public SubSetTableModel(int start, int end, javax.swing.table.TableModel model)
start
must be a positive integer and
denotes the number or rows removed from the start of the tablemodel. end
is the number of the last translated row. Any row after end
is ignored.
End must be greater or equal the given start row.

- the number of rows that should be removed.end
- the last row.model
- the wrapped model
java.lang.NullPointerException
- if the given model is null
java.lang.IllegalArgumentException
- if start or end are invalid.Method Detail |

public int getRowCount()
JTable
uses this method to
determine how many rows it should display. This method should be quick, as it is
called frequently during rendering.
