      • Version

        public Version​(int aMajor,
               int aMinor,
               int aBuild,
               java.lang.String aName)
        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 number
        aMinor - minor version number
        aBuild - build number
        aName - build name, null value becomes empty string

    • Method Detail

      • parse

        public static Version parse​(java.lang.String str)
        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

        public java.lang.String getName()
        Returns:
        build name

      • isGreaterOrEqualTo

        public boolean isGreaterOrEqualTo​(Version other)
        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, and false otherwise

      • isCompatibleWith

        public boolean isCompatibleWith​(Version other)
        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, and false otherwise

      • isEquivalentTo

        public boolean isEquivalentTo​(Version other)
        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, and false otherwise

      • isGreaterThan

        public boolean isGreaterThan​(Version other)
        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, and false otherwise

      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object
        See Also:

        public java.lang.String toString()
        Returns the string representation of this version identifier. The result satisfies version.equals(new Version(version.toString())).
        Overrides:
        toString in class java.lang.Object
        Returns:
        the string representation of this version identifier
