int writeString(const String &data, uint8_t apiflags = TCP_WRITE_FLAG_COPY)

virtual int write(const char *data, int len, uint8_t apiflags = TCP_WRITE_FLAG_COPY)

Base write operation.

Parameters

• data:
• len:
• apiflags: TCP_WRITE_FLAG_COPY, TCP_WRITE_FLAG_MORE

Return Value

• int: -1 on error

int write(IDataSourceStream *stream)

uint16_t getAvailableWriteSize()

void flush()

void setTimeOut(uint16_t waitTimeOut)

IpAddress getRemoteIp() const

uint16_t getRemotePort() const

void setDestroyedDelegate(TcpConnectionDestroyedDelegate destroyedDelegate)

Sets a callback to be called when the object instance is destroyed.

Parameters

• destroyedDelegate:

void setSslInitHandler(Ssl::Session::InitDelegate handler)

Set the SSL session initialisation callback.

Parameters

• handler:

bool setSslConnection(Ssl::Connection *connection)

Ssl::Session *getSsl()

Get a pointer to the current SSL session object.

Note that this is typically used so we can query properties of an established session. If you need to change session parameters this must be done via setSslInitHandler.
