Interface MTransferable

  • All Superinterfaces:
    All Known Implementing Classes:

    public interface MTransferable
    extends Transferable

    The interface of Marvin transferable implementations.

    This interface extends the functionality of the standard Java transferable interface.

    Marvin utilizes the transferable objects to put Molecule objects to the clipboard in various formats, and to retrieve Molecule data back from the clipboard. The Transferable.getTransferData(java.awt.datatransfer.DataFlavor) function is responsible to place the data to the clipboard in a format specified by its DataFlavors and as a Molecule object when importing from clipboard, if the implementation supports the input from clipboard.

    Every implementation should have a name which identifies the MTransferable in the registry. While naming the MTransferable the developer should keep in mind that the name will be displayed in the Copy As dialog window, if the TransferableDescriptor object of the MTransferable in the registry is configured so.

    In the default java clipboard handling there are some native formats which will be registered into the SystemFlavorMap. If any of the DataFlavors supported by the implementation requires a native format to be registered to the SystemFlavorMap, then the implementation should define the registerNativeNames() function which will be called automatically by ClipboardHandler.

        Constant Field Values

        static final int CLIPBOARD_OPERATION_PUT
        Flag that indicates an export operation
        See Also:
        Constant Field Values

        static final int CLIPBOARD_OPERATION_GET
        Flag that indicates an import operation

        Constant Field Values

        static final String CLIPBOARD_ORIGIN_IS_FILE

    • Method Detail

      • setMolecule

        void setMolecule​(Molecule mol)
        Sets the Molecule which will be represented by the transferable.
        mol - the Molecule object that will be exported to the clipboard.
      • setProperties

        void setProperties​(Properties props)
        Sets display properties of the Molecule. This parameter is useful when transferring Molecule images to clipboard, and can be one of, or the union of properties stored in UserSettings , and in the result of MDocument.getGUIPropertyContainer().
        By default only those objects will use this that export image to the clipboard.
        props - the properties
        See Also:
      • registerNativeNames

        void registerNativeNames()
        Registers the Native names supported by the implementation. This has to be done for all native formats which are not supported by default in Java.
        This function will be called from ClipboardHandler before performing the first clipboard operation.
      • isInputAvailable

        boolean isInputAvailable()
        Checks that the implementation supports input from clipboard.
        true if the representation could read a Molecule from Clipboard false otherwise
      • setTransfer

        void setTransfer​(Transferable transfer)
        Sets the Transferable for importing Molecule from that. This method should not be called if the implementation does not support input from clipboard.
        transfer - the Transferable object
