Method Detail

getRecommendedVersion

public ArtifactVersion getRecommendedVersion()

getRestrictions

public java.util.List<Restriction> getRestrictions()

cloneOf

public VersionRange cloneOf()

newRange

public static VersionRange newRange(ArtifactVersion version,
                                    java.util.List<Restriction> restrictions)

Factory method, for custom versioning schemes

Parameters:

version - version

restrictions - restriction list

Returns:

a new version range

createFromVersionSpec

public static VersionRange createFromVersionSpec(java.lang.String spec)
                                          throws InvalidVersionSpecificationException

Create a version range from a string representation

Some spec examples are

• 1.0 Version 1.0
• [1.0,2.0) Versions 1.0 (included) to 2.0 (not included)
• [1.0,2.0] Versions 1.0 to 2.0 (both included)
• [1.5,) Versions 1.5 and higher
• (,1.0],[1.2,) Versions up to 1.0 (included) and 1.2 or higher

Parameters:

spec - string representation of a version or version range

Returns:

a new VersionRange object that represents the spec

Throws:

InvalidVersionSpecificationException

createFromVersion

public static VersionRange createFromVersion(java.lang.String version,
                                             ArtifactVersion existing)

restrict

public VersionRange restrict(VersionRange restriction)

Creates and returns a new VersionRange that is a restriction of this version range and the specified version range.

Note: Precedence is given to the recommended version from this version range over the recommended version from the specified version range.

Parameters:

restriction - the VersionRange that will be used to restrict this version range.

Returns:

the VersionRange that is a restriction of this version range and the specified version range.

The restrictions of the returned version range will be an intersection of the restrictions of this version range and the specified version range if both version ranges have restrictions. Otherwise, the restrictions on the returned range will be empty.

The recommended version of the returned version range will be the recommended version of this version range, provided that ranges falls within the intersected restrictions. If the restrictions are empty, this version range's recommended version is used if it is not null. If it is null, the specified version range's recommended version is used (provided it is non-null). If no recommended version can be obtained, the returned version range's recommended version is set to null.

Throws:

java.lang.NullPointerException - if the specified VersionRange is null.
