```
public static byte[] makeColumn(byte[] family,

```
    Makes a column in family:qualifier form from separate byte arrays.
    Not recommended for usage as this is old-style API.
    
    Parameters:
    
    family -
    
    qualifier -
    
    Returns:
    
    family:qualifier
  - parseColumn
```
public static byte[][] parseColumn(byte[] c)
```
    Splits a column in family:qualifier form into separate byte arrays. An empty qualifier (ie, fam:) is parsed as { fam, EMPTY_BYTE_ARRAY } while no delimiter (ie, fam) is parsed as an array of one element, { fam }.
    Don't forget, HBase DOES support empty qualifiers. (see HBASE-9549)
    
    Not recommend to be used as this is old-style API.
    
    Parameters:
    
    c - The column.
    
    Returns:
    
    The parsed column.
