on_tick()

HookId MayaFlux::Nodes::ChainNode::on_tick ( const NodeHook &  callback )

inlineoverridevirtual

Registers a callback to be called on each tick.

Parameters

callback

Function to call with the current node context

Registers a callback function that will be called each time the node produces a new output value. The callback receives a NodeContext object containing information about the node's current state.

This mechanism enables external components to monitor and react to the node's activity without interrupting the processing flow.

Example:

node->on_tick([](NodeContext& ctx) {
    std::cout << "Node produced value: " << ctx.value << std::endl;
});

Returns

Id of the registration, usable with unhook(). A callback equivalent to one already registered is not added again and the existing id is returned.

Reimplemented from MayaFlux::Nodes::Node.
