Version
Creates version identifier object from given parts. No validation performed during object instantiation, all values become parts of version identifier as they are.- Parameters:
aMajor
- major version numberaMinor
- minor version numberaBuild
- build numberaName
- build name,null
value becomes empty string

Method Details
-
parse
Parses given string as version identifier. All missing parts will be initialized to 0 or empty string. Parsing starts from left side of the string.- Parameters:
str
- version identifier as string- Returns:
- version identifier object
-
getBuild
public int getBuild()- Returns:
- build number
-
getMajor
public int getMajor()- Returns:
- major version number
-
getMinor
public int getMinor()- Returns:
- minor version number
-
getName
- Returns:
- build name
-
isGreaterOrEqualTo
Compares two version identifiers to see if this one is greater than or equal to the argument.A version identifier is considered to be greater than or equal if its major component is greater than the argument major component, or the major components are equal and its minor component is greater than the argument minor component, or the major and minor components are equal and its build component is greater than the argument build component, or all components are equal.
- Parameters:
other
- the other version identifier- Returns:
true
if this version identifier is compatible with the given version identifier, andfalse
otherwise
-
isCompatibleWith
Compares two version identifiers for compatibility.A version identifier is considered to be compatible if its major component equals to the argument major component, and its minor component is greater than or equal to the argument minor component. If the minor components are equal, than the build component of the version identifier must be greater than or equal to the build component of the argument identifier.
- Parameters:
other
- the other version identifier- Returns:
true
if this version identifier is compatible with the given version identifier, andfalse
otherwise
-
isEquivalentTo
Compares two version identifiers for equivalency.Two version identifiers are considered to be equivalent if their major and minor components equal and are at least at the same build level as the argument.
- Parameters:
other
- the other version identifier- Returns:
true
if this version identifier is equivalent to the given version identifier, andfalse
otherwise
-
isGreaterThan
Compares two version identifiers for order using multi-decimal comparison.- Parameters:
other
- the other version identifier- Returns:
true
if this version identifier is greater than the given version identifier, andfalse
otherwise
-
hashCode
public int hashCode() -
equals
-
toString
Returns the string representation of this version identifier. The result satisfiesversion.equals(new Version(version.toString()))
. -
compareTo
- Specified by:
compareTo
in interfaceComparable<Version>
- Parameters:
obj
- version to compare this instance with- Returns:
- comparison result
