Convert Vector to Tuple scala -

-

is possible convert vector of heterogeneous vectors list of tuple3 in scala

i.e. 

vector(vector(1,"a","b"),vector(2,"b","c")) list(tuple3(1,"a","b"),tuple3(2,"b","c"))

explicitly convert every inner vector tuple3:

vector.map {     case vector(f, s, t) => tuple3(f, s, t) }.tolist

if have vectors of variadic size can use more general approach:

def totuple(seq: seq[_]): product = {   val clz = class.forname("scala.tuple" + seq.size)   clz.getconstructors()(0).newinstance(seq.map(_.asinstanceof[anyref]): _*).asinstanceof[product] }  vector.map(totuple).tolist

but has restriction: max length of vectors 22.

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11...
