Detailed Description

A port that is specialized as an RPC server.

That is, it expects to receive connections from multiple clients, and to reply to them via those connections.

Member Function Documentation

◆ asPort() [1/2]

const Port & yarp::os::RpcServer::asPort ( ) const
inlineoverridevirtual

Get the concrete Port being used for communication, const version.

Implements yarp::os::AbstractContactable.

Definition at line 60 of file RpcServer.h.

◆ asPort() [2/2]

Port & yarp::os::RpcServer::asPort ( )
inlineoverridevirtual

Get the concrete Port being used for communication.

Implements yarp::os::AbstractContactable.

Definition at line 55 of file RpcServer.h.

◆ read()

bool RpcServer::read ( PortReader reader,
bool  willReply = true 
)
overridevirtual

Read an object from the port.

Parameters
readerany object that knows how to read itself from a network connection - see for example Bottle
willReplyyou must set this to true if you intend to call reply()
Returns
true iff the object is successfully read

Reimplemented from yarp::os::AbstractContactable.

Definition at line 49 of file RpcServer.cpp.

◆ setInputMode()

void RpcServer::setInputMode ( bool  expectInput)
overridevirtual

Configure the port to allow or forbid inputs.

By default, ports allow anything.

Parameters
expectInputset to true if this port will be used for input

Reimplemented from yarp::os::AbstractContactable.

Definition at line 59 of file RpcServer.cpp.

◆ setOutputMode()

void RpcServer::setOutputMode ( bool  expectOutput)
overridevirtual

Configure the port to allow or forbid outputs.

By default, ports allow anything.

Parameters
expectOutputset to true if this port will be used for output

Reimplemented from yarp::os::AbstractContactable.

Definition at line 65 of file RpcServer.cpp.

◆ setRpcMode()

void RpcServer::setRpcMode ( bool  expectRpc)
overridevirtual

Configure the port to be RPC only.

By default all ports can be used for RPC or streaming communication.

Parameters
expectRpcset to true if this port will be used for RPC only

Reimplemented from yarp::os::AbstractContactable.

Definition at line 71 of file RpcServer.cpp.

◆ write() [1/2]

bool RpcServer::write ( const PortWriter writer,
const PortWriter callback = nullptr 
) const
overridevirtual

Write cannot be called by RPCServer.

Reimplemented from yarp::os::AbstractContactable.

Definition at line 30 of file RpcServer.cpp.

◆ write() [2/2]

bool RpcServer::write ( const PortWriter writer,
PortReader reader,
const PortWriter callback = nullptr 
) const
overridevirtual

Write cannot be called by RPCServer.
