com.google.common.escape.CharEscaper

An object that converts literal text into a format safe for inclusion in a particular context (such as an XML document). Typically (but not always), the inverse process of "unescaping" the text is performed automatically by the relevant parser.

For example, an XML escaper would convert the literal string {@code "Foo"} into {@code "Foo<Bar>"} to prevent {@code ""} from being confused with an XML tag. When theresulting XML document is parsed, the parser API will return this text as the original literal string {@code "Foo"}.

A {@code CharEscaper} instance is required to be stateless, and safe when used concurrently bymultiple threads.

Several popular escapers are defined as constants in classes like {@link com.google.common.html.HtmlEscapers}, {@link com.google.common.xml.XmlEscapers}, and {@link SourceCodeEscapers}. To create your own escapers extend this class and implement the {@link #escape(char)} method. @author Sven Mawson @since 15.0
