public class PathSplitter
extends Object

Splits a String representation path where elements are separated by defined or default ('/') separator. Leading and trailing separators are ignored. Empty elements are not ("/a//c/" as three elements, "a", "" and "c") This keeps an internal iterator, such that for an input of "/foo/bar/baz/a/b/c/d/e", following sequence of calls:

• skipTo(2) : return "baz"
• next() : return "a"
• remaining() : "b/c/d/e"

Method Detail

count

public int count()

Returns the number of path elements in the source string.

next

public String next()

Returns the next path element from the internal iterator.

skipTo

public String skipTo(int index)

Returns the element at the given 0-based index.

Throws:

ArrayIndexOutOfBoundsException

remaining

public String remaining()

Returns all the elements lefts after the last call to at() or next(), *without* a leading separator. This returns an empty string if there are not remaining elements. Calls to next(), skipTo() or remaining() after a call to remaining will lead to unexpected results.
