Calculates the number of times that this tokenizer's nextToken method can be called before it generates an exception.

Usage

From source file:Main.java

private static String getPathBeforeLastInPathElement(String path) {
    StringTokenizer st = new StringTokenizer(path, ".");
    StringBuffer sb = new StringBuffer();
    int cpt = st.countTokens();
    //      if (cpt==1)
    //         return root;
    int i = cpt - 1;
    for (int j = 0; j < i; j++) {
        String token = st.nextToken();
        sb.append(token);/*from w ww . jav a 2s . c  om*/
        if (j != i - 1)
            sb.append(".");
    }

    //      String last = getLastInPathElement(path);
    //      path = StringUtils.substringBefore(path, last);
