BsonDocumentWrapper (mongo-java-driver 3.3.0-query-log-max-size API)

java.lang.Object
- org.bson.BsonValue
- - org.bson.BsonDocument
  - - org.bson.BsonDocumentWrapper<T>

类型参数:

T - the type of the document that is wrapped

所有已实现的接口:

java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.String,BsonValue>, Bson, CountedBytes
```
public final class BsonDocumentWrapper<T>
extends BsonDocument
```
A BsonDocument that begins its life as a document of any type and an Encoder for that document, which lets an instance of any class with an Encoder be treated as a BsonDocument. If any methods are called which required access to the individual elements of the document, then, on demand, the document will be unwrapped into a BsonDocument using a BsonDocumentWriter and the Encoder. But if all that is done with this document is to encode it, then the Encoder will be used to do that.

从以下版本开始:

3.0
