/* SunVersion is used to compare java versions based on a string, as taken
|
|
from the registry. The strings look like "1.3", "1.3.1", "1.3.1_02" etc.
|
|
Versions such as "1.4.1_01a" are allowed although this is not specified.
|
|
1.4.1_01 < 1.4.1_01a < 1.4.1_01b < 1.4.1_02
|
|
Pre - release versions, such as 1.4.1-ea, 1.4.1-beta, 1.4.1-rc are recognized,
|
|
but are treated as minor to release versions:
|
|
1.4.0 > 1.4.2-beta
|
|
Pre releases relate this way
|
|
1.4.1-ea < 1.4.1-beta < 1.4.1-rc1
|
|
|
|
An object acts as holder for the version string. That string may be present
|
|
even if the version could not be parsed. Then the version may not be compatible
|
|
to a SUN Java version.
|
|
|
|
An invalid object, that is, operator bool returns false, will always be
|
|
the lower version in a comparison. If two invalid objects are compared
|
|
then they are considered equal.
|
|
|
|
To test if the version is ok, that is this object can be compared to others,
|
|
use the bool conversion operator.
