LazyBSONCallback

public LazyBSONCallback()

方法详细资料

reset

public void reset()

从接口复制的说明: BSONCallback

Resets the callback, clearing all state.

指定者:

reset 在接口中 BSONCallback

覆盖:

reset 在类中 EmptyBSONCallback

get

public java.lang.Object get()

从接口复制的说明: BSONCallback

Returns the finished top-level Document.

指定者:

get 在接口中 BSONCallback

覆盖:

get 在类中 EmptyBSONCallback

返回:

the top level document read from the database.

gotBinary

public void gotBinary(java.lang.String name,
                      byte type,
                      byte[] data)

从接口复制的说明: BSONCallback

Called when reading a field with a BsonType.BINARY value. Note that binary values have a subtype, which may determine how the value is processed.

指定者:

gotBinary 在接口中 BSONCallback

覆盖:

gotBinary 在类中 EmptyBSONCallback

参数:

name - the name of the field

type - one of the binary subtypes: BsonBinarySubType

data - the field's value

createObject

public java.lang.Object createObject(byte[] bytes,
                                     int offset)

Create a LazyBSONObject instance from the given bytes starting from the given offset.

参数:

bytes - the raw BSON bytes

offset - the offset into the bytes

返回:

the LazyBSONObject

createArray

public java.util.List createArray(byte[] bytes,
                                  int offset)

Create a LazyBSONList from the given bytes starting from the given offset.

参数:

bytes - the raw BSON bytes

offset - the offset into the bytes

返回:

the LazyBSONList

createDBRef

public java.lang.Object createDBRef(java.lang.String ns,
                                    ObjectId id)

This is a factory method pattern to create appropriate objects for BSON type DBPointer(0x0c).

参数:

ns - the namespace of the reference

id - the identifier of the reference

返回:

object to be used as reference representation
