Specify the classpath to use to load the Selector (nested element).- Returns:
- a classpath to be configured
-

-
verifySettings
public void verifySettings()These are errors specific to ExtendSelector only. If there are errors in the custom selector, it should throw a BuildException when isSelected() is called.- Overrides:
verifySettingsin classBaseSelector
-
isSelected
public boolean isSelected(java.io.File basedir, java.lang.String filename, java.io.File file) throws BuildExceptionAllows the custom selector to choose whether to select a file. This is also where the Parameters are passed to the custom selector, since we know we must have them all by now. And since we must know both classpath and classname, creating the class is deferred to here as well.- Specified by:
isSelectedin interfaceFileSelector- Specified by:
isSelectedin classBaseSelector- Parameters:
