NewLineFeedback

public NewLineFeedback()
                throws java.io.IOException,
                       java.net.UnknownHostException

Constructs a NewLineFeedback using ArcGIS Engine.

Throws:

java.io.IOException - if there are interop problems

NewLineFeedback

public NewLineFeedback(java.lang.Object obj)
                throws java.io.IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.

Construct a NewLineFeedback using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to NewLineFeedback.
NewLineFeedback theNewLineFeedback = (NewLineFeedback) obj;
