Method Detail

escapeJava

public static String escapeJava(String input)

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 and forward-slash (/) are escaped.

Example:

 input string: He didn't say, "Stop!"
 output string: He didn't say, \"Stop!\"
 

Parameters:

input - String to escape values in, may be null

Returns:

String with escaped values, null if null string input

unescapeJava

public static String unescapeJava(String input)

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:

input - the String to unescape, may be null

Returns:

a new unescaped String, null if null string input
