Class Version
java.lang.Object
gov.llnl.babel.symbols.Version
public class Version
extends java.lang.Object
Class Version
represents a symbol version of the general
form "V1.V2...Vn" where Vi is a non-negative integer. Trailing zeros
in the version number are not significant. That is, "1.2" is the same
as "1.2.0" and "1.2.0.0.0".
Version() - Create a new
Version class that will be constructed
through member function appendVersionNumber .
|
Version(String version) - Create a new
Version class by parsing a version string
of the form "V1.V2...Vn" where each Vi is a non-negative integer.
|
void | appendVersionNumber(int v) - Add another version number to the existing version description.
|
int | getVersionLength() - Return the number of sub-parts in the version description.
|
int | getVersionNumberAt(int i) - Return the version number at a particular location of the version
string using zero-based indexing.
|
String | getVersionString() - Return the current version description as a version string.
|
int | hashCode() - Return a hash code for a version.
|
boolean | isGreaterThan(Version other) - Return whether this version is greater than the version in the
argument.
|
boolean | isSame(Version other) - Return whether two version objects represent the same version
number.
|
boolean | isUnspecified()

Version
public Version()
Create a new Version
class that will be constructed
through member function appendVersionNumber
. An empty
version is considered to be version "0".
Version
public Version(String version)
throws NumberFormatException
Create a new Version
class by parsing a version string
of the form "V1.V2...Vn" where each Vi is a non-negative integer.
If the version is not of this form, then the constructor throws a
NumberFormatException
.
appendVersionNumber
public void appendVersionNumber(int v)
Add another version number to the existing version description. If
current version is "V1.V2...Vn" and this number is Vm, then the new
version description will be "V1.V2...Vn.Vm". If the version is a
non-negative integer, then a NumberFormatException
is
thrown.
getVersionLength
public int getVersionLength()
Return the number of sub-parts in the version description. For a
version string "V1.V2...Vn", this routine returns the value of n.
getVersionNumberAt
public int getVersionNumberAt(int i)
Return the version number at a particular location of the version
string using zero-based indexing. If the requested index is less
than zero or is equal to or greater than the version length, then
zero is returned.
getVersionString
public String getVersionString()
Return the current version description as a version string. If no
version has been set, then the returned version is "0". Otherwise,
the version is of the form "V1.V2...Vn".
hashCode
public int hashCode()
Return a hash code for a version.
isGreaterThan
public boolean isGreaterThan(Version other)
Return whether this version is greater than the version in the
argument. Version "W1.W2...Wn" is considered greater than version
"V1.V2...Vn" if for some i, Wj equals Vj for all j less than i and
Wi is greater than Vi. If the two versions have different lengths,
then the shorter version is padded with zeros.
isSame
public boolean isSame(Version other)
Return whether two version objects represent the same version
number. Note that version "1.2.0" is considered the same as
"1.2" since trailing zeros are ignored.
isUnspecified
public boolean isUnspecified()
