Field Detail

ESCAPE_JAVA

public static final CharSequenceTranslator ESCAPE_JAVA

Translator object for escaping Java.

While escapeJava(String) is the expected method of use, this object allows the Java escaping functionality to be used as the foundation for a custom translator.

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

builder

public static StringEscapeUtils.Builder builder(CharSequenceTranslator translator)

Get a StringEscapeUtils.Builder.

Parameters:

translator - the text translator

Returns:

StringEscapeUtils.Builder

escapeJava

public static final 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
