ArrayOfNumbersSerDe (datasketches-java 4.1.0 API)

java.lang.Object
- org.apache.datasketches.common.ArrayOfItemsSerDe<Number>
- - org.apache.datasketches.common.ArrayOfNumbersSerDe

```
public class ArrayOfNumbersSerDe
extends ArrayOfItemsSerDe<Number>
```
Methods of serializing and deserializing arrays of the object version of primitive types of Number. The array can be a mix of primitive object types.
This class serializes numbers with a leading byte (ASCII character) indicating the type. The class keeps the values byte aligned, even though only 3 bits are strictly necessary to encode one of the 6 different primitives with object types that extend Number.

Classes handled are: Long, Integer, Short, Byte, Double, and Float.

public byte[] serializeToByteArray(Number[] items)
```
    Description copied from class: ArrayOfItemsSerDe
    
    Serialize an array of items to byte array. The size of the array doesn't need to be serialized. This method is called by the sketch serialization process.
    
    Specified by:
    
    serializeToByteArray in class ArrayOfItemsSerDe<Number>
    
    Parameters:
    
    items - array of items to be serialized
    
    Returns:
    
    serialized representation of the given array of items
  - deserializeFromMemory

public Number[] deserializeFromMemory(org.apache.datasketches.memory.Memory mem,
                                      int length)
```
    Description copied from class: ArrayOfItemsSerDe
    
    Deserialize an array of items from a given Memory object. This method is called by the sketch deserialization process.
    
    Specified by:
    
    deserializeFromMemory in class ArrayOfItemsSerDe<Number>
    
    Parameters:
    
    mem - Memory containing a serialized array of items
    
    length - number of items in the serialized array
    
    Returns:
    
    deserialized array of items
