Method Detail

addObjectSerializer

void addObjectSerializer(java.lang.Class c,
                         ObjectSerializer serializer)

Assign a ObjectSerializer to perform a type specific serialization scheme

Parameters:

c - this object's type serves as a key in the serialization map. ClassMapBasedObjectSerializer uses org.bson.util.ClassMap and not only checks if 'c' is a key in the Map, but also walks the up superclass and interface graph of 'c' to find matches. This means that it is only necessary assign ObjectSerializers to base classes. @see org.bson.util.ClassMap

serializer - performs the serialization mapping specific to the @param key type

serialize

public void serialize(java.lang.Object obj,
                      java.lang.StringBuilder buf)

Description copied from interface: ObjectSerializer

Serializes obj into buf.

Parameters:

obj - the object to be serialized

buf - StringBuilder containing the JSON representation of the object
