```
    Constructs an instance by the given blob
    
    Parameters:
    
    blob - the given blob
    
    Throws:
    
    java.sql.SQLException - if an error is encountered during serialization, or if blob is null
  - HarmonySerialBlob
```
public HarmonySerialBlob(byte[] buf)
```
    Constructs an instance by the given buf
    
    Parameters:
    
    buf - the given buffer
    
    Throws:
