Examples of groovy.lang.GroovyClassLoader

groovy.lang.GroovyClassLoader
A ClassLoader which can load Groovy classes. The loaded classes are cached, classes from other classlaoders should not be cached. To be able to load a script that was asked for earlier but was created later it is essential not to keep anything like a "class not found" information for that class name. This includes possible parent loaders. Classes that are not chached are always reloaded. @author James Strachan @author Guillaume Laforge @author Steve Goetze @author Bing Ran @author Scott Stirling @author Jochen Theodorou @version $Revision: 13282 $
