SelfAwarePlainBranch< U, Args >

Description

template<typename U, typename... Args>
class Darwin::Tools::SelfAwarePlainBranch< U, Args >

Type for a plain-type branch that knows how to fill itself.

Given a DT::Flow flow object:

auto filler = [](int i) -> int { return i*2;};
SelfAwarePlainBranch<int> br(flow, "branch", filler);
br.Fill(42);

is effectively equivalent to

auto br = flow.SetBranchWriteOnly<int>("branch");
*br = filler(42);
