Field Detail

newSelection

private final java.util.Collection<OsmPrimitive> newSelection

the primitives to select when executing the command

oldSelection

private java.util.Collection<OsmPrimitive> oldSelection

the selection before applying the new selection

Constructor Detail

SelectCommand

public SelectCommand(DataSet dataset,
                     java.util.Collection<OsmPrimitive> newSelection)

Constructs a new select command.

Parameters:

dataset - The dataset the selection belongs to

newSelection - the primitives to select when executing the command.

Since:

12349

Method Detail

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

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

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.

The layer should be invalidated after execution so that it can be re-painted.

Overrides:

executeCommand in class Command

Returns:

true

getParticipatingPrimitives

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

Description copied from class: Command

Return the primitives that take part in this command. The collection is computed during execution.

Specified by:

getParticipatingPrimitives in interface PseudoCommand

Overrides:

getParticipatingPrimitives in class Command

Returns:

primitives that take part in this command

getDescriptionText

public java.lang.String getDescriptionText()

Description copied from interface: PseudoCommand

Provides a description text representing this command.

Returns:

description text representing this command

hashCode

public int hashCode()

Overrides:

hashCode in class Command

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class Command
