Constructor Detail

TableAdapter

public TableAdapter(JXTable component)

Constructs a TableDataAdapter for the specified target component.

Parameters:

component - the target component

Method Detail

getTable

public JXTable getTable()

Typesafe accessor for the target component.

Returns:

the target component as a JTable

getColumnName

public String getColumnName(int columnIndex)

Returns the column's display name (= headerValue) of the column at columnIndex in model coordinates. Used f.i. in SearchPanel to fill the field with the column name.

Note: it's up to the implementation to decide for which columns it returns a name - most will do so for the subset with isTestable = true. This implementation delegates to getColumnIdentifierAt and returns it's toString or null.

Overrides:

getColumnName in class ComponentAdapter

Parameters:

columnIndex - in model coordinates

Returns:

column name or null if not found

getColumnByModelIndex

protected TableColumn getColumnByModelIndex(int modelColumn)

Returns the first contained TableColumn with the given model index, or null if none is found.

Parameters:

modelColumn - the column index in model coordinates, must be valid

Returns:

the first contained TableColumn with the given model index, or null if none is found

Throws:

IllegalArgumentExcetpion - if model index invalid

getColumnIdentifierAt

public Object getColumnIdentifierAt(int columnIndex)

Returns logical identifier of the column at columnIndex in model coordinates. Note: it's up to the implementation to decide for which columns it returns an identifier - most will do so for the subset with isTestable = true.

This implementation returns DEFAULT_COLUMN_IDENTIFIER. PENDING JW: This method replaces the old getColumnIdentifier(int) which returned a String which is overly restrictive. The only way to gently replace this method was to add this with a different name - which makes this name suboptimal. Probably should rename again once the old has died out ;-)

Overrides:

getColumnIdentifierAt in class ComponentAdapter

Parameters:

columnIndex - in model coordinates, must be valid.

Returns:

the identifier of the column at columnIndex or null if it has none.

See Also:

ComponentAdapter.getColumnIndex(Object)

getColumnIndex

public int getColumnIndex(Object identifier)

Returns the column index in model coordinates for the logical identifier.

This implementation returns 0 if the identifier is the same as the one known identifier returned from getColumnIdentifierAt(0), or -1 otherwise. So subclasses with one column and a customizable identifier need not override. Subclasses which support multiple columns must override this as well to keep the contract as in (assuming that the lookup succeeded):

  Object id = getColumnIdentifierAt(index);
  assertEquals(index, getColumnIndex(index);
  // and the reverse 
  int column = getColumnIndex(identifier);
  assertEquals(identifier, getColumnIdentifierAt(column));
 

Overrides:

getColumnIndex in class ComponentAdapter

Parameters:

identifier - the column's identifier, must not be null

Returns:

the index of the column identified by identifier in model coordinates or -1 if no column with the given identifier is found.

See Also:

ComponentAdapter.getColumnIdentifierAt(int)

getColumnClass

public Class<?> getColumnClass(int column)

Description copied from class: ComponentAdapter

Returns the common class of all data column identified by the given column index in model coordinates.

This implementation returns Object.class. Subclasses should implement as appropriate.

Overrides:

getColumnClass in class ComponentAdapter

Returns:

the common class of all data given column in model coordinates.

See Also:

ComponentAdapter.getColumnClass()

getColumnCount

public int getColumnCount()

Returns the number of columns in the target's data model.

Overrides:

getColumnCount in class ComponentAdapter

Returns:

the number of columns in the target's data model.

getRowCount

public int getRowCount()

Returns the number of rows in the target's data model.

Overrides:

getRowCount in class ComponentAdapter

Returns:

the number of rows in the target's data model.

getValueAt

public Object getValueAt(int row,
                         int column)

Returns the value of the target component's cell identified by the specified row and column in model coordinates.

Specified by:

getValueAt in class ComponentAdapter

Parameters:

row - in model coordinates

column - in model coordinates

Returns:

the value of the target component's cell identified by the specified row and column

isCellEditable

public boolean isCellEditable(int row,
                              int column)

Determines whether this cell is editable.

Specified by:

isCellEditable in class ComponentAdapter

Parameters:

row - the row to query in model coordinates

column - the column to query in model coordinates

Returns:

true if the cell is editable, false otherwise

isTestable

public boolean isTestable(int column)

Returns true if the column should be included in testing.

Here: returns true if visible (that is modelToView gives a valid view column coordinate).

Overrides:

isTestable in class ComponentAdapter

Parameters:

column - the column index in model coordinates

Returns:

true if the column should be included in testing

getStringAt

public String getStringAt(int row,
                          int column)

Returns the String representation of the value of the cell identified by the row specified row and column in model coordinates.

This implementation messages the StringValue.TO_STRING with the valueAt, subclasses should re-implement and use the api appropriate for the target component type.

This is implemented to query the table's StringValueRegistry for an appropriate StringValue and use that for getting the string representation.

Overrides:

getStringAt in class ComponentAdapter

Parameters:

row - in model coordinates

column - in model coordinates

Returns:

the value of the target component's cell identified by the specified row and column

getCellBounds

public Rectangle getCellBounds()

Returns the bounds of the cell identified by this adapter.

Overrides:

getCellBounds in class ComponentAdapter

Returns:

the bounds of the cell identified by this adapter

isEditable

public boolean isEditable()

Returns true if the cell identified by this adapter is editable, false otherwise.

Specified by:

isEditable in class ComponentAdapter

Returns:

true if the cell is editable, false otherwise

isSelected

public boolean isSelected()

Returns true if the cell identified by this adapter is currently selected. Otherwise, it returns false.

Specified by:

isSelected in class ComponentAdapter

Returns:

true if the cell identified by this adapter is currently selected; Otherwise, return false

hasFocus

public boolean hasFocus()

Returns true if the cell identified by this adapter currently has focus. Otherwise, it returns false.

Specified by:

hasFocus in class ComponentAdapter

Returns:

true if the cell identified by this adapter currently has focus; Otherwise, return false

convertColumnIndexToView

public int convertColumnIndexToView(int columnIndex)

For target components that support multiple columns in their model, along with column reordering in the view, this method transforms the specified columnIndex from model coordinates to view coordinates. For all other types of target components, this method returns the columnIndex unchanged.

Overrides:

convertColumnIndexToView in class ComponentAdapter

Parameters:

columnIndex - index of a column in model coordinates

Returns:

index of the specified column in view coordinates

convertColumnIndexToModel

Overrides:

convertColumnIndexToModel in class ComponentAdapter

Parameters:

columnIndex - index of a column in view coordinates

Returns:

index of the specified column in model coordinates

convertRowIndexToView

public int convertRowIndexToView(int rowModelIndex)

convertRowIndexToModel

public int convertRowIndexToModel(int rowViewIndex)

Converts a row index in view coordinates to an index in model coordinates.
