- Method Detail
  - editor
```
static ColumnEditor editor()
```
    Obtain an column definition editor that can be used to define a column.
    
    Returns:
    
    the editor; never null
  - name
```
String name()
```
    Get the name of the column.
    
    Returns:
    
    the column name; never null
  - position
```
int position()
```
    Get the position of the column in the table.
    
    Returns:
    
    the 1-based position
  - jdbcType
```
int jdbcType()
```
    Get the JDBC type for this column
    
    Returns:
    
    the type constant
  - typeName
```
String typeName()
```
    Get the database-specific name of the column's data type.
    
    Returns:
    
    the name of the type
  - length
```
int length()
```
    Get the maximum length of this column's values. For numeric columns, this represents the precision.
    
    Returns:
    
    the length of the column
  - scale
```
int scale()
```
    Get the scale of the column.
    
    Returns:
    
    the scale, or -1 if the scale does not apply to this type
  - isOptional
```
boolean isOptional()
```
    Determine whether this column is optional.
    
    Returns:
    
    true if it is optional, or false otherwise
    
    See Also:
    
    isRequired()
  - isRequired
```
default boolean isRequired()
```
    Determine whether this column is required. This is equivalent to calling !isOptional().
    
    Returns:
    
    true if it is required (not optional), or false otherwise
    
    See Also:
    
    isOptional()
  - isAutoIncremented
```
boolean isAutoIncremented()
```
    Determine whether this column's values are automatically incremented by the database.
    
    Returns:
    
    true if the values are auto-incremented, or false otherwise
  - isGenerated
```
boolean isGenerated()
```
    Determine whether this column's values are generated by the database.
    
    Returns:
    
    true if the values are generated, or false otherwise
  - compareTo
```
default int compareTo(Column that)
```
    Specified by:
    
    compareTo in interface Comparable<Column>
  - edit
```
default ColumnEditor edit()
```
    Obtain an editor that contains the same information as this column definition.
    
    Returns:
    
    the editor; never null
