  • All Known Implementing Classes:
    URLEncoderImpl
    public interface URLEncoder
    Service used to encode or decode strings that are placed into URLs. This is used as an alternative to UUEncoding. Alphabetics, numbers and some punctuation ("-", "_", ".", ":") are passed through as is, the "$" character is an escape, followed by either another "$", or by a four digit hex unicode number. A null input (not a blank input, but actual null) has a special encoding, "$N". Likewise, the blank string has the special encoding "$B".
