Constructor Detail

AbstractOsmDataPaster

protected AbstractOsmDataPaster(java.awt.datatransfer.DataFlavor df)

Create a new AbstractOsmDataPaster

Parameters:

df - The data flavor that this support supports.

Method Detail

supports

public boolean supports(javax.swing.TransferHandler.TransferSupport support)

Checks if this supports importing the given transfer support.

Parameters:

support - The support that should be supported.

Returns:

True if we support that transfer.

supports

public boolean supports(java.util.Collection<java.awt.datatransfer.DataFlavor> available)

Checks if this supports any of the available flavors.

Parameters:

available - The flavors that should be supported

Returns:

True if any of them is supported.

isCopy

private static boolean isCopy(javax.swing.TransferHandler.TransferSupport support)

importData

public abstract boolean importData(javax.swing.TransferHandler.TransferSupport support,
                                   OsmDataLayer layer,
                                   EastNorth pasteAt)
                            throws java.awt.datatransfer.UnsupportedFlavorException,
                                   java.io.IOException

Attempts to import the given transfer data.

Parameters:

support - The transfer support to import from.

layer - The layer to paste at. May be null.

pasteAt - The position to paste at.

Returns:

true if the import was successful.

Throws:

java.awt.datatransfer.UnsupportedFlavorException - if the requested data flavor is not supported

java.io.IOException - if an I/O error occurs

importTagsOn

public boolean importTagsOn(javax.swing.TransferHandler.TransferSupport support,
                            java.util.Collection<? extends OsmPrimitive> selection)
                     throws java.awt.datatransfer.UnsupportedFlavorException,
                            java.io.IOException

Imports only if this import changes the tags only. Does nothing if more than tags would be changed.

Parameters:

support - The support

selection - The primitives to apply on.

Returns:

true if an import was done.

Throws:

java.awt.datatransfer.UnsupportedFlavorException - if the requested data flavor is not supported

java.io.IOException - if an I/O error occurs
