Class DatatypeConverterImpl

java.lang.Object
  com.sun.xml.bind.DatatypeConverterImpl

All Implemented Interfaces:

DatatypeConverterInterface

public final class DatatypeConverterImpl
extends java.lang.Object
implements DatatypeConverterInterface

This class is the JAXB RI's default implementation of the DatatypeConverterInterface.

When client applications specify the use of the static print/parse methods in DatatypeConverter, it will delegate to this class.

This class is responsible for whitespace normalization.

installHook

public static java.lang.String installHook(java.lang.String s)

Just return the string passed as a parameter but installs an instance of this class as the DatatypeConverter implementation. Used from static fixed value initializers.

_parseBase64Binary

public static byte[] _parseBase64Binary(java.lang.String text)

Parameters:

text - base64Binary data is likely to be long, and decoding requires each character to be accessed twice (once for counting length, another for decoding.) A benchmark showed that taking String is faster, presumably because JIT can inline a lot of string access (with data of 1K chars, it was twice as fast)

encode

public static char encode(int i)

encodeByte

public static byte encodeByte(int i)

_printBase64Binary

public static java.lang.String _printBase64Binary(byte[] input)

_printBase64Binary

public static java.lang.String _printBase64Binary(byte[] input,
                                                  int offset,
                                                  int len)

_printBase64Binary

public static int _printBase64Binary(byte[] input,
                                     int offset,
                                     int len,
                                     char[] buf,
                                     int ptr)

Encodes a byte array into a char array by doing base64 encoding. The caller must supply a big enough buffer.

Returns:

the value of ptr+((len+2)/3)*4, which is the new offset in the output buffer where the further bytes should be placed.

_printBase64Binary

public static int _printBase64Binary(byte[] input,
                                     int offset,
                                     int len,
                                     byte[] out,
                                     int ptr)

Encodes a byte array into another byte array by first doing base64 encoding then encoding the result in ASCII. The caller must supply a big enough buffer.

Returns:

the value of ptr+((len+2)/3)*4, which is the new offset in the output buffer where the further bytes should be placed.
