Modifier and Type	Method	Description
`int`	`compareTo(Object o)`
`String`	`getName()`	The name for this column.
`int`	`getType()`	it is strongly suggested that you use `Types` since these are stable and pretty easily map to most interesting data types.
`boolean`	`isNullable()`	If this column may be nulled.

```
public DataDescriptorEntry(String name,
                           int type)
```
  - DataDescriptorEntry
```
public DataDescriptorEntry(String name,
                           int type,
                           boolean nullable)
```
- Method Detail
  - isNullable
```
public boolean isNullable()
```
    If this column may be nulled.
    Update for version 5.0+: Changed default from false to true since non primary key entries consistently blow up. If this is to be required, set it explicitly to true now.
    
    Returns:
  - setNullable
```
public void setNullable(boolean nullable)
```
  - getName
```
public String getName()
```
    The name for this column. This will be used in the resulting table.
    
    Returns:
  - setName
```
public void setName(String name)
```
  - getType
```
public int getType()
```
    it is strongly suggested that you use Types since these are stable and pretty easily map to most interesting data types. These (within rather narrow limits) are converted by the database abstraction layer to the correct underlying data type. E.g. a BLOB would become a LONG VARCHAR FOR BIT DATA in a DB2 implementation.
    
    Returns:
  - setType
```
public void setType(int type)
```
  - compareTo
```
public int compareTo(Object o)
```
