-
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();
