      • parseColumn

        public java.util.Collection<EntryType> parseColumn​(java.nio.ByteBuffer buffer,
                                                   int length)
        Description copied from interface: ColumnType
        Parses a value of this type from buffer. Value will be parsed from current position of the buffer. After completion of the function, position will be moved by "length" bytes.
        Specified by:
        parseColumn in interface ColumnType<EntryType>
        Parameters:
        buffer - Buffer to parse column from
        length - Serialized value size in buffer is as big as length
        Returns:
        value as Java type

      • serialize

        public java.nio.ByteBuffer serialize​(java.util.Collection<EntryType> value)
        Description copied from interface: ColumnType
        Serialize into ByteBuffer and keeps the position at beginning of ByteBuffer
        Specified by:
        serialize in interface ColumnType<EntryType>
        Parameters:
        value - the value to serialize
        Returns:
