Method Detail

permissionExists

public boolean permissionExists(SpacePermission permission)

Looks up permission in the cache instance. If it is not found, then it is looked up by the DAO and the result (true or false) is also recorded.

If permission belongs to a space, it is looked up in the Space's own permissions list.

In addition, when lookAheadEnabled is true, #doLookAheadCache will be called and the results cached, provided permission does not belong to a space.

Specified by:

permissionExists in interface DefaultConfluenceAccessManager.AccessManagerPermissionChecker

Specified by:

permissionExists in interface SpacePermissionManager

Overrides:

permissionExists in class DefaultSpacePermissionManager

Parameters:

permission - the SpacePermission to look up

Returns:

true if the permission exists, false otherwise

savePermissionToDao

protected void savePermissionToDao(SpacePermission spacePermission)

Saves permission to the DAO. In addition, this method removes the permission from the cache, to prevent corruption of the cache when there is a transaction rollback (since the cache isn't transactional)

Overrides:

savePermissionToDao in class DefaultSpacePermissionManager

Parameters:

spacePermission - the SpacePermission to save

removePermissionFromDao

protected void removePermissionFromDao(SpacePermission spacePermission)

Removes realPermission from the DAO. In addition, the permission is also removed from the cache.

Overrides:

removePermissionFromDao in class DefaultSpacePermissionManager

Parameters:

spacePermission - the SpacePermission to remove

removeAllPermissionsFromDao

protected void removeAllPermissionsFromDao(Space space)

Overrides:

removeAllPermissionsFromDao in class DefaultSpacePermissionManager

flushCaches

public void flushCaches()

Specified by:

flushCaches in interface SpacePermissionManager

Overrides:

flushCaches in class DefaultSpacePermissionManager

isLookAheadEnabled

public boolean isLookAheadEnabled()

setLookAheadEnabled

public void setLookAheadEnabled(boolean lookAheadEnabled)

hasPermissionNoExemptions

public boolean hasPermissionNoExemptions(String permissionType,
                                         @Nullable
                                         Space space,
                                         @Nullable
                                         com.atlassian.user.User remoteUser)

Description copied from interface: SpacePermissionManager

Returns true if the user has the specified permission on the target space. This method does not allow exemptions for super-users like SpacePermissionManager.hasPermission(String, Space, User) does.

For parameter and return value information, see SpacePermissionManager.hasPermission(String, Space, User).

Specified by:

hasPermissionNoExemptions in interface SpacePermissionManager

Overrides:

hasPermissionNoExemptions in class AbstractSpacePermissionManager

getGroupNamesWithPermission

protected Set<String> getGroupNamesWithPermission(@Nullable
                                                  Space targetSpace,
                                                  String permissionType)

Overrides:

getGroupNamesWithPermission in class DefaultSpacePermissionManager
