Method Detail

normalize

public static URI normalize(URI uri,
                            boolean preserveContdSlashes)

Normalize the URI provided and return the normalized copy.

Parameters:

uri - The URI to normalize

preserveContdSlashes - Shall we preserve "///" slashes

Returns:

New normalized URI

removeDotSegments

public static String removeDotSegments(String path,
                                       boolean preserveContdSlashes)

Remove dots from path. alg taken from http://gbiv.com/protocols/uri/rfc/rfc3986.html#relative-dot-segments the alg works as follows: 1. The input buffer is initialized with the now-appended path components and the output buffer is initialized to the empty string. 2. While the input buffer is not empty, loop as follows: A. If the input buffer begins with a prefix of "../" or "./", then remove that prefix from the input buffer; otherwise, B. if the input buffer begins with a prefix of "/./" or "/.", where "." is a complete path segment, then replace that prefix with "/" in the input buffer; otherwise, C. if the input buffer begins with a prefix of "/../" or "/..", where ".." is a complete path segment, then replace that prefix with "/" in the input buffer and remove the last segment and its preceding "/" (if any) from the output buffer; otherwise, D. if the input buffer consists only of "." or "..", then remove that from the input buffer; otherwise, E. move the first path segment in the input buffer to the end of the output buffer, including the initial "/" character (if any) and any subsequent characters up to, but not including, the next "/" character or the end of the input buffer. 3. Finally, the output buffer is returned as the result of remove_dot_segments.

Parameters:

path - Path provided

preserveContdSlashes - Shall we preserve "///" slashes

Returns:

New path
