Constructor Detail

SegmentGraph

public SegmentGraph()
             throws IOException,
                    UnknownHostException

Constructs a SegmentGraph using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

SegmentGraph

public SegmentGraph(Object obj)
             throws IOException

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

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

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

getCursor

public ISegmentGraphCursor getCursor(IPoint p)
                              throws IOException,
                                     AutomationException

Returns a SegmentGraphCursor initially located at the segment closest to the specified point.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

getCursor in interface ISegmentGraph

Parameters:

p - A reference to a com.esri.arcgis.geometry.IPoint (in)

Returns:

A reference to a com.esri.arcgis.geometry.ISegmentGraphCursor

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

load

public void load(IEnumGeometry geometries,
                 boolean generateFaces,
                 boolean takeOwnership)
          throws IOException,
                 AutomationException

Defines a SegmentGraph from an enumeration of polylines or polygons.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Sets the SegmentGraph to the empty state.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

setEmpty in interface ISegmentGraph

Throws:

IOException - If there are interop problems.
