public class CreateMultipolygonAction
extends JosmAction

Create multipolygon from selected ways automatically. New relation with type=multipolygon is created. If one or more of ways is already in relation with type=multipolygon or the way is not closed, then error is reported and no relation is created. The "inner" and "outer" roles are guessed automatically. First, bbox is calculated for each way. then the largest area is assumed to be outside and the rest inside. In cases with one "outside" area and several cut-ins, the guess should be always good ... In more complex (multiple outer areas) or buggy (inner and outer ways intersect) scenarios the result is likely to be wrong.

Constructor Detail

CreateMultipolygonAction

public CreateMultipolygonAction(boolean update)

Constructs a new CreateMultipolygonAction.

Parameters:

update - true if the multipolygon must be updated, false if it must be created

Method Detail

getName

private static java.lang.String getName(boolean update)

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

getSelectedMultipolygonRelation

private static Relation getSelectedMultipolygonRelation(java.util.Collection<Way> selectedWays,
                                                        java.util.Collection<Relation> selectedRelations)

updateMultipolygonRelation

public static Pair<Relation,Relation> updateMultipolygonRelation(java.util.Collection<Way> selectedWays,
                                                                       Relation selectedMultipolygonRelation)

Returns a Pair of the old multipolygon Relation (or null) and the newly created/modified multipolygon Relation.

Parameters:

selectedWays - selected ways

selectedMultipolygonRelation - selected multipolygon relation

Returns:

null if ways don't build a valid multipolygon, pair of old and new multipolygon relation if a difference was found, else the pair contains the old relation twice

mergeRelationsMembers

private static Pair<Relation,Relation> mergeRelationsMembers(Relation old,
                                                                   Relation calculated)

Merge members of multipolygon relation. Maintains the order of the old relation. May change roles, removes duplicate and non-way members and adds new members found in calculated.

Parameters:

old - old multipolygon relation

calculated - calculated multipolygon relation

Returns:

pair of old and new multipolygon relation if a difference was found, else the pair contains the old relation twice

createMultipolygonRelation

public static Pair<Relation,Relation> createMultipolygonRelation(java.util.Collection<Way> selectedWays,
                                                                       boolean showNotif)

Returns a Pair null and the newly created/modified multipolygon Relation.

Parameters:

selectedWays - selected ways

showNotif - if true, shows a notification if an error occurs

Returns:

pair of null and new multipolygon relation

showErrors

private static void showErrors(java.util.List<TestError> errors)

createMultipolygonCommand

Parameters:

selectedWays - selected ways

selectedMultipolygonRelation - selected multipolygon relation

Returns:

pair of command and multipolygon relation

updateEnabledState

protected void updateEnabledState()

removeTagsFromWaysIfNeeded
