public static void requireVersion(String version)

Version must be of form "M.N[.K]" where M is major version, N is minor version and K is increment. This method returns true if current major version is the same and minor is bigger or equal to current minor version. If provided major and minor versions are equals to current version then increment is also checked and check is passed when increment is bigger or equal to current increment version.

Throws:

IllegalStateException

parseVersion

public static int[] parseVersion(String version)
                          throws NumberFormatException

Parse version string N.M[.K] into three subcomponents (M=major,N=minor,K=increment) that are returned in array with three elements. M and N must be non negative, and K if present must be positive integer. Increment K is optional and if not present in version string then it is assumed as zero.

Throws:

NumberFormatException
