                               String expression,

      Description copied from interface: `ELInterpreter`
      Returns the string representing the code that will be inserted into the servlet generated for JSP. The default implementation creates a call to `PageContextImpl.proprietaryEvaluate( String, Class, javax.servlet.jsp.PageContext, org.apache.jasper.runtime.ProtectedFunctionMapper)` but other implementations may produce more optimised code.
      Specified by:
        `interpreterCall` in interface `ELInterpreter`
      Parameters:
        `context` - The compilation context
        `isTagFile` - `true` if in a tag file rather than a JSP
        `expression` - a String containing zero or more "${}" expressions
        `expectedType` - the expected type of the interpreted result
        `fnmapvar` - Variable pointing to a function map.
      Returns:
        a String representing a call to the EL interpreter.
