public VersionUtil()

Method Detail

isVersion

public static boolean isVersion(java.lang.String unknown)

Tests if the unknown string contains elements that identify it as a version string (or not).

The algorithm tests each part of the string that is delimited by a '-' (dash) character. If 75% or more of the sections are identified as 'version' strings, the result is determined to be of a high probability to be version identifier string.

Parameters:

unknown - the unknown string to test.

Returns:

true if the unknown string is likely a version string.

isSimpleVersionKeyword

public static boolean isSimpleVersionKeyword(java.lang.String identifier)

Tests if the identifier is a known simple version keyword.

This method is different from isVersion(String) in that it tests the whole input string in one go as a simple identifier. (eg "alpha", "1.0", "beta", "debug", "latest", "rc#", etc...)

Parameters:

identifier - the identifier to test.

Returns:

true if the unknown string is likely a version string.

isSnapshot

public static boolean isSnapshot(java.lang.String version)

getBaseVersion

public static java.lang.String getBaseVersion(java.lang.String version)

getReleaseVersion

public static java.lang.String getReleaseVersion(java.lang.String snapshotVersion)

Get the release version of the snapshot version.

If snapshot version is 1.0-SNAPSHOT, then release version would be 1.0 And if snapshot version is 1.0-20070113.163208-1.jar, then release version would still be 1.0

Parameters:

snapshotVersion -

Returns:

isUniqueSnapshot

public static boolean isUniqueSnapshot(java.lang.String version)

isGenericSnapshot

public static boolean isGenericSnapshot(java.lang.String version)
