Constructor Detail

Version

public Version(java.lang.String bundle,
               java.lang.String pkg)

This constructor builds a Version object given a resource bundle name and a package name. It assumes there are <pkg>.version.major, <pkg>.version.minor, <pkg>.release.date.pattern and <pkg>.release.date properties. If some are missing, or the pattern of the date does not let parse the release date, the corresponding values will be null. If the date pattern is not available, the DEFAULT_DATE_PATTERN is used.

Parameters:

bundle - - the bundle name

pkg - - the package name, which is the prefix used to get the version information properties in the bundle (e.g. "acm" is prefixed to get "version.major" for ACM)

getReleaseDate

public java.util.Date getReleaseDate()

This method returns the date of releasing the package, as recorded in the resource bundle.
