public class SequenceCommand
extends Command

A command consisting of a sequence of other commands. Executes the other commands and undo them in reverse order.

Field Summary

boolean	continueOnError
private java.lang.String	name
private Command[]	sequence The command sequenz to be executed.
private boolean	sequence_complete

Constructor Summary

SequenceCommand(java.lang.String name, java.util.Collection<Command> sequenz)
Create the command by specifying the list of commands to execute.

SequenceCommand(java.lang.String name, Command... sequenz)
Convenient constructor, if the commands are known at compile time.

Method Summary

boolean	executeCommand() Executes the command on the dataset.
void	fillModifiedData(java.util.Collection<OsmPrimitive> modified, java.util.Collection<OsmPrimitive> deleted, java.util.Collection<OsmPrimitive> added) Fill in the changed data this command operates on.
java.util.Collection<PseudoCommand>	getChildren() Returns the subcommands of this command.
javax.swing.Icon	getDescriptionIcon() Provides a descriptive icon of this command.
java.lang.String	getDescriptionText() Provides a description text representing this command.
Command	getLastCommand()
java.util.Collection<? extends OsmPrimitive>	getParticipatingPrimitives() Return the primitives that take part in this command.
void	undoCommand() Undoes the command.
private void	undoCommands(int start)

Constructor Detail

SequenceCommand

public SequenceCommand(java.lang.String name,
                       java.util.Collection<Command> sequenz)

Create the command by specifying the list of commands to execute.

Parameters:

sequenz - The sequence that should be executed.

SequenceCommand

public SequenceCommand(java.lang.String name,
                       Command... sequenz)

Convenient constructor, if the commands are known at compile time.

Method Detail

executeCommand

public boolean executeCommand()

Description copied from class: Command

Executes the command on the dataset. This implementation will remember all primitives returned by fillModifiedData for restoring them on undo.

Overrides:

executeCommand in class Command

getLastCommand

public Command getLastCommand()

undoCommands

private void undoCommands(int start)

undoCommand

public void undoCommand()

Description copied from class: Command

Undoes the command. It can be assumed that all objects are in the same state they were before. It can also be assumed that executeCommand was called exactly once before. This implementation undoes all objects stored by a former call to executeCommand.

Overrides:

undoCommand in class Command

fillModifiedData

public void fillModifiedData(java.util.Collection<OsmPrimitive> modified,
                             java.util.Collection<OsmPrimitive> deleted,
                             java.util.Collection<OsmPrimitive> added)

Description copied from class: Command

Fill in the changed data this command operates on. Add to the lists, don't clear them.

Specified by:

fillModifiedData in class Command

Parameters:

modified - The modified primitives

deleted - The deleted primitives

added - The added primitives

getDescriptionText

public java.lang.String getDescriptionText()

Description copied from class: PseudoCommand

Provides a description text representing this command.

Specified by:

getDescriptionText in class PseudoCommand

getDescriptionIcon

public javax.swing.Icon getDescriptionIcon()

Description copied from class: PseudoCommand

Provides a descriptive icon of this command.

Overrides:

getDescriptionIcon in class PseudoCommand

getChildren

public java.util.Collection<PseudoCommand> getChildren()

Description copied from class: PseudoCommand

Returns the subcommands of this command. Override for subclasses that have child commands.

Overrides:

getChildren in class PseudoCommand

Returns:

the subcommands, null if there are no child commands

getParticipatingPrimitives

public java.util.Collection<? extends OsmPrimitive> getParticipatingPrimitives()

Description copied from class: Command

Return the primitives that take part in this command.

Overrides:

getParticipatingPrimitives in class Command
