      • getTransferDataFlavors

        public java.awt.datatransfer.DataFlavor[] getTransferDataFlavors()
        Returns an array of DataFlavor objects indicating the flavors the data can be provided in. The array should be ordered according to preference for providing the data (from most richly descriptive to least descriptive).
        Specified by:
        getTransferDataFlavors in interface java.awt.datatransfer.Transferable
        Returns:
        an array of data flavors in which this data can be transferred
      • isDataFlavorSupported

        public boolean isDataFlavorSupported​(java.awt.datatransfer.DataFlavor flavor)
        Returns whether or not the specified data flavor is supported for this object.
        Specified by:
        isDataFlavorSupported in interface java.awt.datatransfer.Transferable
        Parameters:
        flavor - the requested flavor for the data
        Returns:
        boolean indicating whether or not the data flavor is supported
      • getTransferData

        public java.lang.Object getTransferData​(java.awt.datatransfer.DataFlavor flavor)
                                         throws java.awt.datatransfer.UnsupportedFlavorException,
                                                java.io.IOException
        Returns an object which represents the data to be transferred. The class of the object returned is defined by the representation class of the flavor.
        Specified by:
        getTransferData in interface java.awt.datatransfer.Transferable
        Parameters:
        flavor - the requested flavor for the data
        Throws:
        java.io.IOException - if the data is no longer available in the requested flavor.
        java.awt.datatransfer.UnsupportedFlavorException - if the requested data flavor is not supported.
