## Interface SerializableString

- All Known Implementing Classes:
    SerializedString

      public interface SerializableString

  Interface that defines how Jackson package can interact with efficient pre-serialized or lazily-serialized and reused String representations. Typically implementations store possible serialized version(s) so that serialization of String can be done more efficiently, especially when used multiple times.

  Note that "quoted" in methods means quoting of 'special' characters using JSON backlash notation (and not use of actual double quotes).

- - ### Method Detail

    - #### getValue

          String getValue()

      Returns unquoted String that this object represents (and offers serialized forms for)

    - #### charLength

          int charLength()

      Returns length of the (unquoted) String as characters. Functionally equivalent to:

             getValue().length();

    - #### asQuotedChars

          char[] asQuotedChars()

      Returns JSON quoted form of the String, as character array. Result can be embedded as-is in textual JSON as property name or JSON String.

    - #### asUnquotedUTF8

          byte[] asUnquotedUTF8()

      Returns UTF-8 encoded version of unquoted String. Functionally equivalent to (but more efficient than):

           getValue().getBytes("UTF-8");

    - #### asQuotedUTF8

          byte[] asQuotedUTF8()

      Returns UTF-8 encoded version of JSON-quoted String. Functionally equivalent to (but more efficient than):

           new String(asQuotedChars()).getBytes("UTF-8");

    - #### appendQuotedUTF8

          int appendQuotedUTF8(byte[] buffer,
                               int offset)

      Method that will append quoted UTF-8 bytes of this String into given buffer, if there is enough room; if not, returns -1. Functionally equivalent to:

            byte[] bytes = str.asQuotedUTF8();
            System.arraycopy(bytes, 0, buffer, offset, bytes.length);
            return bytes.length;

      Returns:
        Number of bytes appended, if successful, otherwise -1

    - #### appendQuoted

          int appendQuoted(char[] buffer,
                           int offset)

      Method that will append quoted characters of this String into given buffer. Functionally equivalent to:

            char[] ch = str.asQuotedChars();
            System.arraycopy(ch, 0, buffer, offset, ch.length);
            return ch.length;

      Returns:
        Number of characters appended, if successful, otherwise -1

    - #### appendUnquotedUTF8

          int appendUnquotedUTF8(byte[] buffer,
                                 int offset)

      Method that will append unquoted ('raw') UTF-8 bytes of this String into given buffer. Functionally equivalent to:

            byte[] bytes = str.asUnquotedUTF8();
            System.arraycopy(bytes, 0, buffer, offset, bytes.length);
            return bytes.length;

      Returns:
        Number of bytes appended, if successful, otherwise -1

    - #### appendUnquoted

          int appendUnquoted(char[] buffer,
                             int offset)

      Method that will append unquoted characters of this String into given buffer. Functionally equivalent to:

            char[] ch = str.getValue().toCharArray();
            System.arraycopy(bytes, 0, buffer, offset, ch.length);
            return ch.length;

      Returns:
        Number of characters appended, if successful, otherwise -1

    - #### writeQuotedUTF8

          int writeQuotedUTF8(OutputStream out)
                       throws IOException

      Returns:
        Number of bytes written
      Throws:
        `IOException`

    - #### writeUnquotedUTF8

          int writeUnquotedUTF8(OutputStream out)
                         throws IOException

      Returns:
        Number of bytes written
      Throws:
        `IOException`

    - #### putQuotedUTF8

          int putQuotedUTF8(ByteBuffer buffer)
                     throws IOException

      Returns:
        Number of bytes put, if successful, otherwise -1
      Throws:
        `IOException`

    - #### putUnquotedUTF8

          int putUnquotedUTF8(ByteBuffer out)
                       throws IOException

      Returns:
        Number of bytes put, if successful, otherwise -1
      Throws:
        `IOException`
