Paths.Normalizer

public Paths.Normalizer(char separatorChar)

normalize

public String normalize(String path)

Removes all redundant separators, dot directories (".") and dot-dot directories ("..") from the given path name and returns the result. If present, a single trailing separator character is retained, except after a dot-dot directory which couldn't get erased. A resulting single dot-directory is truncated to an empty path.

On Windows, a path may be prefixed by a drive letter followed by a colon. On all platforms, a path may be prefixed by two leading separators to indicate a UNC, although this is currently only supported on Windows.

Parameters:

path - the non-null path name to normalize.

Returns:

path if it was already in normalized form. Otherwise, a new string with the normalized form of the given path name.

normalize

private int normalize(int collapse,
                      int end)

This is a recursive call: The top level call should provide 0 as the skip parameter, the length of the path as the end parameter and an empty string buffer as the result parameter.

Parameters:

collapse - the number of adjacent dir/.. segments in the path to collapse. This value must not be negative.

end - the current position in path. Only the string to the left of this index is considered. If not positive, nothing happens.

Returns:

The number of adjacent segments in the path which have not been collapsed at this position.
