Method Details

serializedSize

int serializedSize(@Nullable V value)

serialize

@NonNull ByteBuffer serialize(@Nullable V value,
 @NonNull ByteBuffer target)

Serialize value into target, returns target.

deserialize

@Nullable V deserialize(@NonNull ByteBuffer buffer)

Deserialize a value from buffer. Implementations must not assume that the given ByteBuffer only contains data for the value to deserialize, other data likely follows.

isNullSerialized

boolean isNullSerialized(@NonNull ByteBuffer buffer)

Determines whether the serialized value at the current buffer position represents null.

Implementations must not modify the caller-visible state of buffer.

skip

void skip(@NonNull ByteBuffer buffer)

Skips an element, only updating the buffer's Buffer.position().
