Class MarcStreamWriter

java.lang.Object

org.marc4j.MarcStreamWriter

All Implemented Interfaces:

MarcWriter

Direct Known Subclasses:

MarcSplitStreamWriter, MarcSplitStreamWriter

public class MarcStreamWriter
extends Object
implements MarcWriter

Class for writing MARC record objects in ISO 2709 format.

The following example reads a file with MARCXML records and outputs the record set in ISO 2709 format:

 InputStream input = new FileInputStream("marcxml.xml");
 MarcXmlReader reader = new MarcXmlReader(input);
 MarcWriter writer = new MarcStreamWriter(System.out);
 while (reader.hasNext()) {
     Record record = reader.next();
     writer.write(record);
 }
 writer.close();
 

To convert characters like for example from UCS/Unicode to MARC-8 register a CharConverter implementation:

 InputStream input = new FileInputStream("marcxml.xml");
 MarcXmlReader reader = new MarcXmlReader(input);
 MarcWriter writer = new MarcStreamWriter(System.out);
 writer.setConverter(new UnicodeToAnsel());
 while (reader.hasNext()) {
     Record record = reader.next();
     writer.write(record);
 }
 writer.close();
