Description

Version : 0.1

Just a little Id to help us to decide if two thread are running in the same program or just on the same machine or on differen machines.

Datatypes
data SiteId Source
The datatype of the SiteId, it contains the hostname and a processid, so it is possible to decide if two site ids belong to the same process or the the same computer or are on distinct computers.

type SiteMap = Map HostName (Set SiteId)Source
Just a little Map to hold the SiteIds an to get the neighbout Ids.
Operations on the SiteId
getSiteId :: IO SiteIdSource
Gets the SiteId for the calling program.
getSiteHost :: SiteId -> HostNameSource
Extracts the Hostname from the SiteId.
getSiteProcess :: SiteId -> ProcessIDSource
Extracts the ProcessID from the SiteId.
isSameHost :: SiteId -> SiteId -> BoolSource
Test, if the two Ids are located on the same host.
isSameProcess :: SiteId -> SiteId -> BoolSource
Test, if the two Ids are located on the same host an in the same process.
nearestId :: SiteId -> [SiteId] -> Maybe SiteIdSource
Gets the nearest item from an Id-list compared to a given Id.
Operations on the SiteMap
emptySiteMap :: SiteMapSource
Empty SiteId-Map.
addIdToMap :: SiteId -> SiteMap -> SiteMapSource
Adds an id to the map.
deleteIdFromMap :: SiteId -> SiteMap -> SiteMapSource
Deletes an id from the map.
deleteHostFromMap :: HostName -> SiteMap -> SiteMapSource
Delete a hostname an all its ids from the map.
isSiteIdMember :: SiteId -> SiteMap -> BoolSource
Test, if the site id is already in the list.
getNeighbourSiteIds :: SiteId -> SiteMap -> Set SiteIdSource
Gets all ids which are on the same host, but not the original siteid itself.
