The document explains the processes of deserialization and serialization, detailing how to convert strings to objects and vice versa. It outlines where to use these processes, such as in REST APIs and web application forms, while emphasizing the need for explicit mappings per class. Additionally, it provides methods for using both the deserializer and serializer effectively.

1. Deserialize/Serialize
in a simple but powerful way

2. What is deserialization about?
Its all about coverting a string to an object
• decode: (json, url-encoded, yaml, xml) => array
• denormalize: array => object

3. Where to use deserialization?
• Rest APIs
• Webapplication forms

4. But why not using JMS/Symfony?
• denormalize recursive structure within existing objects

5. Howto use the deserializer?
• define one mapping per class (explicit > implicit)
• 3 methods (getClass, getDenormalizationFactory,
getDenormalizationFieldMappings)

6. getDenormalizationFactory

7. getDenormalizationFieldMappings

8. What is serialization about?
Its all about coverting a object to a string
• normalize: object => array
• encode: array => (json, url-encoded, yaml, xml)

9. Where to use serialization?
• Rest(ful) APIs

10. But why not using JMS/Symfony?
• there is no link support
• have a consistent tool on de/serialize

11. Howto use the serializer?
• define one mapping per class (explicit > implicit)
• 4 methods (getClass, getNormalizationType,
getNormalizationFieldMappings,
getNormalizationEmbeddedFieldMappings,
getNormalizationLinkMappings)

12. getNormalizationType

13. getNormalizationFieldMappings
getNormalizationFieldMappingsgetNormalizationFieldMappings

14. getNormalizationEmbeddedFieldMappings

15. getNormalizationLinkMappings
