Constructor Detail

SWIFT_PING

public SWIFT_PING()

Method Detail

init

public void init()
          throws java.lang.Exception

Description copied from class: Protocol

Called after instance has been created (null constructor) and before protocol is started. Properties are already set. Other protocols are not yet connected and events cannot yet be sent.

Overrides:

init in class FILE_PING

Throws:

java.lang.Exception - Thrown if protocol cannot be initialized successfully. This will cause the ProtocolStack to fail, so the channel constructor will throw an exception

remove

protected void remove(java.lang.String clustername,
                      Address addr)

Overrides:

remove in class FILE_PING

readAll

protected java.util.List<PingData> readAll(java.lang.String clustername)

Description copied from class: FILE_PING

Reads all information from the given directory under clustername

Overrides:

readAll in class FILE_PING

Returns:

writeToFile

protected void writeToFile(PingData data,
                           java.lang.String clustername)

Overrides:

writeToFile in class FILE_PING

createRootDir

protected void createRootDir()

Overrides:

createRootDir in class FILE_PING
