Constructor Detail

MergeLayerAction

public MergeLayerAction()

Constructs a new MergeLayerAction.

Method Detail

doMerge

protected java.util.concurrent.Future<?> doMerge(java.util.List<? extends Layer> targetLayers,
                                                 java.util.Collection<? extends Layer> sourceLayers)

Submits merge of layers.

Parameters:

targetLayers - possible target layers

sourceLayers - source layers

Returns:

a Future representing pending completion of the merge task, or null

Since:

11885 (return type)

merge

public java.util.concurrent.Future<?> merge(java.util.List<? extends Layer> sourceLayers)

Merges a list of layers together.

Parameters:

sourceLayers - The layers to merge

Returns:

a Future representing pending completion of the merge task, or null

Since:

11885 (return type)

merge

public java.util.concurrent.Future<?> merge(Layer sourceLayer)

Merges the given source layer with another one, determined at runtime.

Parameters:

sourceLayer - The source layer to merge

Returns:

a Future representing pending completion of the merge task, or null

Since:

11885 (return type)

actionPerformed

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

listenToSelectionChange

protected boolean listenToSelectionChange()

Description copied from class: JosmAction

Overwrite this if JosmAction.updateEnabledState() should be called when the selection changed. Default is true.

Overrides:

listenToSelectionChange in class JosmAction

Returns:

true if a DataSelectionListener should be registered.

updateEnabledState

protected void updateEnabledState()

Description copied from class: JosmAction

Override in subclasses to update the enabled state of the action when something in the JOSM state changes, i.e. when a layer is removed or added. See JosmAction.updateEnabledState(Collection) to respond to changes in the collection of selected primitives. Default behavior is empty.

Overrides:

updateEnabledState in class JosmAction

See Also:

JosmAction.updateEnabledState(Collection), JosmAction.initEnabledState(), JosmAction.listenToLayerChange()

getSourceLayer

protected Layer getSourceLayer()

Returns the source layer.

Returns:

the source layer

warnMergingUploadDiscouragedLayers

public static final boolean warnMergingUploadDiscouragedLayers(Layer sourceLayer,
                                                               Layer targetLayer)

Warns about a discouraged merge operation, ask for confirmation.

Parameters:

sourceLayer - The source layer

targetLayer - The target layer

Returns:

true if the user wants to cancel, false if they want to continue
