Thanks Dave, you're correct with the fall-through.
I've added "return| statements in the catch branches there.
However the compile-time error still persists:
1061: Call to a possibly undefined method inflate through
a reference with static type flash.utils:ByteArray.
I wonder why does compiler think, that _bytes is static?
Also if I remove the _bytes.inflate(), then the socket I/O works
ok, I can see the same amount of (deflated) bytes being read
as I send from my backend.
private function handleTcpData(event:ProgressEvent):void {
trace('handleTcpData: ' + event);
while (_socket.bytesAvailable > 0) {
if (_nbytes <= 0) {
if (_socket.bytesAvailable < 2) {
trace('Can not read short yet -
bytesAvailable='+
_socket.bytesAvailable);
return;
}
try {
_nbytes = _socket.readShort();
trace('Read _nbytes '+_nbytes);
} catch (e:Error) {
handleTcpError();
return;
}
} else {
if (_socket.bytesAvailable < _nbytes) {
trace('Can not read bytes yet -
bytesAvailable='+
_socket.bytesAvailable+' <
_nbytes='+_nbytes);
return;
}
try {
_socket.readBytes(_bytes, 0,
_nbytes);
trace('Read _bytes
'+_bytes.length);
} catch (e:Error) {
handleTcpError();
return;
}
}
try {
_bytes.inflate(); // this fails
} catch (error:IOError) {
trace('inflating failed');
}
trace(_bytes.length);
trace(_bytes);
//updateGUI(_bytes);
}
}
