    public String interpreterCall(JspCompilationContext context, boolean isTagFile, String expression, Class<?> expectedType, String fnmapvar)
    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.
