Method Detail

stringToUtf8Bytes

public static byte[] stringToUtf8Bytes(java.lang.String string)

Converts a string into its Java-style UTF-8 form. Java-style UTF-8 differs from normal UTF-8 in the handling of character '\0' and surrogate pairs.

Parameters:

string - non-null; the string to convert

Returns:

non-null; the UTF-8 bytes for it

utf8BytesToString

public static java.lang.String utf8BytesToString(byte[] bytes,
                                                 int start,
                                                 int length)

Converts an array of UTF-8 bytes into a string.

This method uses a global buffer to avoid having to allocate one every time, so it is *not* thread-safe

Parameters:

bytes - non-null; the bytes to convert

start - the start index of the utf8 string to convert

length - the length of the utf8 string to convert, not including any null-terminator that might be present

Returns:

non-null; the converted string

writeEscapedChar

public static void writeEscapedChar(java.io.Writer writer,
                                    char c)
                             throws java.io.IOException

Throws:

java.io.IOException

writeEscapedString

public static void writeEscapedString(java.io.Writer writer,
                                      java.lang.String value)
                               throws java.io.IOException

Throws:

java.io.IOException

escapeString

public static java.lang.String escapeString(java.lang.String value)
