Constructor Detail

StringEscapeUtils

public StringEscapeUtils()

StringEscapeUtils instances should NOT be constructed in standard programming.

Instead, the class should be used as:

StringEscapeUtils.escapeJava("foo");

This constructor is public to permit tools that require a JavaBean instance to operate.

Method Detail

unescapeUnicode

public static String unescapeUnicode(String str)

Unescapes any Java literals found in the String. For example, it will turn a sequence of '\' and 'n' into a newline character, unless the '\' is preceded by another '\'.

Parameters:

str - the String to unescape, may be null

Returns:

a new unescaped String, null if null string input

unescapeUnicode

public static void unescapeUnicode(Writer out,
                                   String str)
                            throws IOException

Unescapes any Java literals found in the String to a Writer.

For example, it will turn a sequence of '\' and 'n' into a newline character, unless the '\' is preceded by another '\'.

A null string input has no effect.

Parameters:

out - the Writer used to output unescaped characters

str - the String to unescape, may be null

Throws:

IllegalArgumentException - if the Writer is null

IOException - if error occurs on underlying Writer
