public StringSelection(String data) 
{
                  
        this.data = data;
}

Creates a Transferable capable of transferring the specified String.

 public Object getTransferData(DataFlavor flavor) throws IOException, UnsupportedFlavorException 
{
        // JCK Test StringSelection0007: if 'flavor' is null, throw NPE
        if (flavor.equals(flavors[STRING])) {
            return (Object)data;
        } else if (flavor.equals(flavors[PLAIN_TEXT])) {
            return new StringReader(data == null ? "" : data);
        } else {
            throw new UnsupportedFlavorException(flavor);
        }
}

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.

 public DataFlavor[] getTransferDataFlavors() 
{
        // returning flavors itself would allow client code to modify
        // our internal behavior
        return (DataFlavor[])flavors.clone();
}

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

 public boolean isDataFlavorSupported(DataFlavor flavor) 
{
        // JCK Test StringSelection0003: if 'flavor' is null, throw NPE
        for (int i = 0; i <  flavors.length; i++) {
            if (flavor.equals(flavors[i])) {
                return true;
            }
        }
        return false;
}

Returns whether the requested flavor is supported by this Transferable.
