Syntax
class StatelessConnectHandlerComponent : public HandlerComponent
Remarks
PacketHandler component for implementing a stateless (non-memory-consuming) connection handshake
Partially based on the Datagram Transport Layer Security protocol.
Constructors

|---|---|---|---|
 |
Base constructor |
Functions
| Type | Name | Description | |
|---|---|---|---|
  |
bool | DoesRestartedHandshakeMatch
(
StatelessConnectHandlerComponent& NetConnComponent |
When a restarted handshake is completed, this is used to match it up with the existing NetConnection |
  |
void | GetChallengeSequence
(
int32& OutServerSequence, |
Used for retrieving the initial packet sequence values from the handshake data, after a successful challenge |
  |
bool | HasPassedChallenge
(
const TSharedPtr< const FInternetAddr >& Address, |
Whether or not the specified connection address, has just passed the connection handshake challenge. |
 |
void | InitFromConnectionless
(
StatelessConnectHandlerComponent* InConnectionlessHandler |
Initializes a serverside UNetConnection-associated StatelessConnect, from the connectionless StatelessConnect that negotiated the handshake. |
 |
void | Used to reset cached handshake success/fail state, when done processing it | |
 |
void | SetDriver
(
UNetDriver* InDriver |
Sets the net driver this handler is associated with |
 |
void | SetHandshakeFailureCallback
(
FHandshakeFailureFunc&& InHandshakeFailureFunc |
Set a callback for notifying of handshake failure (clientside only). |
Overridden from HandlerComponent
| Type | Name | Description | |
|---|---|---|---|
   |
bool | Whether or not the Incoming/IncomingConnectionless implementations, support reading Packets that aren't aligned at bit position 0 (i.e. whether or not this handler supports bit-level, rather than byte-level, reads) | |
   |
void | CountBytes
(
FArchive& Ar |
|
   |
int32 | Returns the amount of reserved packet/protocol bits expected from this component. | |
  |
void | IncomingConnectionless
(
FIncomingPacketRef PacketRef |
Handles incoming packets not associated with a UNetConnection |
  |
void | Initialize () |
Initialization functionality should be placed here |
   |
bool | IsValid () |
Return whether this handler is valid |
  |
void | Notification to this component that it is ready to begin handshaking | |
  |
void | Outgoing
(
FBitWriter& Packet, |
Handles any outgoing packets |
  |
void | Tick
(
float DeltaTime |
Tick functionality should be placed here |
