Package Summary Overview Summary

### class:DefaultRowSorter.ModelWrapper [NONE]
- 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. Since: 1.6 See Also: `RowFilter`, `RowFilter.Entry`

### constructor:ModelWrapper() [NONE]
- #### ModelWrapper
      protected ModelWrapper()
Creates a new `ModelWrapper`.

### method:getModel() [NONE]
- #### getModel
      public abstract M getModel()
Returns the underlying model that this `Model` is wrapping. Returns: the underlying model

### method:getColumnCount() [NONE]
- #### getColumnCount
      public abstract int getColumnCount()
Returns the number of columns in the model. Returns: the number of columns in the model

### method:getRowCount() [NONE]
- #### getRowCount
      public abstract int getRowCount()
Returns the number of rows in the model. Returns: the number of rows in the model

### method:getValueAt(int, int) [NONE]
- #### 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

### method:getStringValueAt(int, int) [NONE]
- #### 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

### method:getIdentifier(int) [NONE]
- #### 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 See Also: `RowFilter.Entry.getIdentifier()`
