M- the type of the underlying modelI- the identifier supplied to the filter
- Enclosing class:
- DefaultRowSorter<M,I>
protected abstract static class DefaultRowSorter.ModelWrapper<M,I> extends Object
DefaultRowSorter.ModelWrapperis responsible for providing the data that gets sorted byDefaultRowSorter. You normally do not interact directly withModelWrapper. Subclasses ofDefaultRowSorterprovide an implementation ofModelWrapperwrapping another model. For example,TableRowSorterprovides aModelWrapperthat wraps aTableModel.ModelWrappermakes a distinction between values asObjects andStrings. This allows implementations to provide a custom string converter to be used instead of invokingtoStringon the object.- Since:

Method Detail
-
getModel
public abstract M getModel()
Returns the underlying model that thisModelis 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 indexcolumn- 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 aStringat the specified index. This implementation usestoStringon the result fromgetValueAt(making sure to return an empty string for null values). Subclasses that override this method should never return null.- Parameters:
row- the row indexcolumn- 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 theRowFilter.Entrythat is passed to theRowFilter.- Parameters:
row- the row to return the identifier for, in terms of the underlying model- Returns:
- the identifier

RowFilter.Entry.getIdentifier()
