public Header() Creates a new empty Header.
public Header(InputStream is) Creates a new Header from the specified stream. param is the stream to read the header from. final MimeStreamParser parser = new MimeStreamParser(); parser.setContentHandler(new AbstractContentHandler() { public void endHeader() { parser.stop(); } public void field(String fieldData) { addField(Field.parse(fieldData)); } }); parser.parse(is);

Methods Summary
public void	addField(org.apache.james.mime4j.field.Field field) Adds a field to the end of the list of fields. param field the field to add. List values = (List) fieldMap.get(field.getName().toLowerCase()); if (values == null) { values = new LinkedList(); fieldMap.put(field.getName().toLowerCase(), values); } values.add(field); fields.add(field);
public org.apache.james.mime4j.field.Field	getField(java.lang.String name) Gets a Field given a field name. If there are multiple such fields defined in this header the first one will be returned. param name the field name (e.g. From, Subject). return the field or null if none found. List l = (List) fieldMap.get(name.toLowerCase()); if (l != null && !l.isEmpty()) { return (Field) l.get(0); } return null;
public java.util.List	getFields() Gets the fields of this header. The returned list will not be modifiable. return the list of Field objects. return Collections.unmodifiableList(fields);
public java.util.List	getFields(java.lang.String name) Gets all Fields having the specified field name. param name the field name (e.g. From, Subject). return the list of fields. List l = (List) fieldMap.get(name.toLowerCase()); return Collections.unmodifiableList(l);
public java.lang.String	toString() Return Header Object as String representation. Each headerline is seperated by "\r\n" return headers StringBuffer str = new StringBuffer(); for (Iterator it = fields.iterator(); it.hasNext();) { str.append(it.next().toString()); str.append("\r\n"); } return str.toString();
public void	writeTo(java.io.OutputStream out) Write the Header to the given OutputStream param out the OutputStream to write to throws IOException String charString = ((ContentTypeField) getField(Field.CONTENT_TYPE)).getCharset(); BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(out, CharsetUtil.getCharset(charString)),8192); writer.write(toString()+ "\r\n"); writer.flush();
