Detailed Description

ZeroMQ client for Rogue control and update messaging.

ZmqClient connects to a ZmqServer endpoint and supports two operating modes selected by doString:

Binary mode (doString == false): subscribes to update messages and uses request/reply for binary RPC payloads.
String mode (doString == true): uses a string request/reply endpoint for high-level display/value operations.

In binary mode, a background thread receives publish updates and dispatches them to doUpdate().

Constructor & Destructor Documentation

◆ ZmqClient()

rogue::interfaces::ZmqClient::ZmqClient	(	const std::string &	addr,
		uint16_t	port,
		bool	doString
	)

Constructs a ZeroMQ client and connects sockets.

This constructor is a low-level C++ allocation path. Prefer create() when shared ownership or Python exposure is required.

Parameters

addr	Server bind address or host.
port	Base server port.
doString	`true` for string request mode, `false` for binary mode.

Definition at line 94 of file ZmqClient.cpp.

◆ ~ZmqClient()

rogue::interfaces::ZmqClient::~ZmqClient ( )

virtual

Destroys client and stops background activity.

Definition at line 175 of file ZmqClient.cpp.

Member Function Documentation

◆ create()

rogue::interfaces::ZmqClientPtr rogue::interfaces::ZmqClient::create	(	const std::string &	addr,
		uint16_t	port,
		bool	doString
	)

static

Creates a ZeroMQ client.

Parameter semantics are identical to the constructor; see ZmqClient() for socket setup behavior details. This static factory is the preferred construction path when the object is shared across Rogue graph connections or exposed to Python. It returns std::shared_ptr ownership compatible with Rogue pointer typedefs.

Parameters

addr	Server bind address or host.
port	Base server port.
doString	`true` for string request mode, `false` for binary mode.

Returns: Shared pointer to the created client.

Definition at line 71 of file ZmqClient.cpp.

◆ doUpdate()

void rogue::interfaces::ZmqClient::doUpdate ( boost::python::object data )

virtual

Handles async update payloads received on subscriber socket.

Parameters

data	Update payload as Python object.

Reimplemented in rogue::interfaces::ZmqClientWrap.

Definition at line 319 of file ZmqClient.cpp.

◆ exec()

std::string rogue::interfaces::ZmqClient::exec	(	const std::string &	path,
		const std::string &	arg = `""`
	)

Executes callable node at path (string mode).

Parameters

path	Rogue node path.
arg	Optional argument string.

Returns: Callable result as string.

Definition at line 256 of file ZmqClient.cpp.

◆ getDisp()

std::string rogue::interfaces::ZmqClient::getDisp ( const std::string & path )

Reads display-formatted value at a path (string mode).

Parameters

path	Rogue node path.

Returns: Display-formatted value.

Definition at line 248 of file ZmqClient.cpp.

◆ send()

boost::python::object rogue::interfaces::ZmqClient::send ( boost::python::object data )

Sends binary request payload and receives binary response.

Parameters

data	Python object exposing a readable buffer.

Returns: Response bytes as a Python bytes-like object.

Definition at line 266 of file ZmqClient.cpp.

◆ sendString()

std::string rogue::interfaces::ZmqClient::sendString	(	const std::string &	path,
		const std::string &	attr,
		const std::string &	arg
	)

Sends a string-mode request.

Parameters

path	Rogue node path.
attr	Attribute or operation name.
arg	Optional argument string.

Returns: Server response string.

Definition at line 204 of file ZmqClient.cpp.

◆ setDisp()

void rogue::interfaces::ZmqClient::setDisp	(	const std::string &	path,
		const std::string &	value
	)

Writes display-formatted value at a path (string mode).

Parameters

path	Rogue node path.
value	Value string to apply.

Definition at line 252 of file ZmqClient.cpp.

◆ setTimeout()

void rogue::interfaces::ZmqClient::setTimeout	(	uint32_t	msecs,
		bool	waitRetry
	)

Sets request timeout behavior.

Parameters

msecs	Timeout in milliseconds.
waitRetry	`true` to continue waiting/retrying after timeouts.

Definition at line 194 of file ZmqClient.cpp.

◆ setup_python()

void rogue::interfaces::ZmqClient::setup_python ( )

static

Registers Python bindings for this class.

Setup class in python.

Definition at line 77 of file ZmqClient.cpp.

◆ stop()

void rogue::interfaces::ZmqClient::stop ( )

Stops client sockets and background thread.

Definition at line 179 of file ZmqClient.cpp.

◆ valueDisp()

std::string rogue::interfaces::ZmqClient::valueDisp ( const std::string & path )

Reads compact value display at a path (string mode).

Parameters

path	Rogue node path.

Returns: Value display string.
