Usage

From source file:org.openfaces.component.table.impl.TableDataModel.java

public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
    groupingRules = (List<GroupingRule>) in.readObject();
    sortingRules = (List<SortingRule>) in.readObject();
    rowKeyExpression = ValueBindings.readValueExpression(in);
    rowDataByKeyExpression = ValueBindings.readValueExpression(in);
    pageSize = in.readInt();
    pageIndex = in.readInt();/*w w w .ja v  a  2  s  . c o  m*/
    setWrappedData(null);

    // restoring old extracted row keys is needed for correct restoreRows/restoreRowIndexes functionality, which
    // in turn is required for correct data submission in case of concurrent data modifications
    extractedRowKeys = (List) in.readObject();
