Interface EncodingAware


  • public interface EncodingAware
    A DataSource that also implements EncodingAware may specify the Content-Transfer-Encoding to use for its data. Valid Content-Transfer-Encoding values specified by RFC 2045 are "7bit", "8bit", "quoted-printable", "base64", and "binary".

    For example, a FileDataSource could be created that forces all files to be base64 encoded:

      public class Base64FileDataSource extends FileDataSource
                                            implements EncodingAware {
            public Base64FileDataSource(File file) {
                super(file);
            }
    
            // implements EncodingAware.getEncoding()
            public String getEncoding() {
                return "base64";
            }
      }
