ChildExpression

Class Overview

Represents an expression based on filtering children. This type of expression can be used to filter a parent by values on its children values. This filter results in a subquery on the parent's data source.
Example: This example performs this expression on PurchaseOrders: LinePrice = 100
where LinePrice is an attribute on the Line child of PurchaseOrder.

 DataObjectFactory factory = ...
 PurchaseOrderExpressionFilter poFilter = (PurchaseOrderExpressionFilter)factory.createDataObject(PurchaseOrderExpressionFilter.QUALIFIED_NAME);
 LineExpressionFilter LineFilter = (LineExpressionFilter)factory.createDataObject(LineExpressionFilter.QUALIFIED_NAME);
 LineFilter.addValueExpression("LinePrice", ValueExpression.EQUAL, new Number(100));
 poFilter.addChildExpression("Lines", lineFilter);
 DataCriteria dc = factory.createDataObject(DataCriteria.QUALIFIED_NAME);
 dc.setFilter(filter);
 List result = service.getDataList("PurchaseOrders", dc, null);
