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.

public static String escapeJava(String str)
Escapes the characters in a String using Java String rules.
Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)
So a tab becomes the characters '\\' and
't'.
The only difference between Java strings and JavaScript strings is that in JavaScript, a single quote must be escaped.
Example:
input string: He didn't say, "Stop!" output string: He didn't say, \"Stop!\"
str - String to escape values in, may be nullnull if null string input
public static void escapeJava(Writer out, String str)
Escapes the characters in a String using Java String rules to
a Writer.
A null string input has no effect.
nullout - Writer to write escaped string intostr - String to escape values in, may be null
public static String escapeJavaScript(String str)
Escapes the characters in a String using JavaScript String rules.
Escapes any values it finds into their JavaScript String form. Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)
So a tab becomes the characters '\\' and
't'.
The only difference between Java strings and JavaScript strings is that in JavaScript, a single quote must be escaped.
Example:
input string: He didn't say, "Stop!" output string: He didn\'t say, \"Stop!\"
str - String to escape values in, may be nullnull if null string input
public static void escapeJavaScript(Writer out, String str)
Escapes the characters in a String using JavaScript String rules
to a Writer.
A null string input has no effect.
nullout - Writer to write escaped string intostr - String to escape values in, may be null
public static String unescapeJava(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 '\'.
str - the String to unescape, may be nullString, null if null string input
public static void unescapeJava(Writer out, String str)
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.
nullout - the Writer used to output unescaped charactersstr - the String to unescape, may be null
public static String unescapeJavaScript(String str)
Unescapes any JavaScript 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
'\'.
str - the String to unescape, may be nullString, null if null string input
public static void unescapeJavaScript(Writer out, String str)
Unescapes any JavaScript literals found in the String to a

into a newline character, unless the '\' is preceded by another
'\'.
