3 The syntax is mostly based on the Maven one.

5 |=Range|=Meaning
6 |1.0|1.0 is best but greater version are matched too.
7 {{warning}}in Maven it means 1.0 is best but any other version is matched too{{/warning}}
8 |(,1.0]|x <= 1.0
9 |[1.0]|Only 1.0
10 |[1.2,1.3]|1.2 <= x <= 1.3
11 |[1.0,2.0)|1.0 <= x < 2.0
12 |[1.5,)|x >= 1.5
13 |(,1.0],[1.2,)|x <= 1.0 or x >= 1.2. Multiple sets are comma-separated
14 |(,1.1),(1.1,)|Anything but 1.1

16 In Java these version are represented by the following public interfaces:
17 * ##org.xwiki.extension.version.Version##: provide API to compare versions and indicate if the version is of type SNAPSHOT, BETA or STABLE
18 * ##org.xwiki.extension.version.VersionRange##: a single range
19 * ##org.xwiki.extension.version.VersionRangeCollection##: several ranges
20 * ##org.xwiki.extension.version.Constraint##: a VersionRangeCollection or a Version
21
22 {{info}}This is the default syntax used by Extension Manager but it's each repository handler job to parse it's own syntax and create corresponding Java objects implementing Extension Manager public API.{{/info}}
