      • specialText

        public static java.lang.String specialText​(Token t)
        Deprecated.
        use getSpecialText(Token t)

      • getSpecialText

        public static org.apache.commons.lang.text.StrBuilder getSpecialText​(Token t)
        Collect all the s that are carried along with a token. Special tokens do not participate in parsing but can still trigger certain lexical actions. In some cases you may want to retrieve these special tokens, this is simply a way to extract them.
        Parameters:
        t - the Token
        Returns:
        StrBuilder with the special tokens.

      • tokenLiteral

        public static java.lang.String tokenLiteral​(Token t)
        complete node literal
        Parameters:
        t -
        Returns:
        A node literal.

      • interpolate

        public static java.lang.String interpolate​(java.lang.String argStr,
                                           Context vars)
                                    throws MethodInvocationException
        Deprecated.
        this method isn't called by any class
        Utility method to interpolate context variables into string literals. So that the following will work: #set $name = "candy" $image.getURI("${name}.jpg") And the string literal argument will be transformed into "candy.jpg" before the method is executed.
        Parameters:
        argStr -
        vars -
        Returns:
        Interpoliation result.
        Throws:
        MethodInvocationException
