Detailed Description

SocketConnection - an interface for creating a socket connection using AzSocket

Member Typedef Documentation

TMessageCallback

typedef AZStd::function<void(AZ::u32, AZ::u32, const void*, AZ::u32)> AzFramework::SocketConnection::TMessageCallback

Callback parameters: Message ID, Serial, Data Buffer, Data Length Note that if the message is a request and it failed because of a protocol error (engine is shutting down for example) It is still guaranteed to be called, but will be called with 0, nullptr

Member Function Documentation

AddMessageHandler()

virtual TMessageCallbackHandle AzFramework::SocketConnection::AddMessageHandler ( AZ::u32  typeId, TMessageCallback  callback  )

pure virtual

Add callback for specific typeId (allows multiple callbacks per id) This will be invoked when a complete message is received from the remote end

Implemented in AzFramework::AssetSystem::AssetProcessorConnection.

Connect()

virtual bool AzFramework::SocketConnection::Connect ( const char *  address, AZ::u16  port  )

pure virtual

Connect to an address with this connection. Takes a null-terminated string address and a port Currently this blocks until connected

Implemented in AzFramework::AssetSystem::AssetProcessorConnection.

Disconnect()

virtual bool AzFramework::SocketConnection::Disconnect ( bool  completeDisconnect = false )

pure virtual

Disconnect from connection - Only works if actually connected completeDisconnect - True if this function should wait for the connection to be fully terminated before returning. False for async behavior.

Implemented in AzFramework::AssetSystem::AssetProcessorConnection.

Listen()

virtual bool AzFramework::SocketConnection::Listen ( AZ::u16  port )

pure virtual

Listen for one connection on a port This does not block and will set state to listening until connected

Implemented in AzFramework::AssetSystem::AssetProcessorConnection.
