request_reset_from_channel()

void MayaFlux::Nodes::Node::request_reset_from_channel

(

uint32_t

channel_id

)

Requests a reset of the processed state from a specific channel.

Parameters

channel_id

The ID of the channel requesting the reset

This method is called by channels to signal that they have completed their processing and that the node's processed state should be reset. It uses a bitmask to track pending resets and ensures that all channels have completed before actually resetting the node's state.
