Class TinNodeEnumerator

java.lang.Object
  com.esri.arcgis.geodatabase.TinNodeEnumerator

All Implemented Interfaces:

IEnumTinElement, IEnumTinNode, com.esri.arcgis.interop.RemoteObjRef, ISupportErrorInfo, Serializable

public class TinNodeEnumerator
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IEnumTinElement, IEnumTinNode, ISupportErrorInfo

The Esri TinNodeEnumerator component.

Description

The TinNodeEnumerator object is used for iterative TinNode processing on TINs. For example, to return all nodes within the interpolation zone (domain) of a TIN or the nodes of a TinPolyline. TinFilters, like TinValueFilter and TinDataElementFilter are used to control which nodes are passed back by the enumerator. Custom, application specific, filters can be used as well.

The TinNodeEnumerator object isn't co-creatable. Other functions are used to create it. Tin, TinPolyline, and TinPolygon objects can create and return TinNodeEnumerators.

Constructor Detail

TinNodeEnumerator

public TinNodeEnumerator(Object obj)
                  throws IOException

Construct a TinNodeEnumerator using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to TinNodeEnumerator.
Casting to this class from the return value of a method will not work, as this class represents an abstract class in ArcObjects.
*
TinNodeEnumerator o = (TinNodeEnumerator)obj; // will not work

TinNodeEnumerator o = new TinNodeEnumerator(obj); // Use this constructor instead
* @param obj an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems TinNodeEnumerator theTinNodeEnumerator = (TinNodeEnumerator) obj;
