Method Detail

reloadBlocking

public static void reloadBlocking(Dispatcher dispatcher,
                                  com.google.web.bindery.event.shared.EventBus eventBus,
                                  Operation operation,
                                  String type,
                                  String name,
                                  String urlConsole,
                                  Resources resources)

Show a blocking verification dialog and executes the specified operation.

topology

public static List<Task<FlowContext>> topology(Environment environment,
                                               Dispatcher dispatcher)

Returns a list of tasks to read the basic topology. This only includes hosts and server groups, but no servers. Servers are read in a second step to make the whole process more resilient.

The context is populated with the following keys:

• HOSTS: The ordered list of hosts with the domain controller as first element. Each host contains its servers.
• SERVER_GROUPS: The ordered list of server groups. Each server group contains its servers.

hosts

public static List<Task<FlowContext>> hosts(Environment environment,
                                            Dispatcher dispatcher)

Returns a list of tasks to read all hosts (connected and disconnected) and its servers.

The context is populated with the following keys:

• HOSTS: The ordered list of hosts with the domain controller as first element. Each host contains its servers.

Started servers contain additional attributes and optional server boot errors.

serverGroups

public static List<Task<FlowContext>> serverGroups(Environment environment,
                                                   Dispatcher dispatcher)

Returns a list of tasks to read all server groups and its servers.

The context is populated with the following keys:

• SERVER_GROUPS: The ordered list of server groups. Each server group contains its servers.

Started servers contain additional attributes and optional server boot errors.

serverConfigsOfHost

public static List<Task<FlowContext>> serverConfigsOfHost(Environment environment,
                                                          Dispatcher dispatcher,
                                                          String host)

Returns a list of tasks to read the server configs of one host.

The context is populated with the following keys:

• SERVERS: The list of server configs of one host.

serversOfHost

public static List<Task<FlowContext>> serversOfHost(Environment environment,
                                                    Dispatcher dispatcher,
                                                    String host)

Returns a list of tasks to read the servers of one host.

The context is populated with the following keys:

• SERVERS: The list of server configs of one host.

serversOfServerGroup

public static List<Task<FlowContext>> serversOfServerGroup(Environment environment,
                                                           Dispatcher dispatcher,
                                                           String serverGroup)

Returns a list of tasks to read the servers of one server group.

The context is populated with the following keys:

• SERVERS: The list of servers of one server group.

Started servers contain additional attributes and optional server boot errors.

runningServers

public static List<Task<FlowContext>> runningServers(Environment environment,
                                                     Dispatcher dispatcher,
                                                     ModelNode query)

Returns a list of tasks to read all running servers in the domain, which satisfy the specified query.

The context is populated with the following keys:

• SERVERS: The list of running servers with additional attributes and optional server boot errors for started servers.

startedServerOperations

public static Map<String,Composite> startedServerOperations(List<Server> serverConfigs)
