Interface VersionConstraint

public interface VersionConstraint

A constraint on versions for a dependency. A constraint can either consist of a version range (e.g. "[1, ]") or a single version (e.g. "1.1"). In the first case, the constraint expresses a hard requirement on a version matching the range. In the second case, the constraint expresses a soft requirement on a specific version (i.e. a recommendation).

Method Summary

Modifier and Type	Method	Description
boolean	containsVersion(Version version)	Determines whether the specified version satisfies this constraint.
VersionRange	getRange()	Gets the version range of this constraint.
Version	getVersion()	Gets the version recommended by this constraint.

Method Detail

getRange

VersionRange getRange()

Gets the version range of this constraint.

Returns:

The version range or null if none.

getVersion

Version getVersion()

Gets the version recommended by this constraint.

Returns:

The recommended version or null if none.

containsVersion

boolean containsVersion(Version version)

Determines whether the specified version satisfies this constraint. In more detail, a version satisfies this constraint if it matches its version range or if this constraint has no version range and the specified version equals the version recommended by the constraint.

Parameters:

version - The version to test, must not be null.

Returns:

true if the specified version satisfies this constraint, false otherwise.
