ahead()

template<typename Handle >

const VisionStep * MayaFlux::Kinesis::Vision::VisionPass< Handle >::ahead ( size_t  offset = 1 ) const

inlinenoexcept

Op at offset steps ahead, or nullptr past the end.

Replaces the adjacency booleans derived by VisionSequence::Builder. Correct under any mutation of steps because it is evaluated at the point of use.
