public class TinDataElementFilter
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, ITinFilter, ISupportErrorInfo

The ESRI TinDataElementFilter component.

Description

The TinDataElementFilter is used to filter nodes, edges, and triangles based on whether they are within the interpolation zone, or data area, of the TIN.

TIN elements (nodes, edges, triangles) can exist inside or outside the TIN's data area. When TINs are built from points or breaklines the data area is a convex hull that includes all user entered data. The only elements that are 'outside' are the four supernodes and their incident edges and triangles. If clip or erase polygons are added to the TIN they further modify what is considered to be 'inside'. This occurs through triangle masking. See TinTriangle for more information on masking and data area delineation.

The TinDataElementFilter is typically used with a TIN element enumerator (e.g. TinNodeEnumerator) to return either those elements that are inside the TIN's data area, or all elements. This is the most basic TIN element filter. It implements ITinFilter. Use this filter when you're only concerned about inside vs. outside. Other TIN filters implement interfaces which inherit from ITinFilter and therefore can filter on this plus additional properties.

Constructor Detail

TinDataElementFilter

public TinDataElementFilter()
                     throws IOException,
                            UnknownHostException

Constructs a TinDataElementFilter using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

TinDataElementFilter

public TinDataElementFilter(Object obj)
                     throws IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
TinDataElementFilter theTinDataElementFilter = (TinDataElementFilter) obj;

Construct a TinDataElementFilter using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to TinDataElementFilter.

Parameters:

obj - an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems

Method Detail

getClsid

public static String getClsid()

getClsid.

equals

public boolean equals(Object o)

Compare this object with another

Overrides:

equals in class Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class Object

canPass

public boolean canPass(ITinElement pElement)
                throws IOException,
