Constructor Details

RACKSPACE_PING

public RACKSPACE_PING()

Method Details

init

public void init()
          throws Exception

Description copied from class: Protocol

Called after a protocol has been created and before the protocol is started. Attributes are already set. Other protocols are not yet connected and events cannot yet be sent.

Specified by:

init in interface Lifecycle

Overrides:

init in class FILE_PING

Throws:

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

createRootDir

protected void createRootDir()

Overrides:

createRootDir in class FILE_PING

readAll

protected void readAll(List<Address> members,
 String clustername,
 Responses responses)

Overrides:

readAll in class FILE_PING

write

protected void write(List<PingData> list,
 String clustername)

Overrides:

write in class FILE_PING

remove

protected void remove(String clustername,
 Address addr)

Overrides:

remove in class FILE_PING

removeAll

protected void removeAll(String clustername)

Description copied from class: FILE_PING

Removes all files for the given cluster name

Overrides:

removeAll in class FILE_PING
