Method Detail

addDirectoryToSkip

public void addDirectoryToSkip(String pattern)

Add a pattern that defines a directory to skip. We only need really simple patterns: just a single name that must match a component of a directory name exactly.

scan

public boolean scan(Scanner.Action action)
             throws IOException

Scan all files reachable from roots. Does a depth-first search. Ignores all directories (and their contents) that match an entry in patternsToSkip. Passes each file (not directories) to the action. If action returns false, scan terminates. The result of the scan is the result of the last action call.

Throws:

IOException
