                     OsmPrimitive newOsm)

Constructs a new ChangeCommand in the context of osm data set.

Parameters:

osm - The existing primitive to modify. It must belong to a data set

newOsm - The new primitive

ChangeCommand

public ChangeCommand(DataSet data,
                     OsmPrimitive osm,
                     OsmPrimitive newOsm)

Constructs a new ChangeCommand in the context of a given data set.

Parameters:

data - The data set

osm - The existing primitive to modify

newOsm - The new primitive

Since:

11240

Method Detail

sanityChecks

private void sanityChecks()

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

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 interface: PseudoCommand

Provides a description text representing this command.

Returns:

description text representing this command

getDescriptionIcon

public javax.swing.Icon getDescriptionIcon()

Description copied from interface: PseudoCommand

Provides a descriptive icon of this command.

Returns:

descriptive icon of this command

getOsmPrimitive

public final OsmPrimitive getOsmPrimitive()

Returns the original OSM primitive to modify. It belongs to a dataset.

Returns:

the original OSM primitive to modify

Since:

14283

getNewOsmPrimitive

public final OsmPrimitive getNewOsmPrimitive()

Returns the new OSM primitive.

Returns:

the new OSM primitive

Since:

14283

hashCode

public int hashCode()

Overrides:

hashCode in class Command

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class Command
