Method Detail

reset

public void reset()

Description copied from interface: BSONCallback

Resets the callback, clearing all state.

Specified by:

reset in interface BSONCallback

Overrides:

reset in class EmptyBSONCallback

get

public Object get()

Description copied from interface: BSONCallback

Returns the finished top-level Document.

Specified by:

get in interface BSONCallback

Overrides:

get in class EmptyBSONCallback

Returns:

the top level document read from the database.

gotBinary

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

Description copied from interface: 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.

Specified by:

gotBinary in interface BSONCallback

Overrides:

gotBinary in class EmptyBSONCallback

Parameters:

name - the name of the field

type - one of the binary subtypes: BsonBinarySubType

data - the field's value

createObject

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

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

Parameters:

bytes - the raw BSON bytes

offset - the offset into the bytes

Returns:

the LazyBSONObject

createArray

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

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

Parameters:

bytes - the raw BSON bytes

offset - the offset into the bytes

Returns:

the LazyBSONList

createDBRef

public Object createDBRef(String ns,
                          ObjectId id)

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

Parameters:

ns - the namespace of the reference

id - the identifier of the reference

Returns:

object to be used as reference representation
