org.apache.jackrabbit.vault.packaging.VersionRange

public class VersionRange
extends java.lang.Object

Implements a version range The string representation is either

• the empty string, which means all versions match
• or a simple version string consisting of arbitrarily many alphanumeric segments separated by .. Those segments must not include a ,. This means everything from the given version will match (i.e. upper bound unlimited).
• or a real range in the form '['|'('<lowerBound>,(<upperBound>']'|')'), where [] means inclusive and () means exclusive bounds. Both the lowerBound and upperBound must follow the grammar from the simple version string.

Since:

2.0
