getSummary

public java.lang.String getSummary()

Description copied from interface: Summarizable

Implementations are encouraged to return an inline created new Object() whose toString() method will return the actual String instead of just returning the String directly. This helps loggers be more efficient as the String won't be generated until the log level demands it.

getSummary in interface Request

Specified by:

getSummary in interface Summarizable

Overrides:

getSummary in class BasicReconfigurationPacket<NodeIDType>

Returns:

A pretty-print summary.

getMyReceiver

public java.net.InetSocketAddress getMyReceiver()

Returns:

Socket address on which this request was received.

hasDeletedNodes

public boolean hasDeletedNodes()

Returns:

True if deletedNodes has elements.

hasAddedNodes

public boolean hasAddedNodes()

Returns:

True if newlyAddedNodes has elements.
