| /** |
| * Utility class for HTML form decoding. This class contains static methods |
| * for decoding a String from the <CODE>application/x-www-form-urlencoded</CODE> |
| * MIME format. |
| * <p> |
| * The conversion process is the reverse of that used by the URLEncoder class. It is assumed |
| * that all characters in the encoded string are one of the following: |
| * "{@code a}" through "{@code z}", |
| * "{@code A}" through "{@code Z}", |
| * "{@code 0}" through "{@code 9}", and |
| * "{@code -}", "{@code _}", |
| * "{@code .}", and "{@code *}". The |
| * character "{@code %}" is allowed but is interpreted |
| * as the start of a special escaped sequence. |
| * <p> |
| * The following rules are applied in the conversion: |
| * |
| * <ul> |
| * <li>The alphanumeric characters "{@code a}" through |
| * "{@code z}", "{@code A}" through |
| * "{@code Z}" and "{@code 0}" |
| * through "{@code 9}" remain the same. |
| * <li>The special characters "{@code .}", |
| * "{@code -}", "{@code *}", and |
| * "{@code _}" remain the same. |
| * <li>The plus sign "{@code +}" is converted into a |
| * space character " " . |
| * <li>A sequence of the form "<i>{@code %xy}</i>" will be |
| * treated as representing a byte where <i>xy</i> is the two-digit |
| * hexadecimal representation of the 8 bits. Then, all substrings |
| * that contain one or more of these byte sequences consecutively |
| * will be replaced by the character(s) whose encoding would result |
| * in those consecutive bytes. |
| * The encoding scheme used to decode these characters may be specified, |
| * or if unspecified, the default encoding of the platform will be used. |
| * </ul> |
| * <p> |
| * There are two possible ways in which this decoder could deal with |
| * illegal strings. It could either leave illegal characters alone or |
| * it could throw an {@link java.lang.IllegalArgumentException}. |
| * Which approach the decoder takes is left to the |
| * implementation. |
