Field Summary

protected ArrayList	colspanForCells
protected boolean	columnAutoCreated
protected Vector	columns

Constructor Summary

JCOTableViewModel(JCO.Table table)
constructs a table model from a jco table

JCOTableViewModel(JCO.Table table, boolean columnAutoCreated)
constructs a table model from a jco table if columnAutoCreated is true, the columns will be automatically generated otherwise the columns have to be added to the table via method addColumn() later

Method Summary

TableColumn	addColumn(String columnName) adds a column with the name columnName to the table
void	addKeyColumn(int columnIndex) adds the column at columnIndex as one of the key columns
TableColumn	getColumnAt(int columnIndex) returns the column at columnIndex
int	getColumnCount() returns the number of visible columns in the table
String	getColumnName(int columnIndex) returns the title of the column with columnIndex
Vector	getColumns() returns the columns of the table
IndexedLinkedList	getKeyColumn() returns the key column
int	getRowCount() returns the number of rows in the model
AbstractDataType	getValueAt(int rowIndex, int columnIndex) Returns the value for the cell at columnIndex and rowIndex.
AbstractDataType	getValueAt(int rowIndex, String columnKey) returns the value in the column with columnKey at rowIndex
boolean	isColumnAutoCreated() returns if the columns should be created automatically
void	removeColumn(String columnName) removes a column named with columnName
void	setColumnAt(TableColumn column, int columnIndex) sets the column
void	setColumnName(String columnName, int columnIndex) sets the name of the column.
void	setKeyColumn(int columnIndex) sets the column at columnIndex as the key column The columnIndex is the absolute index of the column in the TableViewModel, beginning with 1.
void	setValueAt(AbstractDataType aValue, int rowIndex, int columnIndex) sets the value at the rowIndex and columnIndex Note: since it's impossible to change the values in a jco table, a exception will be raised here.
