```
public class IlvDefaultDataColumnInfo
extends IlvAbstractDataColumnInfo
implements Cloneable, Serializable

- Constructor Detail
  - IlvDefaultDataColumnInfo
```
public IlvDefaultDataColumnInfo()
```
    Creates a column info with an empty name and value type String.
  - IlvDefaultDataColumnInfo
```
public IlvDefaultDataColumnInfo(String name,
                                Class type)
```
    Creates a column info with the given name and value type.
  - IlvDefaultDataColumnInfo
```
public IlvDefaultDataColumnInfo(String name,
                                Class type,
                                boolean enumerated)
```
    Creates a column info with the given name and value type, possibly enumerated.
- Method Detail
  - getName
```
public String getName()
```
    Returns the name of the column.
    The name is used in the chart display. It is used for accessing the column data only in some implementation of IlvModelWithColumns (such as IlvFlatListModel or IlvTreeListModel).
    
    Specified by:
    
    getName in interface IlvStaticColumnInfo
  - setName
```
public void setName(String name)
```
    Sets the name of the column.
    When using this function, you should make sure that two columns of the same IlvModelWithColumns do not have the same name.
    This method should not be called once this instance is already connected to an IlvModelWithColumns because no notification is sent when the name changes.
  - getType
```
public Class getType()
```
    Returns the value type of the column.
    
    Specified by:
    
    getType in interface IlvStaticColumnInfo
    
    Returns:
    
    A class to which all values of the column belong.
  - setType
```
public void setType(Class type)
```
    Sets the type of the values of this column.
    This method should not be called once this instance is already connected to an IlvModelWithColumns because no notification is sent when the type changes.
  - getEmptyValue
```
public Object getEmptyValue()
```
    Returns the replacement value when a record has no value for this column.
    
    Specified by:
    
    getEmptyValue in interface IlvDataColumnInfo
    
    Returns:
    
    A non-null object belonging to the getType() class.
  - setEmptyValue
```
public void setEmptyValue(Object emptyValue)
```
    Sets the replacement value when a record has no value for this column.
    
    Parameters:
    
    emptyValue - The new replacement for an empty value, should belong to the getType() class.
  - isEnumerated
```
public boolean isEnumerated()
```
    Returns true if this column stores enumerated values, meaning that there are only a few possible values.
    
    Specified by:
    
    isEnumerated in interface IlvDataColumnInfo
  - setEnumerated
```
public void setEnumerated(boolean enumerated)
```
    Sets the column to enumerated or not.
  - getEnumValues
```
public List getEnumValues()
```
    Returns the list of possible values if this column is enumerated.
    
    Specified by:
    
    getEnumValues in interface IlvDataColumnInfo
    
    Returns:
    
    An unmodifiable list of non-null objects, each one belonging to the getType() class, or null if the possible values are not fixed but depend on the contents of the model, or null if isEnumerated() is false.
  - setEnumValues
```
public void setEnumValues(List enumValues)
```
    Sets the list of possible values if this column is enumerated.
    
    Parameters:
    
    enumValues - A list of non-null objects, each belonging to the getType() class.
  - getEnumValue
```
public Object getEnumValue(int i)
```
    Returns one of the possible values.
    Note: This method can only be called after setEnumValues(java.util.List) has been called with a non-null list as argument.
  - setEnumValue
```
public void setEnumValue(int i,
                         Object value)
```
    Sets one of the possible values.
    Note: This method can only be called after setEnumValues(java.util.List) has been called with a non-null list as argument.
  - getMinValue
```
public Object getMinValue()
```
    Returns the theoretical minimum value of this column.
    
    Specified by:
    
    getMinValue in interface IlvDataColumnInfo
    
    Returns:
    
    A non-null object belonging to the getType() class, or null when there is no theoretical minimum.
  - setMinValue
```
public void setMinValue(Object min)
```
    Sets the theoretical minimum value of this column.
    
    Parameters:
    
    min - A non-null object belonging to the getType() class, or null when there is no theoretical minimum.
  - getMaxValue
```
public Object getMaxValue()
```
    Returns the theoretical maximum value of this column.
    
    Specified by:
    
    getMaxValue in interface IlvDataColumnInfo
    
    Returns:
    
    A non-null object belonging to the getType() class, or null when there is no theoretical maximum.
  - setMaxValue
```
public void setMaxValue(Object max)
```
    Sets the theoretical maximum value of this column.
    
    Parameters:
    
    max - A non-null object belonging to the getType() class, or null when there is no theoretical maximum.
  - clone
```
public Object clone()
```
    Returns a copy of this object.
    
    Specified by:
    
    clone in interface IlvStaticColumnInfo
    
    Overrides:
    
    clone in class IlvAbstractDataColumnInfo
