請問這是用java語言寫的程式碼嗎？
class hello : public eosio::contract {
public:
using contract::contract;
/// @abi action
void hi( account_name from, account_name to) {
require_auth(from);
print( “Hello, from:”, name{from}, “, to:”, name{to});
action(
//這裡{to, active}必須授權給{_self, eosio.code}
permission_level{to, N(active)},
//呼叫 hello.target合約 的’callme’ action
N(hello.target), N(callme),
std::make_tuple(to)
).send();
}
};
