Constructor Detail

ImageSelection

public ImageSelection(java.awt.image.BufferedImage data)

Creates a Transferable capable of transferring the specified String.

Method Detail

getTransferDataFlavors

public java.awt.datatransfer.DataFlavor[] getTransferDataFlavors()

Returns an array of flavors in which this Transferable can provide the data. DataFlavor.stringFlavor is properly supported. Support for DataFlavor.plainTextFlavor is deprecated.

Specified by:

getTransferDataFlavors in interface java.awt.datatransfer.Transferable

Returns:

an array of length two, whose elements are DataFlavor. stringFlavor and DataFlavor.plainTextFlavor.

isDataFlavorSupported

public boolean isDataFlavorSupported(java.awt.datatransfer.DataFlavor flavor)

Returns whether the requested flavor is supported by this Transferable.

Specified by:

isDataFlavorSupported in interface java.awt.datatransfer.Transferable

Parameters:

flavor - the requested flavor for the data

Returns:

true if flavor is equal to DataFlavor.stringFlavor or DataFlavor.plainTextFlavor; false if flavor is not one of the above flavors

Throws:

java.lang.NullPointerException - if flavor is null

getTransferData

public java.lang.Object getTransferData(java.awt.datatransfer.DataFlavor flavor)
                                 throws java.awt.datatransfer.UnsupportedFlavorException,
                                        java.io.IOException

Returns the Transferable's data in the requested DataFlavor if possible. If the desired flavor is DataFlavor.stringFlavor, or an equivalent flavor, the String representing the selection is returned. If the desired flavor is DataFlavor.plainTextFlavor , or an equivalent flavor, a Reader is returned. Note: The behavior of this method for DataFlavor.plainTextFlavor and equivalent DataFlavors is inconsistent with the definition of DataFlavor.plainTextFlavor.

Specified by:

getTransferData in interface java.awt.datatransfer.Transferable

Parameters:

flavor - the requested flavor for the data

Returns:

the data in the requested flavor, as outlined above.

Throws:

java.awt.datatransfer.UnsupportedFlavorException - if the requested data flavor is not equivalent to either DataFlavor.stringFlavor or DataFlavor.plainTextFlavor.

java.io.IOException - if an IOException occurs while retrieving the data. By default, StringSelection never throws this exception, but a subclass may.

java.lang.NullPointerException - if flavor is null
