Method Summary

void	cancelUncommittedRow(javax.swing.table.TableModel model) Removes the "fake" row from the model, effectively performing a cancel.
java.lang.Object[]	commitUncommittedRow(javax.swing.table.TableModel model) Commits the data in the row to the underlying model.
int	getAdjustedRowNumber(int row) Takes a row number (from the viewers perspective) and adjusts it based on whether a "fake" row had been added without being committed or cancelled.
static java.lang.Object[]	getDefaultRowValues(javax.swing.table.TableModel model) Gets the default values of a row as an object array for a given TableModel based upon a new instance of each column's class or null if the class is java.lang.Object.
int	getUncommittedRowNumber() Returns the index of the uncommitted row.
java.lang.Object	getValueAt(int columnIndex) Returns the value for the cell of the uncomitted row at columnIndex.
void	insertUncommittedRow(javax.swing.table.TableModel model, int row) Adds a "fake" row to the table model at the specified location.
boolean	isUncommittedRowPresent() Indicates whether an uncommitted row exists.
void	setValueAt(java.lang.Object value, int columnIndex) Sets the value in the cell of the uncommitted row at columnIndex to value.

isUncommittedRowPresent

public boolean isUncommittedRowPresent()

Indicates whether an uncommitted row exists.

Returns:

true if an uncommitted row exists

getUncommittedRowNumber

public int getUncommittedRowNumber()

Returns the index of the uncommitted row. Returns -1 if there is no uncommitted row.

Returns:

the index of the uncommitted row

getValueAt

public java.lang.Object getValueAt(int columnIndex)

Returns the value for the cell of the uncomitted row at columnIndex.

Parameters:

columnIndex - the column whose value is to be queried

                       int columnIndex)

Sets the value in the cell of the uncommitted row at columnIndex to value.

Parameters:

value - the new value

columnIndex - the column whose value is to be changed

getAdjustedRowNumber

public int getAdjustedRowNumber(int row)
