Class EscapeCharacters

  gr.uoa.di.madgik.searchlibrary.operatorlibrary.google.util.EscapeCharacters

public final class EscapeCharacters
extends Object

Convenience methods for escaping special characters related to HTML, XML, and regular expressions.

To keep you safe by default, WEB4J goes to some effort to escape characters in your data when appropriate, such that you usually don't need to think too much about escaping special characters. Thus, you shouldn't need to directly use the services of this class very often.

For Model Objects containing free form user input, it is highly recommended that you use SafeText, not String. Free form user input is open to malicious use, such as Cross Site Scripting attacks. Using SafeText will protect you from such attacks, by always escaping special characters automatically in its toString() method.

The following WEB4J classes will automatically escape special characters for you, when needed :

• the SafeText class, used as a building block class for your application's Model Objects, for modeling all free form user input
• the Populate tag used with forms
• the Report class used for creating quick reports
• the Text, TextFlow, and Tooltips custom tags used for translation
