public TaskGraphManager()

Method Detail

initTaskGraphManager

public static void initTaskGraphManager(TrianaProperties props)

Initializes the taskgraph factories

initToolTable

public static void initToolTable(ToolTable tools)

Initializes the tool table. This method must be called only once, when the application is first initialized.

getToolTable

public static ToolTable getToolTable()

Returns:

the tool table

addTaskgraphManagerListener

public void addTaskgraphManagerListener(TaskGraphManagerListener listener)

Adds a TaskgraphManagerListener

removeTaskgraphManagerListener

public void removeTaskgraphManagerListener(TaskGraphManagerListener listener)

Adds a TaskgraphManagerListener

registerTaskGraphFactory

public static void registerTaskGraphFactory(java.lang.String type,
                            TaskGraphFactory factory)

Registers a taskgraph factory for the specifed factory type

unregisterTaskGraphFactory

public static void unregisterTaskGraphFactory(java.lang.String type)

Registers the taskgraph factory for the specifed factory type

getTaskGraphFactory

public static TaskGraphFactory getTaskGraphFactory(java.lang.String type)

Returns:

the taskgraph factory for the specified type

isTaskGraphFactory

public static boolean isTaskGraphFactory(java.lang.String type)

Returns:

true if there is taskgraph factory for the specified type

getTrianaServer

public static TrianaServer getTrianaServer(TaskGraph taskgraph)

Returns:

the TrianaServer for the specified TaskGraph

setTrianaServer

public static void setTrianaServer(TaskGraph taskgraph,
                   TrianaServer server)

Sets the TrianaServer for the specified TaskGraph

registerFactoryType

public static void registerFactoryType(Tool tool,
                       java.lang.String type)

Initializes the factory type for the specified tool/taskgraph

getTaskGraphFactoryType

public static java.lang.String getTaskGraphFactoryType(Tool tool)

Returns:

the factory type for the specfied tool. If not type is initialized then the type for its parent (or parent's parent etc.) is returned. (null if not type initialized)

getTaskGraphFactory

public static TaskGraphFactory getTaskGraphFactory(Tool tool)

Returns:

the taskgraph factory for the specified tool.

createTask

public static Task createTask(Tool tool,
              java.lang.String factorytype,
              boolean preserveinst)
                       throws TaskException

Returns:

a new root task/taskgraph instantiated with the specified factory type

Throws:

TaskException

createTaskGraph

public static TaskGraph createTaskGraph()
                                 throws TaskException
