Interface NodeModel

public interface NodeModel

A model for any columnar information of a tree node. It encapsulates the methods which a TreeTableModel must implement in addition to those of a TreeModel. It is used by a TreeTableModelAdapter to expose a TreeModel as a TreeTableModel.

Modifier and Type	Method and Description
java.lang.Class<?>	getColumnClass(int column) Returns the most specific superclass for all the cell values in the column.
int	getColumnCount() Returns the number of columns in the model.
java.lang.String	getColumnName(int column) Returns the name of the column at columnIndex.
int	getHierarchicalColumn() Returns the column that is the "tree" column.
java.lang.Object	getValueAt(java.lang.Object node, int column) Returns the value for the node at columnIndex.
boolean	isCellEditable(java.lang.Object node, int column) Returns true if the cell for the node at columnIndex is editable.
void	setValueAt(java.lang.Object value, java.lang.Object node, int column) Sets the value for the node at columnIndex to value.

Method Detail

getColumnClass

java.lang.Class<?> getColumnClass(int column)

Returns the most specific superclass for all the cell values in the column. This is used by the JXTreeTable to set up a default renderer and editor for the column.

Parameters:

columnIndex - the index of the column

Returns:

the common ancestor class of the object values in the model.

See Also:

TableModel.getColumnClass(int)

getColumnCount

int getColumnCount()

Returns the number of columns in the model. A JXTreeTable uses this method to determine how many columns it should create and display by default.

Returns:

the number of columns in the model

See Also:

TableModel.getColumnCount()

getColumnName

java.lang.String getColumnName(int column)

Returns the name of the column at columnIndex. This is used to initialize the table's column header name. Note: this name does not need to be unique; two columns in a table can have the same name.

Parameters:

column - the index of the column

Returns:

the name of the column

See Also:

TableModel.getColumnName(int)

getHierarchicalColumn

int getHierarchicalColumn()

Returns the column that is the "tree" column. While it is not required, most implementations will default the first column to be the hierarchical one.

Returns:

the index of the hierarchical column or -1 if no column is the hierarchical column.

getValueAt

java.lang.Object getValueAt(java.lang.Object node,
                            int column)

Returns the value for the node at columnIndex. The node must be managed by this model. Unamanaged nodes should throw an IllegalArgumentException.

Parameters:

node - the node whose value is to be queried

column - the column whose value is to be queried

Returns:

the value Object at the specified cell

Throws:

java.lang.IllegalArgumentException - if node is not managed by this model.

See Also:

setValueAt(java.lang.Object, java.lang.Object, int), TableModel.getValueAt(int, int)

isCellEditable

boolean isCellEditable(java.lang.Object node,
                       int column)

Returns true if the cell for the node at columnIndex is editable. Otherwise, setValueAt on the cell will not change the value of that cell. The node must be managed by this model. Unamanaged nodes should throw an IllegalArgumentException.

Parameters:

node - the node whose value to be queried

column - the column whose value to be queried

Returns:

true if the cell is editable

Throws:

java.lang.IllegalArgumentException - if node is not managed by this model.

See Also:

setValueAt(java.lang.Object, java.lang.Object, int), TableModel.isCellEditable(int, int)

setValueAt

void setValueAt(java.lang.Object value,
                java.lang.Object node,
                int column)

Sets the value for the node at columnIndex to value. The node must be managed by this model. Unamanaged nodes should throw an IllegalArgumentException.

Parameters:

value - the new value

node - the node whose value is to be changed

column - the column whose value is to be changed

Throws:

java.lang.IllegalArgumentException - if node is not managed by this model.
