示例1: FitsIntoExistingConstraintHierarchy
public bool FitsIntoExistingConstraintHierarchy(QCon constraint)
{
if (_field != null)
{
QField qf = constraint.GetField();
if (qf != null)
{
if (_field.Name() != null && !_field.Name().Equals(qf.Name()))
{
return false;
}
}
}
if (i_classMetadata == null || constraint.IsNullConstraint())
{
return true;
}
ClassMetadata classMetadata = constraint.GetYapClass();
if (classMetadata == null)
{
return false;
}
classMetadata = i_classMetadata.GetHigherOrCommonHierarchy(classMetadata);
if (classMetadata == null)
{
return false;
}
i_classMetadata = classMetadata;
return true;
}示例2: TryAddConstraint
// FIXME: This method should go completely.
// We changed the code to create the QCandidates graph in two steps:
// (1) call fitsIntoExistingConstraintHierarchy to determine whether
// or not we need more QCandidates objects
// (2) add all constraints
// This method tries to do both in one, which results in missing
// constraints. Not all are added to all QCandiates.
// Right methodology is in
// QQueryBase#createCandidateCollection
// and
// QQueryBase#createQCandidatesList
