Class WorkspaceMigrator

java.lang.Object
oracle.ide.migration.NodeMigrator
oracle.ide.model.WorkspaceMigrator

public class WorkspaceMigrator

extends NodeMigrator

Workspace migrator. To lookup this migrator use the method NodeMigrator.getNodeMigrator(java.lang.String) specifying the name identifier: MIGRATOR_NAME. Migrator helpers registered with the WorkspaceMigrator will execute before migrator helpers registered with ProjectMigrator.

Field Summary

static java.lang.String	MIGRATOR_NAME String identifier used to lookup a specific node migrator.
static java.lang.String	WORKSPACE_NODE String identifier used to lookup the workspace node from a given TraversableContext.

Field Detail

MIGRATOR_NAME

public static final java.lang.String MIGRATOR_NAME

String identifier used to lookup a specific node migrator. This particular constant identifies the workspace migrator. Migrator name identifiers must be the class name of the node the migrator migrates.

WORKSPACE_NODE

public static final java.lang.String WORKSPACE_NODE

String identifier used to lookup the workspace node from a given TraversableContext. Project migrators that need to find out the workspace triggering migration can use this constant to find the workspace. If the TraversableContext.get(WORKSPACE_NODE) method returns a null value, it generally implies that the project is being migrated directly, without the workspace. This can happen when a user opens a project in the context of a workspace already opened in the navigator.

Method Detail

getPages

public java.util.List getPages(MigrationInfo[] infos,
                               TraversableContext context)

Description copied from class: NodeMigrator

Get the list of wizard pages associated with the specified infos. Clients must use the context object to store the data diplayed in these pages.

Overrides:

getPages in class NodeMigrator

Parameters:

infos - migration information about the nodes to migrate. All nodes must be of the same type.

context - use the context to store the data gathered from the pages.

Returns:

a list of migration pages that the migration wizard displays.

preMigrate

protected final void preMigrate(MigrationInfo[] infos,
                                TraversableContext context)

Description copied from class: NodeMigrator

Method called before migration is initiated. This method should be overriden if a migrator implementation needs to setup before migration starts. The default implementation does nothing.

Overrides:

preMigrate in class NodeMigrator

Parameters:

infos - information about the nodes that may require migration. All nodes held in the MigrationInfo must be of the same type.

context - contains a Map that can be obtained from the context using the name identifier: NodeMigrator.MIGRATOR_MAP_DATA. The information needed to do the migration is held by this map.

postMigrate

protected final void postMigrate(MigrationInfo[] infos,
                                 TraversableContext context)

Description copied from class: NodeMigrator

Method called after migration is complete. The default implementation does nothing.

Overrides:

postMigrate in class NodeMigrator

Parameters:

infos - information about the nodes that may require migration. All nodes held in the MigrationInfo must be of the same type.

context - contains addin specific migration data that is passed on to the helpers such that they can use that information when migrating their data.

getMsg

protected java.lang.String getMsg(MigrationInfo[] infos)

Description copied from class: NodeMigrator

Get the wizard welcome page message. Subclasses must implement this method to define the welcome page message.

Specified by:

getMsg in class NodeMigrator

Returns:

the welcome page message.

getTitle

protected java.lang.String getTitle()

Description copied from class: NodeMigrator

Get the wizard title. Subclasses must implement this method to define the wizard title.

Specified by:

getTitle in class NodeMigrator

Returns:

the wizard title.

getSummaryMsg

protected java.lang.String getSummaryMsg(MigrationInfo[] infos)

Description copied from class: NodeMigrator

Get the message for the wizard summary page. Subclasses must implement this method to define the summary page message.

Specified by:

getSummaryMsg in class NodeMigrator

Returns:

the summary page message.

getWeight

protected float getWeight()

Description copied from class: NodeMigrator

Returns the weight which we wish to give to the migrator when migrating it.

Overrides:

getWeight in class NodeMigrator

Returns:

a value in [0.00, 1.00] range. Lower values means "execute earlier". e.g. 0.00 means try to be the first, 1.00 means execute at the mercy of the migration scheduler.

getMigrationInfo

public MigrationInfo getMigrationInfo(Node node)

Description copied from class: NodeMigrator

Get the current MigrationInfo for the specified node.

Specified by:

getMigrationInfo in class NodeMigrator

Parameters:

node - the target node for which migration information is being requested.

getHelpers

protected NodeMigratorHelper[] getHelpers(MigrationInfo info)

Description copied from class: NodeMigrator

Get the NodeMigratorHelpers that are newer than the version number stored in the project file.

Overrides:

getHelpers in class NodeMigrator
