates whether the software is in development, alpha, beta or release. If the software is not in release, we have to have a fourth number indicating the alpha/beta number.

The final number is the build number, which represents the current repository version.

We also have logic to turn a version into and out of a string as well a comparison to see which release is greater than another.

So,

  • an alpha build will look like "5.0v3.000004a"
  • an beta build will look like "5.0v3.000004b"
  • a release build will look like "5.0v3"

The string that represents the version number fits the following regex... (0..9)+"."(0..9)+"v"(0..9)+[(d|a|b|p)(0..9)+]

NOTE: there is special case for version comparisons for dev builds. A dev build is considered not less than or greater than any other build for the same major and minor version, but not equal to either. This is because dev versions can (in theory) proceed right through from v1a1 to full release of v99 and still not provide incompatibilities, and any incompatibility still wouldn't be detected by the current system of having dev builds at v0. e. g. 5.2v0d0 < 5.2v1 is false; 5.2v0d0 > 5.2v1 is false; 5.2v0d0 == 5.2v1 is false. Still, 5.2v0d0 < 5.3v1 is true, etc.

Constructor & Destructor Documentation

◆ Version() [1/3]

DD::Image::Version::Version ( const char *  buildDate = __DATE__)

default ctor, sets to the minimum version

make an empty which defaults to 0.0v0a1

NEVER OVERRIDE THE DATE. THIS IS THE MECHANISM WE USE TO BE SURE THE BUILD DATE IS THE DATE THE OBJECT WAS COMPILED, NOT THE DATE THE LIBRARY WAS COMPILED. (Yes I am shouting.)

◆ Version() [2/3]

DD::Image::Version::Version ( const char *  version,
unsigned int  major,
unsigned int  minor,
unsigned int  release,
PhaseEnum  phase,
unsigned int  phaseNumber,
bool  is64bit,
unsigned int  buildNumber,
const char *  date = __DATE__ 
)

make the version

NEVER OVERRIDE THE DATE. THIS IS THE MECHANISM WE USE TO BE SURE THE BUILD DATE IS THE DATE THE OBJECT WAS COMPILED, NOT THE DATE THE LIBRARY WAS COMPILED. (Yes I am shouting.)

◆ Version() [3/3]

DD::Image::Version::Version ( const std::string &  v,
const char *  date = __DATE__ 
)

make it from a std::string. This breaks it down into fields. NOTE: must be an explicit std::string, as passing a const char* will use a different constructor.

Member Function Documentation

◆ isCompatible()

bool DD::Image::Version::isCompatible ( const Version v) const
inline

is the other version compatible with this version

  • ie: are the major & minor numbers the same

References majorNumber(), and minorNumber().

◆ string()

std::string DD::Image::Version::string ( ) const

Return equivalent of string passed to constructor.

Return the string description of major, minor, release, and phase. Does not include date or bits

References majorNumber(), minorNumber(), phase(), phaseStringFull(), and releaseNumber().

Referenced by DD::Image::VersionStreamPut().

◆ majorMinorString()

std::string DD::Image::Version::majorMinorString ( ) const

Returns the major and minor numbers in a double-style string

  • e. g. 5.1 for 5.1v*

References majorNumber(), and minorNumber().

◆ majorMinorReleaseString()

std::string DD::Image::Version::majorMinorReleaseString ( ) const

Returns the major, minor, and release numbers in a string

  • e. g. 5.1v2 for 5.1v2*

References majorNumber(), minorNumber(), and releaseNumber().

◆ releasePhaseString()

std::string DD::Image::Version::releasePhaseString ( ) const

Returns the release and phase identifiers in a string

  • e. g. v1.000007b for ?.?v1.000007b

References phaseStringFull(), and releaseNumber().

◆ doubleString()

std::string DD::Image::Version::doubleString ( ) const

Returns a string version of majorMinorReleasePhaseDouble(). 5.1v2b3 returns "5.102000003". Deprecated. Please avoid using double strings.

References majorMinorReleasePhaseDouble().

◆ majorMinorReleasePhaseInteger()

long long DD::Image::Version::majorMinorReleasePhaseInteger ( ) const

Return an integer representation of the major, minor, release, and build. This number will increase for a "newer" version, and is the value of the kDDImageVersionInteger macro. 5.1v2.000003b returns 5102000003. Note however that 5.1v2 returns 51200, so direct integer comparisons of version numbers are not completely reliable. Deprecated. Please use the class comparison methods instead.

◆ majorMinorReleasePhaseDouble()

double DD::Image::Version::majorMinorReleasePhaseDouble ( ) const

Returns a double version of majorMinorReleasePhaseInteger(). 5.1v2.000003b returns 5.102000003. Deprecated. Please use the class comparison methods instead.

References majorMinorReleasePhaseInteger().

◆ majMinRelPhaseStr()

std::string DD::Image::Version::majMinRelPhaseStr ( void  ) const
inline

Simple testing function - check by reading output.

same as string(); for back-compatibility
