Class FileTransfer


  • public class FileTransfer
    extends ByteArrayTransfer
    The class FileTransfer provides a platform specific mechanism for converting a list of files represented as a java String[] to a platform specific representation of the data and vice versa. Each String in the array contains the absolute path for a single file or directory.

    An example of a java String[] containing a list of files is shown below:

    
         File file1 = new File("C:\temp\file1");
         File file2 = new File("C:\temp\file2");
         String[] fileData = new String[2];
         fileData[0] = file1.getAbsolutePath();
         fileData[1] = file2.getAbsolutePath();

      • javaToNative

        public void javaToNative​(Object object,
                                 TransferData transferData)
        This implementation of javaToNative converts a list of file names represented by a java String[] to a platform specific representation. Each String in the array contains the absolute path for a single file or directory.
        Overrides:
        javaToNative in class ByteArrayTransfer
        Parameters:
        object - a java String[] containing the file names to be converted
        transferData - an empty TransferData object that will be filled in on return with the platform specific format of the data

      • nativeToJava

        public Object nativeToJava​(TransferData transferData)
        This implementation of nativeToJava converts a platform specific representation of a list of file names to a java String[]. Each String in the array contains the absolute path for a single file or directory.
        Overrides:
        nativeToJava in class ByteArrayTransfer
        Parameters:
        transferData - the platform specific representation of the data to be converted
        Returns:
        a java String[] containing a list of file names if the conversion was successful; otherwise null
