From source file:com.sina.cloudstorage.util.URLEncodedUtils.java

/**
 * Adds all parameters within the Scanner to the list of
 * <code>parameters</code>, as encoded by <code>encoding</code>. For
 * example, a scanner containing the string <code>a=1&b=2&c=3</code> would
 * add the {@link NameValuePair NameValuePairs} a=1, b=2, and c=3 to the
 * list of parameters.//  w w  w .java 2 s  .c o  m
 *
 * @param parameters
 *            List to add parameters to.
 * @param scanner
 *            Input that contains the parameters to parse.
 * @param charset
 *            Encoding to use when decoding the parameters.
