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 null
null
if null string inputpublic static void escapeJava(Writer out, String str) throws IOException
Escapes the characters in a String
using Java String rules to
a Writer
.
A null
string input has no effect.

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.

public static String unescapeJava(String str)

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