Constructor Detail

HotLinkExpressionParser

public HotLinkExpressionParser(Object obj)
                        throws IOException

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

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

Throws:

IOException - if there are interop problems HotLinkExpressionParser theHotLinkExpressionParser = (HotLinkExpressionParser) obj;
