Method Detail

setGraphUpdaterManager

public void setGraphUpdaterManager(GraphUpdaterManager updaterManager)

Description copied from interface: GraphUpdater

Graph updaters must be aware of their manager to be able to execute GraphWriterRunnables. GraphUpdaterConfigurator should take care of calling this function.

configurePolling

public void configurePolling(Graph graph,
                             com.fasterxml.jackson.databind.JsonNode config)
                      throws Exception

Description copied from class: PollingGraphUpdater

Mirrors GraphUpdater.configure method.

Specified by:

configurePolling in class PollingGraphUpdater

Throws:

Exception

setup

public void setup(Graph graph)

Description copied from interface: GraphUpdater

Here the updater can be initialized. If it throws, the updater won't be started (i.e. the run method won't be called). All updaters' setup methods will be run sequentially in a single-threaded manner before updates begin, in order to avoid concurrent reads/writes.

runPolling

public void runPolling()

Repeatedly makes blocking calls to an UpdateStreamer to retrieve new stop time updates, and applies those updates to the graph.

Specified by:

runPolling in class PollingGraphUpdater

teardown

public void teardown()

Description copied from interface: GraphUpdater

Here the updater can clean up after itself.

toString

public String toString()

Overrides:

toString in class Object
