Class DefaultRowSorter.ModelWrapper<M,I>
- java.lang.Object
-
- javax.swing.DefaultRowSorter.ModelWrapper<M,I>
- Type Parameters:
-
M
- the type of the underlying model -
I
- the identifier supplied to the filter
- Enclosing class:
- DefaultRowSorter<M,I>
protected abstract static class DefaultRowSorter.ModelWrapper<M,I> extends Object
DefaultRowSorter.ModelWrapper
is responsible for providing the data that gets sorted by DefaultRowSorter
. You normally do not interact directly with ModelWrapper
. Subclasses of DefaultRowSorter
provide an implementation of ModelWrapper
wrapping another model. For example, TableRowSorter
provides a ModelWrapper
that wraps a TableModel
.
ModelWrapper
makes a distinction between values as Object
s and String
s. This allows implementations to provide a custom string converter to be used instead of invoking toString
on the object.

Method Detail
getModel
public abstract M getModel()
Returns the underlying model that this Model
is wrapping.
- Returns:
- the underlying model
getColumnCount
public abstract int getColumnCount()
Returns the number of columns in the model.
- Returns:
- the number of columns in the model
getRowCount
public abstract int getRowCount()
Returns the number of rows in the model.
- Returns:
- the number of rows in the model
getValueAt
public abstract Object getValueAt(int row, int column)
Returns the value at the specified index.
- Parameters:
-
row
- the row index -
column
- the column index - Returns:
- the value at the specified index
- Throws:
-
IndexOutOfBoundsException
- if the indices are outside the range of the model
getStringValueAt
public String getStringValueAt(int row, int column)
Returns the value as a String
at the specified index. This implementation uses toString
on the result from getValueAt
(making sure to return an empty string for null values). Subclasses that override this method should never return null.
- Parameters:
-
row
- the row index -
column
- the column index - Returns:
- the value at the specified index as a
String
- Throws:
-
IndexOutOfBoundsException
- if the indices are outside the range of the model
getIdentifier
public abstract I getIdentifier(int row)
Returns the identifier for the specified row. The return value of this is used as the identifier for the RowFilter.Entry
that is passed to the RowFilter
.
- Parameters:
-
row
- the row to return the identifier for, in terms of the underlying model - Returns:
- the identifier
