Member Function Documentation

void ns3::UdpEchoClient::DoDispose ( void )

protectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Application.

Definition at line 122 of file udp-echo-client.cc.

References ns3::Application::DoDispose(), and NS_LOG_FUNCTION.

Here is the call graph for this function:

uint32_t ns3::UdpEchoClient::GetDataSize ( void ) const

Get the number of data bytes that will be sent to the server.

Warning: The number of bytes may be modified by calling any one of the SetFill methods. If you have called SetFill, then the number of data bytes will correspond to the size of an initialized data buffer. If you have not called a SetFill method, the number of data bytes will correspond to the number of don't care bytes that will be sent.

Returns: The number of data bytes.

void ns3::UdpEchoClient::SetDataSize ( uint32_t dataSize )

Set the data size of the packet (the number of bytes that are sent as data to the server).

The contents of the data are set to unspecified (don't care) by this call.

Warning: If you have set the fill data for the echo client using one of the SetFill calls, this will undo those effects.

Parameters

dataSize The size of the echo data you want to sent.

void ns3::UdpEchoClient::SetFill ( std::string fill )

Set the data fill of the packet (what is sent as data to the server) to the zero-terminated contents of the fill string string.

Warning: The size of resulting echo packets will be automatically adjusted to reflect the size of the fill string – this means that the PacketSize attribute may be changed as a result of this call.

Parameters

fill	The string to use as the actual echo data bytes.

Definition at line 193 of file udp-echo-client.cc.

References m_data, m_dataSize, m_size, and NS_LOG_FUNCTION.

void ns3::UdpEchoClient::SetFill	(	uint8_t	fill,
		uint32_t	dataSize
	)

Set the data fill of the packet (what is sent as data to the server) to the repeated contents of the fill byte.

i.e., the fill byte will be used to initialize the contents of the data packet.

Warning: The size of resulting echo packets will be automatically adjusted to reflect the dataSize parameter – this means that the PacketSize attribute may be changed as a result of this call.

Parameters

fill	The byte to be repeated in constructing the packet data..
dataSize	The desired size of the resulting echo packet data.

Definition at line 215 of file udp-echo-client.cc.

References m_data, m_dataSize, m_size, and NS_LOG_FUNCTION.

void ns3::UdpEchoClient::SetFill	(	uint8_t *	fill,
		uint32_t	fillSize,
		uint32_t	dataSize
	)

Set the data fill of the packet (what is sent as data to the server) to the contents of the fill buffer, repeated as many times as is required.

Initializing the packet to the contents of a provided single buffer is accomplished by setting the fillSize set to your desired dataSize (and providing an appropriate buffer).

Warning: The size of resulting echo packets will be automatically adjusted to reflect the dataSize parameter – this means that the PacketSize attribute of the Application may be changed as a result of this call.

Parameters

fill	The fill pattern to use when constructing packets.
fillSize	The number of bytes in the provided fill pattern.
dataSize	The desired size of the final echo data.
