Method Detail

name

public java.lang.String name()

Description copied from interface: Manager

The unique identify name.

Specified by:

name in interface Manager

init

public void init(org.apache.hugegraph.computer.core.config.Config config)

Description copied from interface: Manager

Used to add the resources needed by the computation. Be called only one time before all supersteps start.

Specified by:

init in interface Manager

beforeSuperstep

public void beforeSuperstep(org.apache.hugegraph.computer.core.config.Config config,
                            int superstep)

Description copied from interface: Manager

Do some initialization for a superstep. Be called before a superstep. Subclass should override this method if wants to do something before a superstep.

Specified by:

beforeSuperstep in interface Manager

afterSuperstep

public void afterSuperstep(org.apache.hugegraph.computer.core.config.Config config,
                           int superstep)

Description copied from interface: Manager

Do some clean up for a superstep. Be called after a superstep. Subclass should override this method if wants to do something after a superstep.

Specified by:

afterSuperstep in interface Manager

onChannelActive

public void onChannelActive(ConnectionId connectionId)

Description copied from interface: TransportHandler

Invoked when the channel associated with the given connectionId is active.

Specified by:

onChannelActive in interface TransportHandler

onChannelInactive

public void onChannelInactive(ConnectionId connectionId)

Description copied from interface: TransportHandler

Invoked when the channel associated with the given connectionId is inactive. No further requests will come from this channel.

Specified by:

onChannelInactive in interface TransportHandler

exceptionCaught

public void exceptionCaught(TransportException cause,
                            ConnectionId connectionId)
