BsonArrayCodec

public BsonArrayCodec()

Creates a new instance with a default codec registry that uses the BsonValueCodecProvider.

Since:

3.4

BsonArrayCodec

public BsonArrayCodec(CodecRegistry codecRegistry)

Construct an instance with the given registry

Parameters:

codecRegistry - the codec registry

Method Detail

decode

public BsonArray decode(BsonReader reader,
                        DecoderContext decoderContext)

Description copied from interface: Decoder

Decodes a BSON value from the given reader into an instance of the type parameter T.

Specified by:

decode in interface Decoder<BsonArray>

Parameters:

reader - the BSON reader

decoderContext - the decoder context

Returns:

an instance of the type parameter T.

encode

public void encode(BsonWriter writer,
                   BsonArray array,
                   EncoderContext encoderContext)

Description copied from interface: Encoder

Encode an instance of the type parameter T into a BSON value.

Specified by:

encode in interface Encoder<BsonArray>

Parameters:

writer - the BSON writer to encode into

array - the value to encode

encoderContext - the encoder context

getEncoderClass

public java.lang.Class<BsonArray> getEncoderClass()

Description copied from interface: Encoder

Returns the Class instance that this encodes. This is necessary because Java does not reify generic types.

Specified by:

getEncoderClass in interface Encoder<BsonArray>

Returns:

the Class instance that this encodes.

readValue

protected BsonValue readValue(BsonReader reader,
                              DecoderContext decoderContext)

This method may be overridden to change the behavior of reading the current value from the given BsonReader. It is required that the value be fully consumed before returning.

Parameters:

reader - the read to read the value from

decoderContext - the decoder context

Returns:

the non-null value read from the reader
