The ESRI TinPolyline component.

Description

A TinPolyline is a linear feature embedded in a triangulation. It is defined by a set of connected edges that share like properties. These properties are set using one of the TinFilters. Edges that have properties compatible with the filter are considered part of the set. TinPolyline objects are created via ITinAdvanced.ExtractPolyline.

Different types of filters can be used to define a TinPolyline. Some are provided by 3D Analyst. Others can be custom made. Stock filters that support TinPolyline definition include TinEdgeTypeFilter and TinValueFilter.

In addition to a filter, a TinPolyline needs a starting location which is specified using a seed edge. The seed and filter are used together to dynamically discover a polyline. The seed can exist anywhere along the polyline. When the software extracts a TinPolyline it starts with the seed and uses the TIN's topology to search outward. An edge incident to the seed that passes through the filter is added to the set. Its neighbors are examined in turn. This continues iteratively until no more edges are found. Junctures exist at nodes where more than two edges with the appropriate filter properties come together. Junctures represent locations where two or more TinPolylines meet. The iterative search process does not pass through junctures.

Constructor Detail

TinPolyline

public TinPolyline(Object obj)
            throws IOException

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

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

Throws:

IOException - if there are interop problems TinPolyline theTinPolyline = (TinPolyline) obj;

Method Detail

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
