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";
        }
  }
