Class TVersion

TVersion

Support

Supported from 5.0

Description

Contains version information.

A version is defined by a set of three numbers:

• the major version number, ranging from 0 to 127, inclusive

• the minor version number, ranging from 0 to 99 inclusive

• the build number, ranging from 0 to 32767 inclusive.

The class provides a constructor for setting all three numbers. It also provides a member function to build a character representation of this information in a TVersionName descriptor.

Defined in TVersion:
Name(), TVersion(), TVersion(), iBuild, iMajor, iMinor

TVersion();

Description

Default constructor.

Sets the major, minor and build numbers to zero.

TVersion(TInt aMajor,TInt aMinor,TInt aBuild);

Description

Constructs the object with the specified major version number, the minor version number and the build number.

Parameters

Notes:

• The constructor does not check that the values passed are within the specified ranges. As the parameters are TInt types, care must be taken to ensure that values passed do not exceed the specified maximum, otherwise they will be interpreted as negative values.

TVersionName Name();

Description

Gets a descriptor buffer containing the formatted character representation of the version information.

The general format of the representation is: xxx.yy(zzzzz)

where:

• xxx is the major version number; depending on the value, this may have a length of one, two or three characters

• yy is the minor version number; this is always two characters, padded with a leading zero, if necessary

• zzzzz is the build number; depending on the value, this may have a length of one to 5 characters.

Return value

Notes:

• If the object is constructed with values that exceed the permitted range, they will appear negative in their formatted character representation.
