get_metadata()

std::unordered_map< std::string, std::string > MayaFlux::Nodes::Network::ParticleNetwork::get_metadata ( ) const

overridevirtual

Get network metadata for debugging/visualization.

Returns

Map of property names to string representations

Subclasses can override to expose internal state:

• Particle count, average velocity
• Modal frequencies, decay times
• Waveguide delay lengths etc.

Reimplemented from MayaFlux::Nodes::Network::NodeNetwork.
