Class PresentSelector

All Implemented Interfaces:
Cloneable, ResourceSelector, FileSelector

public class PresentSelector extends BaseSelector
Selector that filters files based on whether they appear in another directory tree. It can contain a mapper element, so isn't available as an ExtendSelector (since those parameters can't hold other elements).

    • setPresent

      public void setPresent(PresentSelector.FilePresence fp)
      This sets whether to select a file if its dest file is present. It could be a negate boolean, but by doing things this way, we get some documentation on how the system works. A user looking at the documentation should clearly understand that the ONLY files whose presence is being tested are those that already exist in the source directory, hence the lack of a destonly option.
      fp - An attribute set to either srconly or both.
    • verifySettings

      public void verifySettings()
      Checks to make sure all settings are kosher. In this case, it means that the targetdir attribute has been set and we have a mapper.
      verifySettings in class BaseSelector
    • isSelected

      public boolean isSelected(File basedir, String filename, File file)
      The heart of the matter. This is where the selector gets to decide on the inclusion of a file in a particular fileset.
      Specified by:
      isSelected in interface FileSelector
      Specified by:
      isSelected in class BaseSelector
      basedir - the base directory the scan is being done from
      filename - is the name of the file to check
      file - is a object the selector can use
      whether the file should be selected or not
