removeListener

Object removeListener

YAHOO.ext.grid.AbstractDataModel

YAHOO.ext.grid.AbstractDataModel()

fireCellUpdated

void fireCellUpdated(row, col)

Notifies listeners that the value of the cell at [row, col] has been updated

fireRowsDeleted

void fireRowsDeleted(firstRow, lastRow)

Notifies listeners that rows in the range [firstRow, lastRow], inclusive, have been deleted

fireRowsInserted

void fireRowsInserted(firstRow, lastRow)

Notifies listeners that rows in the range [firstRow, lastRow], inclusive, have been inserted

fireRowsSorted

void fireRowsSorted(sortColumnIndex, sortDir, noRefresh)

Notifies listeners that rows have been sorted and any indexes may be invalid

fireRowsUpdated

void fireRowsUpdated(firstRow, lastRow)

Notifies listeners that rows in the range [firstRow, lastRow], inclusive, have been updated

fireTableDataChanged

void fireTableDataChanged()

Notifies listeners that all data for the grid may have changed - use as a last resort. This also wipes out all selections a user might have made.

getRowCount

void getRowCount()

Empty interface method - Classes which extend AbstractDataModel should implement this method. See YAHOO.ext.DefaultDataModel for an example implementation.

getRowId

void getRowId(rowIndex)

Empty interface method - Classes which extend AbstractDataModel should implement this method. See YAHOO.ext.DefaultDataModel for an example implementation.

getSortState

Object getSortState()

Interface method to supply the view with info regarding the Grid's current sort state - if overridden, this should return an object like this {YAHOO.ext.grid.AbstractDataModel.prototype.column = this;.sortColumn, YAHOO.ext.grid.AbstractDataModel.prototype.direction = this;.sortDir}.

getTotalRowCount

Object getTotalRowCount()

Empty interface method - Classes which extend AbstractDataModel should implement this method to support virtual row counts.

getValueAt

void getValueAt(rowIndex, colIndex)

Empty interface method - Classes which extend AbstractDataModel should implement this method. See YAHOO.ext.DefaultDataModel for an example implementation.

isPaged

Object isPaged()

setValueAt

void setValueAt(value, rowIndex, colIndex)

Empty interface method - Classes which extend AbstractDataModel should implement this method. See YAHOO.ext.DefaultDataModel for an example implementation.

sort

void sort(columnModel, columnIndex, direction, suppressEvent)

Empty interface method - Classes which extend AbstractDataModel should implement this method. See YAHOO.ext.DefaultDataModel for an example implementation.
