GWT 2.x $entry function -

-

No developer information about this function can be found. I just know that wrapping jsni javascript calls for Java methods with this $ entry function has been suggested. I came to know that it catches the exception, so Java code can handle them. Is it all?

If you want to know what actually happens, then see com .google. Gwt.core.client.impl.Impl.entry (JavaScriptObject jsFunction) .

This function (at least in GWT 2.2.0) mainly calls entry0 (object jsFunction)

  • First of all, this is nothing Which is set by Scheduler.scheduleEntry () / li>
  • Then it ensures to execute jsFunction in an attempt block, to the exception To forward to GWT.getUncaughtExceptionHandler () , if there is such a handler.
  • Finally, this has been defined by any scheduler schedule ()

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
