json_to_world()

void serial::json_to_world	(	const nlohmann::json &	j,
		core::World &	world,
		std::mt19937 &	masterSeeder
	)

Deserializes a nlohmann::json object and reconstructs the simulation world.

This function is the counterpart to world_to_json. It performs a full state replacement by clearing the existing world and rebuilding it from the provided JSON. This "replace" strategy simplifies state management, guaranteeing that the C++ core is always perfectly synchronized with the state provided by the UI without requiring complex diffing or patching logic. It also handles re-seeding the master random number generator to ensure that loading a state also restores its deterministic behavior.

Parameters

j	The json object to deserialize.
world	The world object to populate.
masterSeeder	A reference to the master random number generator, which will be re-seeded.

parseSimulation()

void serial::parseSimulation	(	const std::string &	filename,
		core::World *	world,
		bool	validate,
		std::mt19937 &	masterSeeder
	)

Parses a simulation configuration from an XML file.

This function acts as the primary facade for the simulator's XML loading pipeline. It performs the following steps:

1. Resets the target World and global parameters (params::params).
2. Loads the main XML file.
3. Recursively finds and merges any <include> files into the main document.
4. Optionally validates the combined document against the built-in DTD and XSD schemas.
5. Uses the internal parser utilities to instantiate simulation objects.
6. Updates the global params::params with the parsed context parameters.

Parameters

filename	The filesystem path to the main XML simulation script.
world	A pointer to the World object to be populated with parsed components.
validate	A boolean indicating whether to perform strict XML schema validation.
masterSeeder	A reference to the master random number generator used for assigning independent seeds to components.

Exceptions

XmlException	if the XML is malformed, fails schema validation, or contains invalid scenario logic.
std::runtime_error	for file I/O errors or other critical setup issues.

parseSimulationFromString()

void serial::parseSimulationFromString	(	const std::string &	xmlContent,
		core::World *	world,
		bool	validate,
		std::mt19937 &	masterSeeder
	)

Parses a simulation configuration directly from an XML string in memory.

Similar to parseSimulation, but operates on a raw string instead of a file. Because it does not load from the filesystem, <include> tags are ignored, and any relative paths for file-backed assets (like waveforms or antennas) will be resolved against the current working directory (.).

Parameters

xmlContent	The raw XML string containing the scenario definition.
world	A pointer to the World object to be populated with parsed components.
validate	A boolean indicating whether to perform strict XML schema validation.
masterSeeder	A reference to the master random number generator used for assigning independent seeds to components.

Exceptions

XmlException

if the XML string is malformed, fails schema validation, or contains invalid scenario logic.

readPattern()

std::vector< std::vector< RealType > > serial::readPattern	(	const std::string &	name,
		const std::string &	datasetName
	)

Reads a 2D antenna gain pattern from the named dataset.

Reads a 2D pattern dataset from an HDF5 file.

Parameters

name	The name of the HDF5 file.
datasetName	The name of the dataset to be read.

Returns

A 2D vector containing the pattern data.

Exceptions

std::runtime_error

If there is an error handling the file or if the dataset dimensions are invalid.

world_to_json()

nlohmann::json serial::world_to_json

(

const core::World &

world

)

Serializes the entire simulation world into a nlohmann::json object.

This function traverses the core::World object model and constructs a JSON representation. It is designed to produce a format that is convenient for the frontend to consume. This involves translating internal data formats (e.g., angles in radians) to a more UI-friendly format (e.g., compass degrees) and restructuring complex object relationships (like monostatic radars) into simpler representations.

Parameters

world

The world object to serialize.

Returns

A nlohmann::json object representing the world.

world_to_xml_string()

std::string serial::world_to_xml_string

(

const core::World &

world

)

Serializes the entire simulation world into an XML formatted string.

This function serves as the reverse of the XML parser. It is essential for allowing users to modify a scenario in a UI and then export their changes back into a valid FERS XML file that can be used by the CLI or shared. It iterates through the in-memory core::World object and reconstructs the corresponding XML structure.

Parameters

world

The world object to serialize.

Returns

A string containing the XML representation of the world.
