Constructor & Destructor Documentation

SIGTransport

(

const char *

name = 0

)

[inline, protected]

Constructor

Parameters:

name	Default empty component name

---

Member Function Documentation

void attach

(

SIGTRAN *

sigtran

)

[protected]

Attach an user adaptation layer

Parameters:

sigtran

SIGTRAN component to attach, can be NULL

virtual void attached

(

bool

hasUAL

)

[protected, pure virtual]

Notification if the attached state changed

Parameters:

hasUAL

True if an User Adaptation Layer is now attached

virtual bool connected

(

int

streamId

)

const [pure virtual]

Check if the network transport layer is connected

Parameters:

streamId

Identifier of the stream to check if applicable

Returns:

True if the transport (and stream if applicable) is connected

bool processMSG	(	unsigned char	msgVersion,
		unsigned char	msgClass,
		unsigned char	msgType,
		const DataBlock &	msg,
		int	streamId
	)		const [protected]

Send a complete message to the adaptation layer for processing

Parameters:

msgVersion	Version of the protocol
msgClass	Class of the message
msgType	Type of the message, depends on the class
msg	Message data, may be empty
streamId	Identifier of the stream the message was received on

Returns:

True if the message was handled

SIGTRAN* sigtran

(

)

const [inline]

Get the SIGTRAN component attached to this transport

Returns:

Pointer to adaptation layer or NULL

virtual bool transmitMSG	(	unsigned char	msgVersion,
		unsigned char	msgClass,
		unsigned char	msgType,
		const DataBlock &	msg,
		int	streamId = 0
	)		[protected, virtual]

Transmit a message to the network

Parameters:

msgVersion	Version of the protocol
msgClass	Class of the message
msgType	Type of the message, depends on the class
msg	Message data, may be empty
streamId	Identifier of the stream to send the data over

Returns:

True if the message was transmitted to network

virtual bool transmitMSG	(	const DataBlock &	header,
		const DataBlock &	msg,
		int	streamId = 0
	)		[protected, pure virtual]

Transmit a prepared message to the network

Parameters:

header	Message header, typically 8 octets
msg	Message data, may be empty
streamId	Identifier of the stream to send the data over

Returns:

True if the message was transmitted to network
