ur_rna.Utilities.Version

All Implemented Interfaces:

java.lang.Comparable<Version>

public class Version
extends java.lang.Object

Method Detail

compareTo

public int compareTo(Version o)

Specified by:

compareTo in interface java.lang.Comparable<Version>

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

isEmpty

public boolean isEmpty()

isVersionCompatible

public static boolean isVersionCompatible(java.lang.String minVersion,

toString

public java.lang.String toString()

Overrides:

tryParse

public static Version tryParse(java.lang.String version)

Returns a Version object if the passed-in String argument represents a valid version string. Otherwise, returns null. This function prints an error to STDERR (via Throwable.printStackTrace) if the version cannot be parsed.

Parameters:

version - A string representing a version number, e.g. 2.3.1 A version string must have at least two parts (e.g. 6.0) but not more than four parts (e.g. 6.0.2.8888) The version string can be empty or null, in which case null is returned.

Returns:

Null if the version string is invalid, empty, or null. Otherwise returns a version object.
