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 Summary

int	appendQuoted(char[] buffer, int offset) Method that will append quoted characters of this String into given buffer.
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.
int	appendUnquoted(char[] buffer, int offset) Method that will append unquoted characters of this String into given buffer.
int	appendUnquotedUTF8(byte[] buffer, int offset) Method that will append unquoted ('raw') UTF-8 bytes of this String into given buffer.
char[]	asQuotedChars() Returns JSON quoted form of the String, as character array.
byte[]	asQuotedUTF8() Returns UTF-8 encoded version of JSON-quoted String.
byte[]	asUnquotedUTF8() Returns UTF-8 encoded version of unquoted String.
int	charLength() Returns length of the (unquoted) String as characters.
String	getValue() Returns unquoted String that this object represents (and offers serialized forms for)

int	putUnquotedUTF8(ByteBuffer out)
int	writeQuotedUTF8(OutputStream out)
int	writeUnquotedUTF8(OutputStream out)

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 equvalent 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
