Class UrlConverter

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

All Implemented Interfaces:

ObjectConverter

public class UrlConverter

extends java.lang.Object

implements ObjectConverter

Converts the given object into a String via the toString() method and then converts the String into a java.net.URL object.

The string is expected to be in URL format so that a call to the constructor for java.net.URL succeeds wihtout a MalformedURLException. The exception to this is a custom "resource" string to get a URL from a Class resource. The format for this type of String should be as follows:

resource:com.package.ClassName!/filedir/filename.gif

Nothing is done with the resulting URL in terms of connecting to it. So while the converter will return a URL object, connecting to it might still have problems.
