net.sourceforge.squirrel_sql.fw.util.FileWrapper
An interface that abstracts the java.io.File interface, so that the actual implementation can vary. Since java.io.File is a class, it is not easy to write tests for code that deals with Files without having those files actually exist on the filesystem. Since filesystems are OS-specific, this tends to make those tests non-portable. This is my attempt to alleviate this issue. The companion class that implements this interface in FileWrapperImpl, and it can be used to wrap an actual java.io.File, delegating method calls to the underlying File. @author manningr
