Constructor Detail

RestoreHistoryCommand

public RestoreHistoryCommand()

Method Detail

getName

public java.lang.String getName()

Description copied from class: Command

Gets the name of the command to display as the action to undo

Specified by:

getName in interface HistoryGeneratingCommand

Overrides:

getName in class Command

doit

public int doit()
         throws java.lang.Exception

Description copied from class: RevertNodeCommand

Executes the actions associated with the revert command to revert the specified node.

Overrides:

doit in class RevertNodeCommand

Returns:

Command.OK if the reload was successful, otherwise Command.CANCEL

Throws:

java.lang.Exception

getHistoriedNodes

public Node[] getHistoriedNodes()

Description copied from interface: HistoryGeneratingCommand

Get an array of Node whose state should be persisted.

Specified by:

getHistoriedNodes in interface HistoryGeneratingCommand

Returns:

an array of Node.

isGeneratePrecedingState

public boolean isGeneratePrecedingState()

Description copied from interface: HistoryGeneratingCommand

Determine whether or not the state preceding the invokation of the Command should also be generated if a historied Node is found to be dirty.

Generally speaking, implementations should not have to exercise any conditions; Either a preceding state should always be generated (e.g. a refactoring Command), or never generated (e.g. a Save command). The result of this method will only be considered if a historied Node was first found to be dirty before the invokation of the Command.

Commands of type MULTI_DOCUMENT are always treated as HistoryGeneratingCommands and thus need not implement this interface.

Specified by:

isGeneratePrecedingState in interface HistoryGeneratingCommand

Returns:

true if the preceding state should also be generated.
