    • registerShortcut

      public void registerShortcut(String pluginModuleKey, KeyboardShortcut shortcut)
      Description copied from interface: KeyboardShortcutManager
      Given a complete plugin module key, this method registers a keyboard shortcut with the manager, which will make it available in the UI to end-users.
      Specified by:
      registerShortcut in interface KeyboardShortcutManager
      Parameters:
      pluginModuleKey - the complete plugin module key for this keyboard shortcut
      shortcut - the shortcut to register

    • unregisterShortcut

      public void unregisterShortcut(String pluginModuleKey)
      Description copied from interface: KeyboardShortcutManager
      Removes a keyboard shortcut by its complete plugin module key.
      Specified by:
      unregisterShortcut in interface KeyboardShortcutManager
      Parameters:
      pluginModuleKey - the key to remove

    • listActiveShortcutsUniquePerContext

      public List<KeyboardShortcut> listActiveShortcutsUniquePerContext(Map<String,Object> userContext)
      Description copied from interface: KeyboardShortcutManager
      Returns an ordered list of active KeyboardShortcuts, sorted using the plugin descriptor's order attribute.

      A shortcut is considered active if

      1. All conditions attached to the keyboard shortcut are fulfilled, so that the current user is allowed to use it.
      2. It has not been overridden by another shortcut of the same KeyboardShortcutManager.Context that uses the same key combination and has a greater value in its order attribute (see the keyboard shortcut plugin module documentation). Thus this list can contain multiple shortcuts with the same key combination, which all belong to a different context.

      Be aware, that this operation is potentially expensive, depending on the number and type of conditions attached to the keyboard shortcuts. So store the result in favour of recalculating it.

      Specified by:
      listActiveShortcutsUniquePerContext in interface KeyboardShortcutManager
      Parameters:
      userContext - the context to be used when evaluating, whether the user is allowed to use the shortcut; not null
      Returns:
      ordered list of all active keyboard shortcuts, no duplicate shortcuts per KeyboardShortcutManager.Context; not null

    • getAllShortcuts

      public List<KeyboardShortcut> getAllShortcuts()
      Description copied from interface: KeyboardShortcutManager
      Returns an ordered list of all KeyboardShortcuts available using the plugin descriptor's 'order' attribute for sorting. Implementations should take care to implement this method as quickly as possible since it will be called very often.

      Note this method returns all registered shortcuts, even if they are not in effect (e.g. they have been overridden). This means that this method may return duplicate shortcuts.

      Specified by:
      getAllShortcuts in interface KeyboardShortcutManager
      Returns:
      ordered list of all registered keyboard shortcuts

    • requireShortcutsForContext

      public void requireShortcutsForContext(KeyboardShortcutManager.Context context)
      Description copied from interface: KeyboardShortcutManager
      Register that the keyboard shortcuts for the context should be included by KeyboardShortcutManager.includeShortcuts() (in addition to the global shortcuts, which are always included).
      Specified by:
      requireShortcutsForContext in interface KeyboardShortcutManager
      Parameters:
      context - the context whose keyboard shortcuts should be included (in addition to global).

    • includeShortcuts

      public String includeShortcuts()
      Description copied from interface: KeyboardShortcutManager
      Returns a URL to be used to include the currently registered keyboard shortcuts in a page. The URL should point to the Keyboard Shortcut REST resource. Generally this URL will look something like: /rest/api/1.0/shortcuts/500/f1e3b05a6e6db41e5b77fb8afd7ddde9/shortcuts.js

      It has been suggested that webresources (with say the systemcounter) would be a good fit for this, however the problem is that the systemcounter would have to be updated everytime a plugin is enabled/disabled (so everytime JIRA is started up), which would have some adverse side effects:

      • The system counter would get really large eventually
      • All webresources would no longer be cached after a restart of JIRA and would have to be downloaded again.
      That's why this uses a md5 checksum of the shortcuts in the URL instead of the web-resources approach.

      It does not contain the applications context path. Also, the hash included at the end of the URL should be a hash of all keyboard shortcuts currently available such that the resource can be cached indefinitely. If a new shortcut is registered (or an old shortcut unregistered), then the hash should obviously change.

      Specified by:
      includeShortcuts in interface KeyboardShortcutManager
      Returns:
      URL pointing to a REST resource to included keyboard shortcuts. The URL will be correctly URL-escaped, but it is not HTML escaped.

    • isKeyboardShortcutsEnabled

      public boolean isKeyboardShortcutsEnabled()
      Description copied from interface: KeyboardShortcutManager
      Returns if the user has keyboard shortcuts enabled. If the user is not logged in this will default to true
      Specified by:
      isKeyboardShortcutsEnabled in interface KeyboardShortcutManager
      Returns:
      boolean indicating if the user has keyboard shortcuts enabled. Defaults to true if the user is not logged in.
