示例1: assign
void assign(state_type state, tree_type& tree)
{
features_ += *state.feature_vector();
switch (state.operation().operation()) {
case operation_type::AXIOM:
break;
case operation_type::FINAL:
case operation_type::IDLE:
assign(state.derivation(), tree);
break;
case operation_type::UNARY:
tree.label_ = state.label();
tree.antecedent_.resize(1);
assign(state.derivation(), tree.antecedent_.front());
break;
case operation_type::SHIFT:
tree.label_ = state.label();
tree.antecedent_ = tree_type::antecedent_type(1, state.head());
break;
case operation_type::REDUCE:
case operation_type::REDUCE_LEFT:
