public class BufferedBerStream

extends BufferedInputStream

BufferedBerStream is a class to sequentially read BER records from an InputStream. Here is an example that opens a file, reads all the records and prints each record.

BufferedBerStream berStream = null;
BerString berRec;
//
try { berStream = new BufferedBerStream(new FileInputStream("berfile")); }
catch (FileNotFoundException n) {
System.out.println(n.toString());
return;
}
//
while (true) {
try { berRec = berStream.readBerString(); 
System.out.println(berRec.toString());
}
catch (FileNotFoundException n) {
System.out.println(n.toString());
return;
} catch (EOFException n) {
System.out.println(n.toString());
return;
} catch (IOException n) {
System.out.println(n.toString());
return;
}
}
