Class VersionRange

java.lang.Object
net.adoptopenjdk.icedteaweb.jnlp.version.VersionRange
public class VersionRange extends Object
A version-range is either a version-id, a version-id followed by a star (*), a version-id followed by a plus sign (+) , or two version-ranges combined using an ampersand (&). The star means prefix match, the plus sign means this version or greater, and the ampersand means the logical and-ing of the two version-ranges.

The syntax of version-strings is: 

     version-string     ::=  version-range ( " " element) *
     version-range      ::=  simple-range ( "&" simple-range) *
     simple-range       ::=  version-id | version-id modifier
     modifier           ::=  "+" | "*"

See JSR-56 Specification, Appendix A.
