Custom Serialisation

You can register Serialisation / DeSerialisation code to Json-smart using JSONValue.registerWriter(Class<?> cls, JsonWriterI<T> writer) and JSONValue.registerReader(Class<T> type, JsonReaderI<T> mapper)

custom serialisation

Overwrite Serialisation is very easy

sample Example for Boolean serialisation

registerWriter(new JsonWriterI<Boolean>() {
  void writeJSONString(Boolean value, Appendable out, JSONStyle compression) throws IOException {
    out.append(value.toString());
  }
}, Boolean.class);

Custom deserialisation

JsonReaderI<T> Interface is more complex, and is an Class you will need to extand. JsonWriterI contains methods for Array, and Objects.

For Object creation

At runtime JsonReaderI methods will be called in this order:

startObject(theParentKey name)
createObject() // can return an non final type named TMP_CLS
getValue(key1) // may be call to check for colision
getType(key1) // must return the key final Class
setValue(TMP_CLS Object, key1, value1);
getValue(key2) // may be call to check for colision
getType(key2) // must return the key final Class
setValue(TMP_CLS Object, key2, value2);
convert(TMP_CLS Object); // convert or cast TMP_CLS to the final class

For Array create

At runtime JsonReaderI methods will be called in this order:

startArray(theParentKey name)
createObject() // can return an non final type named TMP_CLS
addValue(TMP_CLS Object, value1);
addValue(TMP_CLS Object, value2);
convert(TMP_CLS Object); // convert or cast TMP_CLS to the final class

since all Element in a array should have the same type, getType is not used in array creation
