Modifier and Type	Method	Description
`LocalDate`	`decode(BsonReader reader, DecoderContext decoderContext)`	Decodes a BSON value from the given reader into an instance of the type parameter `T`.

  - decode
```
public LocalDate 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.
    
    Parameters:
    
    reader - the BSON reader
    
    decoderContext - the decoder context
    
    Returns:
    
    an instance of the type parameter T.
  - encode
```
public void encode(BsonWriter writer,
                   LocalDate value,
                   EncoderContext encoderContext)
```
    Encode an instance of the type parameter T into a BSON value.
    Converts the LocalDate to ZoneOffset.UTC via LocalDate.atStartOfDay(ZoneId).
    
    Parameters:
    
    writer - the BSON writer to encode into
    
    value - the value to encode
    
    encoderContext - the encoder context
    
    Throws:
    
    CodecConfigurationException - if the LocalDate cannot be converted to a valid Bson DateTime.
  - getEncoderClass
```
public Class<LocalDate> getEncoderClass()
```
    Description copied from interface: Encoder
    
    Returns the Class instance that this encodes. This is necessary because Java does not reify generic types.
    
    Returns:
    
    the Class instance that this encodes.
