Usage

From source file:com.cedarsoft.couchdb.io.CouchDocSerializer.java

public <T> void serialize(@Nonnull CouchDoc<T> doc, @Nonnull JacksonSerializer<? super T> wrappedSerializer,
        @Nonnull JsonGenerator generator) throws IOException {
    generator.writeStartObject();/*from   w  w  w.ja  va 2s.com*/
    RawCouchDocSerializer.serializeIdAndRev(generator, doc);

    //Type
    generator.writeStringField(AbstractJacksonSerializer.PROPERTY_TYPE, wrappedSerializer.getType());
    //Version
    generator.writeStringField(AbstractJacksonSerializer.PROPERTY_VERSION,
            wrappedSerializer.getFormatVersion().format());

    //The wrapped object
    wrappedSerializer.serialize(generator, doc.getObject(), wrappedSerializer.getFormatVersion());

    //The attachments - placed at the end
    serializeInlineAttachments(doc, generator);
