generics - TypeScript type parameter to implement multiple interfaces -

-

in c#, can this:

class dictionary<tkey, tval> tkey : icomparable, ienumerable { }

is there way in typescript 1.5 beta type parameter in generic class or function implement multiple interfaces, without creating entirely new interface purpose?

the obvious way not working due ambiguity of commas. 

class dictionary<tkey extends icomparable, ienumerable, tvalue> { }

by way, funnily enough, extends can handle interface unions fine in generics:

class dictionary<tkey extends icomparable|ienumerable, tvalue> { }

intersection types here since ts 1.6 , can use in above example:

class dictionary<tkey extends icomparable & ienumerable, tvalue> { }

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*...
