方法详细资料

encode

public void encode(BsonWriter writer,
                   java.lang.Double value,
                   EncoderContext encoderContext)

从接口复制的说明: Encoder

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

指定者:

encode 在接口中 Encoder<java.lang.Double>

参数:

writer - the BSON writer to encode into

value - the value to encode

encoderContext - the encoder context

decode

public java.lang.Double decode(BsonReader reader,
                               DecoderContext decoderContext)

从接口复制的说明: Decoder

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

指定者:

decode 在接口中 Decoder<java.lang.Double>

参数:

reader - the BSON reader

decoderContext - the decoder context

返回:

an instance of the type parameter T.

getEncoderClass

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

从接口复制的说明: Encoder

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

指定者:

getEncoderClass 在接口中 Encoder<java.lang.Double>

返回:

the Class instance that this encodes.
