Field Detail

noteData

private final NoteData noteData

Constructor Detail

NoteLayer

public NoteLayer(java.util.List<Note> notes,
                 java.lang.String name)

Create a new note layer with a set of notes

Parameters:

notes - A list of notes to show in this layer

name - The name of the layer. Typically "Notes"

NoteLayer

public NoteLayer()

Convenience constructor that creates a layer with an empty note list

Method Detail

hookUpMapView

public void hookUpMapView()

Description copied from class: Layer

Initialization code, that depends on Main.map.mapView. It is always called in the event dispatching thread. Note that Main.map is null as long as no layer has been added, so do not execute code in the constructor, that assumes Main.map.mapView is not null. Instead override this method.

Overrides:

hookUpMapView in class Layer

getNoteData

public NoteData getNoteData()

Returns the note data store being used by this layer

Returns:

noteData containing layer notes

isModified

public boolean isModified()

Description copied from class: AbstractModifiableLayer

Determines if data managed by this layer has been modified.

Specified by:

isModified in class AbstractModifiableLayer

Returns:

true if data has been modified; false, otherwise

requiresUploadToServer

public boolean requiresUploadToServer()

Description copied from class: AbstractModifiableLayer

Determines if the data managed by this layer needs to be uploaded to the server because it contains modified data.

Overrides:

requiresUploadToServer in class AbstractModifiableLayer

Returns:

true if the data managed by this layer needs to be uploaded to the server because it contains modified data; false, otherwise

isSavable

public boolean isSavable()

Description copied from class: Layer

Replies the savable state of this layer (i.e if it can be saved through a "File->Save" dialog).

Overrides:

isSavable in class Layer

Returns:

true if this layer can be saved to a file

requiresSaveToFile

public boolean requiresSaveToFile()

Description copied from class: AbstractModifiableLayer

Determines if the data managed by this layer needs to be saved to a file. Only replies true if a file is assigned to this layer and if the data managed by this layer has been modified since the last save operation to the file.

Overrides:

requiresSaveToFile in class AbstractModifiableLayer

Returns:

true if the data managed by this layer needs to be saved to a file

paint

public void paint(java.awt.Graphics2D g,
                  MapView mv,
                  Bounds box)

Description copied from class: Layer

Paint the dataset using the engine set.

Specified by:

paint in interface MapViewPaintable

Specified by:

paint in class Layer

mv - The object that can translate GeoPoints to screen coordinates.

getIcon

public javax.swing.Icon getIcon()

Description copied from class: Layer

Return a representative small image for this layer. The image must not be larger than 64 pixel in any dimension.

Specified by:

getIcon in class Layer

getToolTipText

public java.lang.String getToolTipText()

Specified by:

getToolTipText in class Layer

Returns:

A small tooltip hint about some statistics for this layer.

mergeFrom

public void mergeFrom(Layer from)

Description copied from class: Layer

Merges the given layer into this layer. Throws if the layer types are incompatible.

Specified by:

mergeFrom in class Layer

Parameters:

from - The layer that get merged into this one. After the merge, the other layer is not usable anymore and passing to one others mergeFrom should be one of the last things to do with a layer.

isMergable

public boolean isMergable(Layer other)

Specified by:

isMergable in class Layer

Parameters:

other - The other layer that is tested to be mergable with this.

Returns:

Whether the other layer can be merged into this layer.

visitBoundingBox

public void visitBoundingBox(BoundingXYVisitor v)

Specified by:

visitBoundingBox in class Layer

getInfoComponent

public java.lang.Object getInfoComponent()

Specified by:

getInfoComponent in class Layer

getMenuEntries

public javax.swing.Action[] getMenuEntries()

Description copied from class: Layer

Returns list of actions. Action can implement LayerAction interface when it needs to be represented by other menu component than JMenuItem or when it supports multiple layers. Actions that support multiple layers should also have correct equals implementation. Use SeparatorLayerAction.INSTANCE instead of new JSeparator

Specified by:

getMenuEntries in class Layer

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)

Specified by:

mouseClicked in interface java.awt.event.MouseListener

createAndOpenSaveFileChooser

public java.io.File createAndOpenSaveFileChooser()
