Interface IQueryBuilder

[contained in: com.sap.netweaver.bc.rf.par - bc.rf.common_api.jar]
public interface IQueryBuilder

Constructs IQueryExpressions for later use with the corresponding property search manager.

A IQueryBuilder constructs and combines IQueryExpressions, creating new IQueryExpressions, which finally are executed against the property search manager. Construction is done in the following way 

 builder.equ(x, y).and(builder.eq(z, "name")).or(builder.like(y, "%jpg"))

 builder.not(builder.greaterThan(x, new Integer(7)))
