 class Path
extends Object

Stores a NVDL/NRL path information. Parses a path string and returns a list of Path objects. This stores a single path that can optionally start with a / and contains a list of local names separated by /, like /path1/path2 or path1/path2.

Nested Class Summary

(package private) static class

Path.ParseException Exception thrown in case we get errors parsing a path.

Field Summary

private static int	AFTER_SLASH After a slash.
private static int	IN_NAME In a local name.
private Vector	names The list of local names that form the path.
private boolean	root Flag indicating wether the path starts with / or not.
private static int	START Initial state.

Constructor Summary

Path(boolean root, Vector names)

root - Flag specifying wether the path starts with / or not.

names - The list of local names.

Method Detail

isRoot

boolean isRoot()

Determines if the path starts with / or not.

true if the path starts with /.

getNames

Vector getNames()

Get the local names list.

Returns:

A vector with the local names.

toString

public String toString()

Get a string representation of this path. It can be either /name1/name2 or name1/name2.

Overrides:

toString in class Object

parse

static Vector parse(String str)
             throws Path.ParseException

Gets the list of Path from the path string. The path string can represent more paths separated by |.

Parameters:

str - The path string.

Returns:

A Vector with the determined Path objects.

Throws:

Path.ParseException - In case of invalid path expression.

makeName

private static String makeName(String str,

                               int end)
                        throws Path.ParseException

Extracts a name from a given string (path) from the specified start position to the specified end position. It also checks that the extracted name is a valid non qualified name (local name).

Parameters:

str - The path string.

start - The start position.

end - The end position.

Returns:

A string representing the extracted local name.

Throws:

Path.ParseException - In case of invalid local name.

main

public static void main(String[] args)
                 throws Path.ParseException

Main method, for test.
