Method Detail

getBackupGroupName

String getBackupGroupName()

Returns the backup-group-name of the live server and backup servers associated with Topology entry.

This is a server configuration value. A (remote) backup will only work with live servers that have a matching backup-group-name.

This value does not apply to "shared-storage" backup and live pairs.

Returns:

the backup-group-name

getScaleDownGroupName

String getScaleDownGroupName()

Returns the scale-down-group-name of the live server with this Topology entry.

This is a server configuration value. a live server will only send its messages to another live server with matching scale-down-group-name.

Returns:

the scale-down-group-name

getLive

TransportConfiguration getLive()

Returns:

configuration relative to the live server

getBackup

TransportConfiguration getBackup()

Returns the TransportConfiguration relative to the backup server if any.

Returns:

a TransportConfiguration for the backup, or null} if the live server has no backup server.

getNodeId

String getNodeId()

Returns the nodeId of the server.

Returns:

the nodeId

getUniqueEventID

long getUniqueEventID()

Returns:

long value representing a unique event ID

isMember

boolean isMember(RemotingConnection connection)

Returns true if this TopologyMember is the target of this remoting connection

Parameters:

connection -

Returns:

isMember

boolean isMember(TransportConfiguration configuration)

Returns true if this configuration is the target of this remoting connection

Parameters:

configuration -

Returns:

toURI

String toURI()
