java.lang.Objectcom.jogamp.common.util.VersionNumber
public class VersionNumber
Simple version number class containing a version number
either being defined explicit
or derived from a string
.
For the latter case, you can query whether a component has been defined explicitly by the given versionString
,
via hasMajor()
, hasMinor()
and hasSub()
.
The state whether a component is defined explicitly is not considered
in the hashCode()
, equals(Object)
or compareTo(Object)
methods,
since the version number itself is treated regardless.

Method Detail |

public static Pattern getVersionNumberPattern(String delim)
pattern
with Perl regular expression:
"\\D*(\\d+)[^\\"+delim+"\\s]*(?:\\"+delim+"\\D*(\\d+)[^\\"+delim+"\\s]*(?:\\"+delim+"\\D*(\\d+))?)?"
A whitespace within the version number will end the parser.
Capture groups represent the major (1), optional minor (2) and optional sub version number (3) component in this order.
Each capture group ignores any leading non-digit and uses only contiguous digits, i.e. ignores pending non-digits.
delim
- the delimiter, e.g. "."public static Pattern getDefaultVersionNumberPattern()
pattern
using getVersionNumberPattern(String)
with delimiter ".".
Instance is cached.
public final boolean isZero()
true
, if all version components are zero, otherwise false
.
public final boolean hasMajor()
true
, if the major component is defined explicitly, otherwise false
. Undefined components has the value 0
.
public final boolean hasMinor()
true
, if the optional minor component is defined explicitly, otherwise false
. Undefined components has the value 0
.
public final boolean hasSub()
true
, if the optional sub component is defined explicitly, otherwise false
. Undefined components has the value 0
.
public final int endOfStringMatch()
version-string
, returns the string offset after the last matching character,
or 0
if none matched, or -1
if not constructed with a string.
