Class Group

All Implemented Interfaces:
Serializable, Cloneable

public class Group extends Section
A report group. A group is a repeated section which is bound to an expression.

Default Behaviour

Whether a new group should be started is evaluated by the group's expression. If that expression returns Boolean.TRUE, a new group instance is started. (That expression answers the Questions: 'Does this group instance end here?').

If the group expression is invalid or there is no group expression at all, a group will consume all rows until the datasource is no longer advanceable.
