Class TecDefaultRowSorter.ModelWrapper<M,I>

java.lang.Object

tecgraf.javautils.gui.table.TecDefaultRowSorter.ModelWrapper<M,I>

Type Parameters:

M - the type of the underlying model

I - the identifier supplied to the filter

Enclosing class:

TecDefaultRowSorter<M,I>

protected abstract static class TecDefaultRowSorter.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 Objects and Strings. 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
