Class GlobalClassCreator

java.lang.Object
  org.knime.core.eclipseUtil.GlobalClassCreator

Deprecated. Since 2.4 the KNIME core is using the Eclipse Buddy-Classloading mechanism. So the workaround via the GlobalClassCreator is not necessary any more.

@Deprecated
public final class GlobalClassCreator
extends Object

Eclipse workaround to create new Classes through one, global gateway. We can now plugin an Eclipse hack that knows about all plugins and can create classes using the appropriate class loader. If no creator is specified the usual Java class loader will be used.

Method Detail

addClassReplacementPair

public static void addClassReplacementPair(String oldClassName,
                                           String replacedClassName)

Deprecated.

Adds a replacement string for obsolete class names. This is used primarily by data cell class implementations, which were moved from specific vendor plugins to KNIME core (mostly in a org.knime.chem.types). The replaced class is supposed to use the same internals (e.g. a similar persistor) as the replacing class.

This method is not intended for public use; if you want to replace an obsolete class by a KNIME core class, contact the KNIME team.

Parameters:

oldClassName - The old, to be replaced class

replacedClassName - The new class replacing oldClassName

Throws:

NullPointerException - If either argument is null

IllegalStateException - If there is already an entry for the old class name.

createClass

public static Class<?> createClass(String className)
                            throws ClassNotFoundException

Deprecated.

return Class specified name - using either normal classloader or special one if it was given before.

Parameters:

className - qualified class name

Returns:

Class of specified name

Throws:

ClassNotFoundException - Class not found.
