casting - java unchecked cast required: Class<A> found: Class<CAP#1> where CAP#1 is a fresh type-variable -

-

i trying rid of compiler warnings in code, , 1 little frustrating.

i need functional operations class object of particular class i've created. let's illustrate code:

public static void main(string[] args) {     obj = getobj();     class<a> clazz = obj.getclass(); }  static class {}  static getobj() {     return new a(); }

this code throws compiler error:

incompatible types: class<cap#1> cannot converted class<a>   cap#1 fresh type-variable:     cap#1 extends capture of ? extends

ok, cast obj getclass():

class<a> clazz = (class<a>)obj.getclass();

and warning (better error):

[unchecked] unchecked cast   required: class<a>   found:    class<cap#1>   cap#1 fresh type-variable:     cap#1 extends capture of ? extends

so, how check class cast?

tried this:

class c = obj.getclass(); class<a> clazz = c instanceof class<a> ? (class<a>)c : null;

but produced warning , error.

so i'm stumped.

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
