static vtkTypeBool vtkSocket::IsTypeOf ( const char * type )

static

virtual vtkTypeBool vtkSocket::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Reimplemented in vtkServerSocket, and vtkClientSocket.

static vtkSocket* vtkSocket::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkSocket::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented in vtkServerSocket, and vtkClientSocket.

vtkSocket* vtkSocket::NewInstance ( ) const

void vtkSocket::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

int vtkSocket::GetConnected ( )

inline

Check is the socket is alive.

Definition at line 40 of file vtkSocket.h.

void vtkSocket::CloseSocket ( )

Close the socket.

int vtkSocket::Send	(	const void *	data,
		int	length
	)

These methods send data over the socket.

Returns 1 on success, 0 on error and raises vtkCommand::ErrorEvent.

int vtkSocket::Receive	(	void *	data,
		int	length,
		int	readFully = `1`
	)

Receive data from the socket.

This call blocks until some data is read from the socket. When readFully is set, this call will block until all the requested data is read from the socket. 0 on error, else number of bytes read is returned. On error, vtkCommand::ErrorEvent is raised.

virtual int vtkSocket::GetSocketDescriptor ( )

virtual

Provides access to the internal socket descriptor.

This is valid only when GetConnected() returns true.

static int vtkSocket::SelectSockets	(	const int *	sockets_to_select,
		int	size,
		unsigned long	msec,
		int *	selected_index
	)

static

Selects set of sockets.

Returns 0 on timeout, -1 on error. 1 on success. Selected socket's index is returned through selected_index

int vtkSocket::CreateSocket ( )

protected

Creates an endpoint for communication and returns the descriptor.

-1 indicates error.

void vtkSocket::CloseSocket ( int socketdescriptor )

protected

Close the socket.

int vtkSocket::BindSocket	(	int	socketdescriptor,
		int	port
	)

protected

Binds socket to a particular port.

Returns 0 on success other -1 is returned.

int vtkSocket::SelectSocket	(	int	socketdescriptor,
		unsigned long	msec
	)

protected

Selects a socket ie.

waits for it to change status. Returns 1 on success; 0 on timeout; -1 on error. msec=0 implies no timeout.

int vtkSocket::Accept ( int socketdescriptor )

protected

Accept a connection on a socket.

Returns -1 on error. Otherwise the descriptor of the accepted socket.

int vtkSocket::Listen ( int socketdescriptor )

protected

Listen for connections on a socket.

Returns 0 on success. -1 on error.

int vtkSocket::Connect	(	int	socketdescriptor,
		const char *	hostname,
		int	port
	)

protected

Connect to a server socket.

Returns 0 on success, -1 on error.

int vtkSocket::GetPort ( int socketdescriptor )

protected

Returns the port to which the socket is connected.

0 on error.
