public class PresentSelector
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).

public java.lang.String toString()

targetdir - the directory to scan looking for matching files.
public Mapper createMapper()
throws BuildException
BuildException - if more that one mapper definedpublic void setPresent(PresentSelector.FilePresence fp)
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 srconlyboth.public void verifySettings()

public boolean isSelected(java.io.File basedir,
java.lang.String filename,
java.io.File file)
isSelected in interface FileSelectorisSelected in class BaseSelectorbasedir - the base directory the scan is being done fromfilename - is the name of the file to checkfile - is a java.io.File object the selector can use
