public class FileTransfer extends ByteArrayTransfer
The classFileTransfer
provides a platform specific mechanism for converting a list of files represented as a javaString[]
to a platform specific representation of the data and vice versa. EachString
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();
