Detailed Description

An implementation of a single In-Band Bytestream (XEP-0047).

One instance of this class handles a single byte stream.

See SIProfileFT for a detailed description on how to implement file transfer.

Note: This class can receive data wrapped in Message stanzas. This will only work if you are not using MessageSessions. However, it will always send data using IQ stanzas (which will always work).

Constructor & Destructor Documentation

~InBandBytestream ( )

virtual

Virtual destructor.

Definition at line 114 of file inbandbytestream.cpp.

Member Function Documentation

int blockSize ( ) const

inline

Lets you retrieve this bytestream's block-size.

Returns: The bytestream's block-size.

Definition at line 58 of file inbandbytestream.h.

void close ( )

virtual

Closes the bytestream.

Implements Bytestream.

Definition at line 281 of file inbandbytestream.cpp.

bool connect ( )

virtual

This function starts the connection process.

Returns: True if a connection to a remote entity could be established, false otherwise.

Note: If false is returned you should pass this Bytestream object to SIProfileFT::dispose() for deletion.; Make sure you have a BytestreamDataHandler registered (using registerBytestreamDataHandler()) before calling this function.

Implements Bytestream.

Definition at line 127 of file inbandbytestream.cpp.

bool handleIq ( const IQ & iq )

virtual

Reimplement this function if you want to be notified about incoming IQs.

Parameters

iq	The complete IQ stanza.

Returns: Indicates whether a request of type 'get' or 'set' has been handled. This includes the obligatory 'result' answer. If you return false, a 'error' will be sent.

Since: 1.0

Implements IqHandler.

Definition at line 161 of file inbandbytestream.cpp.

void handleIqID	(	const IQ &	iq,
		int	context
	)

virtual

Reimplement this function if you want to be notified about incoming IQs with a specific value of the id attribute. You have to enable tracking of those IDs using Client::trackID(). This is usually useful for IDs that generate a positive reply, i.e. <iq type='result' id='reg'/> where a namespace filter wouldn't work.

Parameters

iq	The complete IQ stanza.
context	A value to restore context, stored with ClientBase::trackID().

Note: Only IQ stanzas of type 'result' or 'error' can arrive here.

Since: 1.0

Implements IqHandler.

Definition at line 142 of file inbandbytestream.cpp.

void handleMessage	(	const Message &	msg,
		MessageSession *	session = `0`
	)

virtual

Reimplement this function if you want to be notified about incoming messages.

Parameters

msg	The complete Message.
session	If this MessageHandler is used with a MessageSession, this parameter holds a pointer to that MessageSession.

Since: 1.0

Implements MessageHandler.

Definition at line 206 of file inbandbytestream.cpp.

virtual ConnectionError recv ( int timeout = -1 )

inlinevirtual

Call this function repeatedly to receive data. You should even do this if you use the bytestream to merely send data. May be a NOOP, depending on the actual stream type.

Parameters

timeout The timeout to use for select in microseconds. Default of -1 means blocking.

Returns: The state of the connection.

Implements Bytestream.

Definition at line 68 of file inbandbytestream.h.

bool send ( const std::string & data )

virtual

Use this function to send a chunk of data over an open bytestream. If the stream is not open or has been closed again (by the remote entity or locally), nothing is sent and false is returned. This function does any base64 encoding for you, if necessary.

Parameters

data	The block of data to send.

Returns: True if the data has been sent (no guarantee of receipt), false in case of an error.

Implements Bytestream.

Definition at line 247 of file inbandbytestream.cpp.

void setBlockSize ( int blockSize )

inline

Sets the stream's block-size. Default: 4096

Parameters

blockSize The new block size.

Note: You should not change the block size once connect() has been called.

Definition at line 65 of file inbandbytestream.h.
