private Version()
- Non-instantiable class.
meetsRequirement
public static final boolean meetsRequirement(java.lang.String requiredVersion,
java.lang.String testVersion)
- Tests to see if a version number meets or exceeds a requirement.
For example, if version 1.4 is required, 1.4, 1.4.0, 1.4.1, 1.5,
and 2.0 would meet the requirement. 0.7, 1, 1.0, 1.3, and
1.3.5 would not. Warning: At this time all versions must be numeric and
separated by periods. Any deviation will result in .0 versions, such as
1.5.3b being calculated as 1.5.0.
getTokenValue
private static final int getTokenValue(java.lang.String token)
- Returns a best guess translation of a string to an integer.
If the string is not numeric, zero is returned.
