DataColumn |
DataRelation.getChildColumn()
|
DataColumn |
DataTable.getColumn(java.lang.String colName)
|
DataColumn |
DataRelationTable.getColumn(java.lang.String colName)

DataRow.addCell(DataColumn col)
Used internally to add a cell to the row. |
protected org.jdesktop.dataset.DataRow.DataCell |
DataRow.getCell(DataColumn col)
Returns the DataCell for the column; if there is none, creates one initialized to the column's default value. |
java.util.Comparator |
DataTable.getColumnComparator(DataColumn col)
Returns a Comparator bound to a given Column. |
java.lang.Object |
DataRow.getOriginalValue(DataColumn col)
Deprecated. use getReferenceValue(DataColumn col) |
java.lang.Object |
DataRow.getReferenceValue(DataColumn col)
Returns the reference value for the column. |
java.lang.Object |
DataRow.getValue(DataColumn col)
Returns the current value for the column. |
java.lang.Object |
DataTable.getValue(DataRow row,
DataColumn col)
Retrieves the current value for the given row and column. |
boolean |
DataTable.hasColumnComparator(DataColumn col)
Returns true if the column has a specific comparator assigned to it; with DataTable.setColumnComparator(DataColumn, Comparator) ; see class
JavaDocs, and docs for DataRow . |
boolean |
DataRow.isModified(DataColumn col)
Returns true if the current value for the column is different from its reference value. |
void |
DataTable.removeColumnComparator(DataColumn col)
Removes the specific Comparator assigned to the column, if any; fails silently if none assigned; see class JavaDocs, and docs for DataRow . |
void |
DataRow.resetToReferenceValue(DataColumn col)
Resets the DataColumn in the row to its reference value, effectively reverting the effects of calling DataRow.setValue(DataColumn, Object) till now. |
void |
DataRelation.setChildColumn(DataColumn childColumn)
sets the child DataColumn in this parent/child relation |
void |
DataTable.setColumnComparator(DataColumn col,
java.util.Comparator comp)

void |
DataRow.setValue(DataColumn col,
java.lang.Object value)
Sets the given value to the specified DataColumn with the given name. |
