Class CriteriaAdapterImpl

java.lang.Object
  oracle.jbo.common.CommonCriteriaAdapter
      oracle.jbo.server.CriteriaAdapterImpl

All Implemented Interfaces:

CriteriaAdapter, ViewCriteriaAdapter

Direct Known Subclasses:

BaseSQLBuilderImpl

public class CriteriaAdapterImpl
extends CommonCriteriaAdapter
implements ViewCriteriaAdapter

This class provides a concrete implementation of a CriteriaAdapter interface to be used on the server side of the framework. Users looking to override the criteria clause generation behavior should extend this class and pass a reference of that class to ViewObjectImpl.setViewCriteriaAdapter(ViewCriteriaAdapter) method and override the methods CommonCriteriaAdapter.getCriteriaClause(oracle.jbo.ViewCriteria) or CommonCriteriaAdapter.getCriteriaClause(oracle.jbo.AttributeDef[], oracle.jbo.ViewCriteria).

Parameters:

criteria - The view criteria that we are building the where clause for

criteriaClause - The where clause that has been generated

Returns:

The where clause to be used by the statement
