Class FileTransfer

java.lang.Object
  org.eclipse.swt.dnd.Transfer
      org.eclipse.swt.dnd.ByteArrayTransfer
          org.eclipse.swt.dnd.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. See Transfer for additional information.

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();
 

Method Summary

static FileTransfer	getInstance() Returns the singleton instance of the FileTransfer class.
protected int[]	getTypeIds() Returns the platform specfic ids of the data types that can be converted using this transfer agent.
protected String[]	getTypeNames() Returns the platform specfic names of the data types that can be converted using this transfer agent.
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.
Object	nativeToJava(TransferData transferData) This implementation of nativeToJava converts a platform specific representation of a list of file names to a java String[].

getInstance

public static FileTransfer getInstance()

Returns the singleton instance of the FileTransfer class.

Returns:

the singleton instance of the FileTransfer class

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. For additional information see Transfer#javaToNative.

Overrides:

javaToNative in class ByteArrayTransfer

Parameters:

object - a java String[] containing the file names to be converted

transferData - an empty TransferData object; this object will be filled in on return with the platform specific format of the data

See Also:

Transfer.javaToNative(java.lang.Object, org.eclipse.swt.dnd.TransferData)

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. For additional information see Transfer#nativeToJava.

Overrides:

nativeToJava in class ByteArrayTransfer

Parameters:

transferData - the platform specific representation of the data to be been converted

Returns:

a java String[] containing a list of file names if the conversion was successful; otherwise null

See Also:

Transfer.nativeToJava(org.eclipse.swt.dnd.TransferData)
