LangGraphでは、条件に応じてノード間の遷移を制御できます。この遷移を決定するのが
条件チェック関数です。状態遷移の条件チェック関数も、ノード関数と同様に状態を引数とし
ます。条件チェック関数の戻り値は、次の状態を決定します。
次に
check_goal
関数の定義を示します。
def check_goal(state: PiggyBankState, goal: int) -> dict:
if state["total"] >= goal:
return "full"
else:
return "continue"
ここでは、
total
が目標金額以上であれば
"full"
を返し、それ以外の場合は
"continue"
を
返します。目標金額である
goal
は、この関数の引数として受け取ります。ただし、
LangGraphでは条件チェック関数は状態のみを引数とする必要があります。このため、後の
