All Implemented Interfaces:

Comparable<AGServerVersion>

public final class AGServerVersion
extends Object
implements Comparable<AGServerVersion>

AllegroGraph server version number. A version is constructed from string containing a sequence of numbers separated by non-digit characters. The main purpose of this class is to allow version numbers to be compared. Note that only numeric components are compared, all other characters are ignored. All trailing zeros are stripped, so version "6.0.0" is considered to be equal to "6" and "6.0".

Constructor Detail

AGServerVersion

public AGServerVersion(String versionString)

Parses a version string and constructs a version object.

Parameters:

versionString - String to be parsed, must consist of a sequence of numbers separated by non-digit characters,

Method Detail

compareTo

public int compareTo(AGServerVersion other)

Performs a lexicographic comparison with another version number. Note that only numerical components are considered, all other characters from the original version strings are ignored. Any trailing zeros are also ignored, so "6.0" will be considered equal to "6.0.0" and "6".

Specified by:

compareTo in interface Comparable<AGServerVersion>

Parameters:

other - The version to compare with.

Returns:

See Comparable.compareTo(Object)

Throws:

NullPointerException - if the other version is null.

equals

public boolean equals(Object other)

Checks if another object represents the same version number. Note that only numerical components are considered, all other characters from the original version strings are ignored. Any trailing zeros are also ignored, so "6.0" will be considered equal to "6.0.0" and "6". If the other object is null or not an AGServerVersion false will be returned.

Overrides:

equals in class Object

Parameters:

other - The object to compare to.

Returns:

True if the other object represents the same version, false otherwise.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
