Constructor Detail

PurgeCommand

public PurgeCommand(DataSet data,
                    java.util.Collection<OsmPrimitive> toPurge,
                    java.util.Collection<OsmPrimitive> makeIncomplete)

Constructs a new PurgeCommand (does not handle conflicts). This command relies on a number of consistency conditions: - makeIncomplete must be a subset of toPurge. - Each primitive, that is in toPurge but not in makeIncomplete, must have all its referrers in toPurge. - Each element of makeIncomplete must not be new and must have only referrers that are either a relation or included in toPurge.

Parameters:

data - OSM data set

toPurge - primitives to purge

makeIncomplete - primitives to make incomplete

Since:

11240

Method Detail

init

private void init(java.util.Collection<OsmPrimitive> toPurge,
                  java.util.Collection<OsmPrimitive> makeIncomplete)

saveIncomplete

protected final void saveIncomplete(java.util.Collection<OsmPrimitive> makeIncomplete)

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

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

topoSort

public static java.util.List<OsmPrimitive> topoSort(java.util.Collection<OsmPrimitive> sel)

Sorts a collection of primitives such that for each object its referrers come later in the sorted collection.

Parameters:

sel - collection of primitives to sort

Returns:

sorted list

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

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

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

hashCode

public int hashCode()

Overrides:

hashCode in class Command

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class Command

build

public static PurgeCommand build(java.util.Collection<OsmPrimitive> sel,
                                 java.util.List<OsmPrimitive> toPurgeAdditionally)

Creates a new PurgeCommand to purge selected OSM primitives.

Parameters:

sel - selected OSM primitives

toPurgeAdditionally - optional list that will be filled with primitives to be purged that have not been in the selection

Returns:

command to purge selected OSM primitives

Since:

12718

hasOnlyIncompleteMembers

private static boolean hasOnlyIncompleteMembers(Relation r,
                                                java.util.Collection<OsmPrimitive> toPurge,
                                                java.util.Collection<? extends OsmPrimitive> moreToPurge)
