```
public class ArrayOfUtf16StringsSerDe
extends ArrayOfItemsSerDe<String>
```
Methods of serializing and deserializing arrays of String. This class serializes strings using internal Java representation as char[], where each char is a 16-bit code. The result is larger than one from ArrayOfStringsSerDe. In an extreme case when all strings are in ASCII, the size is doubled. However it takes less time to serialize and deserialize by a factor of 1.5 to 2.

    serializeToByteArray in class ArrayOfItemsSerDe<String>
    
    Parameters:
    
    items - array of items to be serialized
    
    Returns:
    
    serialized representation of the given array of items
  - deserializeFromMemory
