Interface Cluster

All Known Implementing Classes:

StandardCluster

public interface Cluster

A Cluster works as a Cluster client/server for the local host Different Cluster implementations can be used to support different ways to communicate within the Cluster. A Cluster implementation is responsible for setting up a way to communicate within the Cluster and also supply "ClientApplications" with ClusterSender used when sending information in the Cluster and ClusterInfo used for receiving information in the Cluster.

Method Summary

int	getCheckInterval() Get the time in seconds that this Cluster sleeps.
java.lang.String	getClusterName() Return the name of the cluster that this Server is currently configured to operate within.
ClusterReceiver	getClusterReceiver(java.lang.String senderId) Returns a ClusterReceiver which is the interface to use when receiving information in the Cluster. senderId is used as a indentifier, only information send through the ClusterSender with the same senderId can be received.
ClusterSender	getClusterSender(java.lang.String senderId) Returns a ClusterSender which is the interface to use when sending information in the Cluster. senderId is used as a identifier so that information sent through this instance can only be used with the respectice ClusterReceiver
Container	getContainer() Get the Container associated with our Cluster
int	getDebug() Returns the debug level for this Cluster
java.lang.String	getInfo() Return descriptive information about this Cluster implementation and the corresponding version number, in the format <description>/<version>.
ClusterMemberInfo	getLocalClusterMember() Return cluster information about the local host
ClusterMemberInfo[]	getRemoteClusterMembers() Returns a collection containing ClusterMemberInfo on the remote members of this Cluster.
void	setCheckInterval(int checkInterval) Set the time in seconds that the Cluster waits before checking for changes and replicated data.
void	setClusterName(java.lang.String clusterName) Set the name of the cluster to join, if no cluster with this name is present create one.
void	setContainer(Container container) Set the Container associated with our Cluster
void	setDebug(int debug) The debug detail level for this Cluster

Method Detail

getInfo

public java.lang.String getInfo()

Return descriptive information about this Cluster implementation and the corresponding version number, in the format <description>/<version>.

getClusterName

public java.lang.String getClusterName()

Return the name of the cluster that this Server is currently configured to operate within.

Returns:

The name of the cluster associated with this server

setCheckInterval

public void setCheckInterval(int checkInterval)

Set the time in seconds that the Cluster waits before checking for changes and replicated data.

Parameters:

checkInterval - The time in seconds to sleep

getCheckInterval

public int getCheckInterval()

Get the time in seconds that this Cluster sleeps.

Returns:

The value in seconds

setClusterName

public void setClusterName(java.lang.String clusterName)

Set the name of the cluster to join, if no cluster with this name is present create one.

Parameters:

clusterName - The clustername to join

setContainer

public void setContainer(Container container)

Set the Container associated with our Cluster

Parameters:

container - The Container to use

getContainer

public Container getContainer()

Get the Container associated with our Cluster

Returns:

The Container associated with our Cluster

setDebug

public void setDebug(int debug)

The debug detail level for this Cluster

Parameters:

debug - The debug level

getDebug

public int getDebug()

Returns the debug level for this Cluster

Returns:

The debug level

getRemoteClusterMembers

public ClusterMemberInfo[] getRemoteClusterMembers()

Returns a collection containing ClusterMemberInfo on the remote members of this Cluster. This method does not include the local host, to retrieve ClusterMemberInfo on the local host use getLocalClusterInfo() instead.

Returns:

Collection with all members in the Cluster

getClusterSender

public ClusterSender getClusterSender(java.lang.String senderId)

Returns a ClusterSender which is the interface to use when sending information in the Cluster. senderId is used as a identifier so that information sent through this instance can only be used with the respectice ClusterReceiver

Returns:

The ClusterSender

getClusterReceiver

public ClusterReceiver getClusterReceiver(java.lang.String senderId)

Returns a ClusterReceiver which is the interface to use when receiving information in the Cluster. senderId is used as a indentifier, only information send through the ClusterSender with the same senderId can be received.

Returns:

The ClusterReceiver

getLocalClusterMember

public ClusterMemberInfo getLocalClusterMember()

Return cluster information about the local host

Returns:

Cluster information
