Class DirectoryMetaSnapshot

java.lang.Object

com.aoindustries.io.DirectoryMetaSnapshot

public final class DirectoryMetaSnapshot
extends Object

Recursively (but not following symbolic links), gets a snapshot of the meta data for a directory. To see if any file has been modified, this meta data may be compared to a snapshot of the same directory at a different time. To perform a quick comparison of two directory trees, a snapshot may be compared to a snapshot of a different directory. Only watches the lengths and modified times for filesystem objects that Java considers a file.
