	NetworkManager (const NetworkManager &obj)=delete
	Deleted the copy constructor for singleton.
OpId	addOperator (op::OpInfo opInfo)
	Creates a new node in the network.
std::optional< OpId >	getDisplayOp ()
	Returns the operator ID for the node with its display flag set. There can only be only be one operator displayed at a time. Return value is nullopt if no node is set to display.
bool	isValidOp (nt::OpId opId)
	Returns whether the node exists in the network and is valid.
GeometryOperator &	getGeoOperator (nt::OpId opId)
	Returns a reference to the GeometryOperator with the given OpId.
void	setDisplayOp (OpId opId)
	Sets given OpId to be displayed, releasing previous display Node.
void	setSelectedNode (OpId opId, bool selected, bool add=false)
	Set the selection state for the given node.

Detailed Description

The central coordinator of the engine's node system.

The network manager is the central coordinator of the engine’s node system. It manages the lifecycle of operators, including their creation, storage, and validation, while also tracking dependencies between them. Acting as a singleton, it ensures that all parts of the engine work with a single consistent view of the network, providing global access. Beyond just storing operators, it also controls cooking and traversing dependency graphs, ensuring that updates flow correctly through the network when nodes change.

Todo

remove Qobject inheritance, this is no longer needed since switching to boost signals.

Member Function Documentation

addOperator()

enzo::nt::OpId enzo::nt::NetworkManager::addOperator

(

op::OpInfo

opInfo

)

Creates a new node in the network.

Parameters

OpInfo

Data designating the properties of the node.

Returns

The operator ID of the newly created node

isValidOp()

bool enzo::nt::NetworkManager::isValidOp

(

nt::OpId

opId

)

Returns whether the node exists in the network and is valid.

Parameters

opId	Operator ID of the node to check the validity of.

setSelectedNode()

void enzo::nt::NetworkManager::setSelectedNode	(	OpId	opId,
		bool	selected,
		bool	add = false )

Set the selection state for the given node.

Parameters

opId	The node to set the state on.
selected	The selection state, true selects the node, false unselects it.
add	By default all other nodes are unselected, this parameter allows adding a selected node without deslecting any others.
