Method Detail

logVersion

public static void logVersion()

Logs the application version.

getVersion

public static String getVersion()

Returns the application version.

Returns:

the application version

checkVersion

public static boolean checkVersion(String version,
                   String versionPattern)

Compares the version string against a version pattern. If the version matches the pattern, true will be returned, otherwise false will be returned. The pattern is a comma-separated list of version specifications, where each is one of "", "+", and "-". If any version specification matches, the check is considered as successful.

Parameters:

version - the version

versionPattern - the version pattern

Returns:

true if the pattern matches, false otherwise

compareVersions

public static int compareVersions(String version1,
                  String version2)

Compares the two given version strings. Returns a negative number if the first is smaller than the second, a positive number of the first is greater than the second, 0 if they are equal.

Parameters:

version1 - the first version string

version2 - the second version string

Returns:

an integer determining the relative order of the two version strings

compareVersions

public static int compareVersions(int[] versionInts1,
                  String version2)

Compares the two given version strings. Returns a negative number if the first is smaller than the second, a positive number of the first is greater than the second, 0 if they are equal.

Parameters:

versionInts1 - the first version int array

version2 - the second version string

Returns:

an integer determining the relative order of the two versions

compareVersions

public static int compareVersions(int[] versionInts1,
                  int[] versionInts2)

Compares the two given version integer arrays. Returns a negative number if the first is smaller than the second, a positive number of the first is greater than the second, 0 if they are equal.

Parameters:

versionInts1 - the first version int array

versionInts2 - the second version int array

Returns:

an integer determining the relative order of the two version int arrays
