public class TextTransfer extends ByteArrayTransfer
The classTextTransfer
provides a platform specific mechanism for converting plain text represented as a javaString
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.- See Also:
