org.eclipse.birt.report.model.api.JoinConditionHandle
Represents a handle of condition used for joint dataset. The joint dataset is
dataset joined by several normal datasets on join conditions.
Each join condition has following properties:
- Join Type
- the join type of the join condition which can be inner join, left out join and right out join.
- Operator
- the join condition's comparison operator
- Left Dataset
- the left dataset of the join condition.
- Right Dataset
- the right dataset of the join condition.
- Left Expression
- the left expression of the join condition.
- Right Expression
- the right expression of the join condition.
