IErrorFeatureContainer.ErrorFeatures Property

An enumeration of error features that match the passed in parameters.

[Visual Basic .NET]
Public Function get_ErrorFeatures ( _
    ByVal SpatialReference As ISpatialReference, _
    ByVal Rule As ITopologyRule, _
    ByVal Extent As IEnvelope, _
    ByVal Errors As Boolean, _
    ByVal Exceptions As Boolean _
) As IEnumTopologyErrorFeature

[C#]
public IEnumTopologyErrorFeature get_ErrorFeatures (
    ISpatialReference SpatialReference,
    ITopologyRule Rule,
    IEnvelope Extent,
    bool Errors,
    bool Exceptions
);

[C++]
HRESULT get_ErrorFeatures(
  ISpatialReference* SpatialReference,
  ITopologyRule* Rule,
  IEnvelope* Extent,
  VARIANT_BOOL Errors,
  VARIANT_BOOL Exceptions,
  IEnumTopologyErrorFeature** ErrorFeatures
);

[C++]
Parameters
SpatialReference [in]

  SpatialReference is a parameter of type ISpatialReference*
Rule [in]

  Rule is a parameter of type ITopologyRule*
Extent [in]

  Extent is a parameter of type IEnvelope*
Errors [in]

  Errors is a parameter of type bool
Exceptions [in]

  Exceptions is a parameter of type bool
ErrorFeatures [out, retval]

  ErrorFeatures is a parameter of type IEnumTopologyErrorFeature**

Product Availability

Errors Returned

ErrorFeatures will return an error if:

• False is specified for both Errors and Exceptions
• nothing is specified for Rule parameter

Remarks

ErrorFeatures will return an enumeration of error features belonging to the Topology Rule and within the Envelope that is supplied. The enumeration can contain Errors, errors marked as Exceptions or Both. To determine if a TopologyErrorFeature has been marked as an Exception, use the ITopologyErrorFeature::IsException property. If no error feature exists that matches the parameters, an empty enumeration is returned.

ErrorFeatures requires the spatial reference of the Topology, this can be obtained from the IGeoDataset interface.
