public void setConverters(Set<?> converters)
Converter

instances to be used that will take presidence over
using object traversal to convert and object to/from DBObject
converters
- public void write(Object obj, DBObject dbo)
MongoWriter
write
in interface MongoWriter<Object>
obj
- The object to convert to a DBObjectdbo
- The DBObject to use for writing.protected void writeMap(DBObject dbo, String mapKey, Map<String,Object> map)
Map
to the given DBObject
.
dbo
- mapKey
- map
- protected void writeArray(DBObject dbo, String keyToUse, Object[] array)
DBObject
.
dbo
- keyToUse
- array
- public <S> S read(Class<S> clazz, DBObject source)
MongoReader
DBObject
into it. So in case there's no real valid data inside
DBObject
for the given type, just return an empty instance of the given type.
read
in interface MongoReader<Object>
clazz
- the type of the return valuesource
- theDBObject
protected Map<String,Object> createMap()
Map
instance. Will return a HashMap
by default. Subclasses might want to override this
method to use a custom Map
implementation.
protected Map<?,?> readMap(MongoPropertyDescriptors.MongoPropertyDescriptor pd, DBObject dbo, Class<?> targetType)
DBObject
into a Map
instance.

public <T> T convertObjectId(ObjectId id, Class<T> targetType)
MongoConverter
ObjectId
to the given target type.
convertObjectId
in interface MongoConverter
T
- the actual type to createid
- the source ObjectId
