Class UpdateChecker

java.lang.Object

org.knime.core.eclipseUtil.UpdateChecker

public class UpdateChecker
extends Object

Checks for updates to new feature releases. The information is extract from a file "newRelease.txt" on the update site (e.g. http://www.knime.org/update/2.9/newRelease.txt). The contents of the file are as follow:

 http://www.knime.org/update/2.10   linux   x86_64   true   KNIME 2.10
 http://www.knime.org/update/2.10   macosx  x86      true   KNIME 2.10
 http://www.knime.org/update/2.10   win32   x86      false  KNIME 2.10
  ...
 

Each line contains a URL for a specific combination of OS and architecture. The boolean value indicates whether a direct update is possible or not. The last entry lists a name for the update. Note that the delimiter between the five columns must be a tab and not spaces. This also means the name must not contain tabs, only spaces.
