Member Function Documentation

◆ dump()

void PPTServer::dump ( std::ostream &  strm) const
virtual

dumps information about this object

Displays the pointer value of this instance

Parameters
strmC++ i/o stream to dump the information to

Reimplemented from PPTConnection.

Definition at line 274 of file PPTServer.cc.

◆ initConnection()

void PPTServer::initConnection ( )
virtual

Using the info passed into the SocketLister, wait for an inbound request (see SocketListener::accept()). When one is found, do the welcome message stuff (welcomeClient()) and then pass this to the handler's handle method. Note that this is a pointer to a PPTServer which is a kind of Connection.

Implements PPTConnection.

Definition at line 136 of file PPTServer.cc.

◆ read_extensions()

void PPTConnection::read_extensions ( std::map< std::string, std::string > &  extensions,
const std::string &  xstr 
)
protectedvirtualinherited

the string passed are extensions, read them and store the name/value pairs into the passed map

It has already been determined that extensions were read in the chunk. Deconstruct the name/value pairs and store them into the map passed. Each extension ends with a semicolon.

Parameters
extensionsmap to store the name/value pairs in
xstrstring of extensions in the form *(name[=value];)

Definition at line 370 of file PPTConnection.cc.

◆ readBuffer()

int PPTConnection::readBuffer ( char *  buffer,
const unsigned int  buffer_size 
)
protectedvirtualinherited

read a buffer of data from the socket

Parameters
bufferbuffer to store the data received from the socket in
buffer_sizemax size of the data to be received
Returns
number of bytes actually read

Definition at line 204 of file PPTConnection.cc.

◆ readBufferNonBlocking()

int PPTConnection::readBufferNonBlocking ( char *  inBuff,
const int  buffer_size 
)
protectedvirtualinherited

read a buffer of data from the socket without blocking

Try to read a buffer of data without blocking. We will try _timeout times, waiting 1000 milliseconds between each try. The variable _timeout is passed into the constructor.

Parameters
inBuffbuffer to store the data into
buffer_sizethe size of the passed buffer
Returns
number of bytes read in, -1 if failed to read anything

Definition at line 418 of file PPTConnection.cc.

◆ receive()

bool PPTConnection::receive ( std::map< std::string, std::string > &  extensions,
std::ostream *  strm = 0 
)
virtualinherited

receive a chunk of either extensions into the specified map or data into the specified stream

This receive will read a chunk of information from the socket and determine if what is read are extensions, where they are stored in the extensions map passed, or data, which is written to the specified stream

The first 7 bytes is the length of the information that was passed. The 5th character is either the character 'x', signifying that extensions were sent, or 'd', signifying that data was sent.

Parameters
extensionsmap to store the name/value paris into
strmoutput stream to write the received data into
Returns
true if what was received is the last chunk, false otherwise

Implements Connection.

Definition at line 253 of file PPTConnection.cc.

◆ send() [1/2]

void PPTConnection::send ( const std::string &  buffer)
protectedvirtualinherited

sends the buffer to the socket

the buffer includes the length, extensions, data, whatever is to be sent

Parameters
bufferdata buffer to send to the socket

Implements Connection.

Definition at line 184 of file PPTConnection.cc.

◆ send() [2/2]

void PPTConnection::send ( const std::string &  buffer,
std::map< std::string, std::string > &  extensions 
)
virtualinherited

Send a message to the server.

Sends the specified message buffer to the server followed by a buffer of length 0 to signify the end of the message

A buffer sent to the server will follow the following form:

Chunked-Body = chunk-extensions
chunk
last-chunk
chunk-extensions= chunk-size 'x' *( chunk-ext-name [ "=" chunk-ext-val ] ;
chunk = chunk-size 'd' chunk-data
chunk-size = 8HEX
last-chunk = 7("0") d
chunk-ext-name = token
chunk-ext-val = token | quoted-string
chunk-data = chunk-size(OCTET)

If there are extensions then they are sent first. The length of the extensions is sent first, followed by the character 'x', and then the extensions in the format name[=value];

Then the buffer itself is sent. The length of the buffer is sent followed by the character 'd' signifying data is being transmitted.

if the buffer is empty then this represents the last chunk

Parameters
bufferbuffer of data to send
extensionslist of name/value pairs sent

Implements Connection.

Definition at line 103 of file PPTConnection.cc.

◆ sendExit()

void PPTConnection::sendExit ( )
virtualinherited

Send the exit token as an extension.

Implements Connection.

Definition at line 119 of file PPTConnection.cc.

◆ sendExtensions()

void PPTConnection::sendExtensions ( std::map< std::string, std::string > &  extensions)
virtualinherited

send the specified extensions

Parameters
extensionsname/value paris to be sent

Implements Connection.

Definition at line 156 of file PPTConnection.cc.
