Constructor Detail

ClusterGraphService

public ClusterGraphService(String s3CredentialsFilename,
                           Boolean workOffline,
                           String bucket)

Method Detail

getRouter

public Router getRouter(String graphId)

Overrides:

getRouter in class GraphService

Returns:

the graph object for the given router ID

addGraphFile

public void addGraphFile(File graphFile)
                  throws IOException

Throws:

IOException

getZippedGraph

public File getZippedGraph(String graphId)
                    throws IOException

Throws:

IOException

evictAll

public int evictAll()

Description copied from class: GraphService

Dissocate all graphs from their router IDs and release references to the graphs to allow garbage collection. Routing will not be possible until new graphs are registered. This is equivalent to calling evictGraph on every registered router ID.

Overrides:

evictAll in class GraphService

getRouterIds

public Collection<String> getRouterIds()

Overrides:

getRouterIds in class GraphService

Returns:

a collection of all valid router IDs for this server

getGraphSourceFactory

public GraphSource.Factory getGraphSourceFactory()

Overrides:

getGraphSourceFactory in class GraphService

Returns:

The default GraphSource factory. Needed in case someone want to register or save a new router with a router ID only (namely, via the web-service API).

registerGraph

public boolean registerGraph(String arg0,
                             GraphSource arg1)

Description copied from class: GraphService

Blocking method to associate the specified router ID with the corresponding graph source, load it from appropriate source (serialized file, memory...), and enable its use in routing. The relationship between router IDs and paths in the filesystem is determined by the GraphSource implementation.

Overrides:

registerGraph in class GraphService

Returns:

whether the operation completed successfully

setDefaultRouterId

public void setDefaultRouterId(String arg0)

Overrides:

setDefaultRouterId in class GraphService

Parameters:

arg0 - The ID of the default router to return when no one is specified
