Class InItemGroupState

java.lang.Object
  org.jfree.report.states.ReportState
      org.jfree.report.states.InItemGroupState

All Implemented Interfaces:

java.lang.Cloneable

public final class InItemGroupState

extends ReportState

Prints the itemBand. Before the band is printed, the items are advanced and the next data row gets activated. Before any row has been read, the currentItem state is BEFORE_FIRST_ITEM, comparable to ResultSet.isBeforeFirst () in java.sql.ResultSet. After the item has advanced the elements are populated and an itemsAdvancedEvent is fired.

If the activated Item is the last item in its group, the next state will be an PostItemGroupHeader. In the other case, the current state remains this ItemsAdvanced state.
