Class TextTransfer

          extended by org.eclipse.swt.dnd.TextTransfer

public class TextTransfer
extends ByteArrayTransfer

The class TextTransfer provides a platform specific mechanism for converting plain text represented as a java String to a platform specific representation of the data and vice versa.

An example of a java String containing plain text is shown below:

     String textData = "Hello World";
 

Note the TextTransfer does not change the content of the text data. For a better integration with the platform, the application should convert the line delimiters used in the text data to the standard line delimiter used by the platform.
