Class ConverterImageIcon

java.lang.Object
  com.abstractics.utils.converter.ConverterImageIcon

All Implemented Interfaces:

ObjectConverter

public class ConverterImageIcon

extends java.lang.Object

implements ObjectConverter

Converts the given object into a String via the toString() method and then converts the String into a javax.swing.ImageIcon object.

The string is expected to be a URL pointing to a valid image resource. Any valid URL format is supported (http, file, jar, etc.) The URL is used to call the ImageIcon constructor that takes a URL as a parameter. An instance of UrlConverter is used to handle the URL conversion, so any valid URL pattern for that converter will work.

If the image cannot be loaded, then an ObjectConverterException is thrown.
