1.1 | 1 | The [[XAR Module>>doc:extensions:Extension.XAR Module]] is the API XWiki reads and writes [[XAR archives>>doc:documentation.xs.admin.exports.export-content-xar-format.format-specifications.WebHome]] with, and the one to use to inspect an archive without importing it. |
| 2 | |||
| 3 | Reading an archive yields the package information of its [[##package.xml## descriptor>>doc:documentation.xs.admin.exports.export-content-xar-format.format-specifications.WebHome]] and one entry per [[Page file>>doc:documentation.xs.admin.exports.export-content-xar-format.format-specifications.document-xml.WebHome]] it holds. How much of the archive is opened depends on the entry point: ##XarPackage## parses the descriptor and lists the entries, while ##XarFile## also gives access to the XML of a chosen Page. | ||
| 4 | |||
| 5 | Wiki pages reach the API through the [[XAR Script Service>>documentation.xs.dev.xar.script-service.WebHome]]. Java code uses the classes of the ##xwiki-platform-xar-model## module, whose sources are in {{scm path="xwiki-platform-core/xwiki-platform-xar/xwiki-platform-xar-model"/}}. | ||
