pull()

BuffHandle pull ( uint  portIdx, BuffHandle  output, Time  nomTime, ProcessKey  procKey  )

inline

Engine Core operation: render and pull output from this node.

Activate the indicated Port, which may recursively pull from »Lead Nodes« (predecessors) and invoke the operation embodied by this node. The stack frame of this call acts as anchor to hold the TurnoutSystem for parameter access and coordination.

Parameters

portIdx	the port (≙flavour) to activate
output	a BuffHandle configured suitably to hold results
nomTime	absolute nominal Time to key this invocation
procKey	additional process key for context parameters

Returns

handle to the buffer containing the calculated result.
