SerializableString (jackson-core 2.15.2)

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).

  - getValue
```
String getValue()
```
    Returns unquoted String that this object represents (and offers serialized forms for)
    
    Returns:
    
    Unquoted String
  - charLength
```
int charLength()
```
    Returns length of the (unquoted) String as characters. Functionally equivalent to:
```
   getValue().length();
```
    Returns:
    
    Length of the String in characters
  - 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.
    
    Returns:
    
    JSON quoted form of the String as char[]
  - asUnquotedUTF8
```
byte[] asUnquotedUTF8()
```
    Returns UTF-8 encoded version of unquoted String. Functionally equivalent to (but more efficient than):
```
 getValue().getBytes("UTF-8");
```
    Returns:
    
    UTF-8 encoded version of String, without any escaping
  - 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");
```
    Returns:
    
    UTF-8 encoded version of JSON-escaped String
  - 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;
```
    Parameters:
    
    buffer - Buffer to append JSON-escaped String into
    
    offset - Offset in buffer to append String at
    
    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;
```
    Parameters:
    
    buffer - Buffer to append JSON-escaped String into
    
    offset - Offset in buffer to append String at
    
    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;
```
    Parameters:
    
    buffer - Buffer to append literal (unescaped) String into
    
    offset - Offset in buffer to append String at
    
    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;
```
    Parameters:
    
    buffer - Buffer to append literal (unescaped) String into
    
    offset - Offset in buffer to append String at
    
    Returns:
    
    Number of characters appended, if successful, otherwise -1

    IOException - if underlying stream write fails
  - writeUnquotedUTF8
```
int writeUnquotedUTF8(OutputStream out)

    Number of bytes written
    
    Throws:
    
    IOException - if underlying stream write fails
  - putQuotedUTF8
```
int putQuotedUTF8(ByteBuffer buffer)
           throws IOException
```
    Method for appending JSON-escaped UTF-8 encoded String value into given ByteBuffer, if it fits.
