| Best Practices |
| |
| <ol class='spaced-list'> |
| <li> |
| Reuse instances of serializers and parsers whenever possible. |
| <br>They are designed to be thread safe and maintain internal caches of bean metadata to increase performance. |
| <li> |
| The {@link oaj.BeanTraverseContext#BEANTRAVERSE_detectRecursions BEANTRAVERSE_detectRecursions} |
| option on the {@link oaj.serializer.Serializer} class can cause a performance penalty of |
| around 20%. |
| <br>Therefore, it's recommended that this option be used only when necessary. |
| <li> |
| In general, JSON serialization and parsing is about 20% faster than XML. |
| JSON is also more compact than XML. |
| <br>MessagePack is fastest and most compact of all. |
| <li> |
| The RDF parsers are SLOW. |
| <br>RDF simply isn't efficient with node traversal, so creating tree structures out of RDF models |
| is highly inefficient. |
| <li> |
| The {@link oaj.parser.Parser} methods that take in {@link oaj.ClassMeta} |
| parameters are slightly faster than methods that |
| take in {@link java.lang.Class} or {@link java.lang.Object} parameters, since the latter methods involve |
| hash lookups to resolve to {@link oaj.ClassMeta} parameters. |
