operator>>() [1/2]

MAYAFLUX_API std::shared_ptr< Nodes::Node > MayaFlux::operator>>	(	const std::shared_ptr< Nodes::Node > &	lhs,
		const std::shared_ptr< Nodes::Node > &	rhs
	)

Connects two nodes in series (pipeline operator)

Parameters

lhs	Source node (may already be a ChainNode)
rhs	Target node (may already be a ChainNode)

Returns

A ChainNode containing the flattened sequence

If lhs is already a ChainNode, rhs is appended to its sequence rather than creating a nested chain.

Uses the default engine's NodeGraphManager for registration. For manual construction without registration, create ChainNode directly with no manager argument.

auto chain = generator >> transformer >> output;
