Class JSONWriterRecord

java.lang.Object
  org.eclipse.persistence.internal.sessions.AbstractRecord
      org.eclipse.persistence.oxm.record.XMLRecord
          org.eclipse.persistence.oxm.record.MarshalRecord
              org.eclipse.persistence.oxm.record.JSONWriterRecord

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map, Record

Direct Known Subclasses:

JSONFormattedWriterRecord

public class JSONWriterRecord
extends MarshalRecord

Use this type of MarshalRecord when the marshal target is a Writer and the JSON should not be formatted with carriage returns or indenting.

XMLContext xmlContext = new XMLContext("session-name");
XMLMarshaller xmlMarshaller = xmlContext.createMarshaller();
JSONRecord jsonWriterRecord = new JSONWriterRecord();
jsonWriterRecord.setWriter(myWriter);
xmlMarshaller.marshal(myObject, jsonWriterRecord);


If the marshal(Writer) and setMediaType(MediaType.APPLICATION_JSON) and setFormattedOutput(false) method is called on XMLMarshaller, then the Writer is automatically wrapped in a JSONWriterRecord.

XMLContext xmlContext = new XMLContext("session-name");
XMLMarshaller xmlMarshaller = xmlContext.createMarshaller();
xmlMarshaller.setMediaType(MediaType.APPLICATION_JSON); xmlMarshaller xmlMarshaller.setFormattedOutput(false);
xmlMarshaller.marshal(myObject, myWriter);

Nested Class Summary

protected class	JSONWriterRecord.JSONWriterRecordContentHandler This class will typically be used in conjunction with an XMLFragmentReader.
protected static class	JSONWriterRecord.Level Instances of this class are used to maintain state about the current level of the JSON message being marshalled.
