Constructor Detail

ClusterPlatform

public ClusterPlatform()
                throws AbortServiceException

Creates a new ClusterPlatform.

Throws:

AbortServiceException - If the platform has already been bootstrapped or the initialisation or starting of the registry fails, an AbortServiceException will be thrown.

See Also:

AristaFlowPlatform.AristaFlowPlatform()

ClusterPlatform

public ClusterPlatform(ConfigurationPropertyProvider provider)
                throws AbortServiceException

Creates a new ClusterPlatform.

Parameters:

provider - The provider for the global properties including the configuration directories to load additional configurations for the root configuration from. This must not be null.

Throws:

AbortServiceException - If the platform has already been bootstrapped or the initialisation or starting of the registry fails, an AbortServiceException will be thrown.

See Also:

AristaFlowPlatform.AristaFlowPlatform(ConfigurationPropertyProvider)

ClusterPlatform

public ClusterPlatform(Configuration conf)
                throws AbortServiceException

Creates a new ClusterPlatform.

Parameters:

conf - The configuration provided when bootstrapping. This may either be a complete root configuration (without additional configuration directories), a delta configuration complementing or overriding the configurations from the configuration directories or even null. If this is null, only configurations from the configuration directories will be used but this requires a valid rootConfFileName.

Throws:

AbortServiceException - If the platform has already been bootstrapped or the initialisation or starting of the registry fails, an AbortServiceException will be thrown.

AristaFlowPlatform.AristaFlowPlatform(Configuration)

ClusterPlatform

public ClusterPlatform(Configuration conf,
                       ConfigurationPropertyProvider provider)
                throws AbortServiceException

Creates a new ClusterPlatform.

Parameters:

conf - The configuration provided when bootstrapping. This may either be a complete root configuration (without additional configuration directories), a delta configuration complementing or overriding the configurations from the configuration directories or even null. If this is null, only configurations from the configuration directories will be used but this requires a valid rootConfFileName.

provider - The provider for the global properties including the configuration directories to load additional configurations for the root configuration from. This must not be null.

Throws:

AbortServiceException - If the platform has already been bootstrapped or the initialisation or starting of the registry fails, an AbortServiceException will be thrown.

Method Detail

getClusterName

public java.lang.String getClusterName()

Gets the name of the cluster the node of this platform is part of.

Returns:

The name of the cluster the node of this platform is part of.

globalRegistryChanged

protected GlobalRegistry globalRegistryChanged(SessionToken session,
                                               java.net.URI globRegUri)
                                        throws ServiceNotKnownException

Description copied from class: TwoPhasePlatform

Notifies the bootstrap registry that the URI of the global registry has changed to the designated URI. This allows for changing the global registry (usually due to the server in a cluster node) while the platform keeps on running.

Overrides:

globalRegistryChanged in class TwoPhasePlatform<JDBCDataSource>

Parameters:

session - The session which is used to check for access rights on this method.

globRegUri - The new URI of the global registry.

Returns:

The default instance of the global registry with the designated new URI.

Throws:

ServiceNotKnownException - If the default instance of the global registry cannot be retrieved with the new URI, a ServiceNotKnownException will be thrown.
