我正在開發一個VHDL狀態機,它似乎沒有正常工作。設計如下所示: SHARED VARIABLE XM_INDEX : NATURAL RANGE 0 TO 99 := 0;
SIGNAL XM_STATE_INDICATOR : STD_LOGIC_VECTOR (7 DOWNTO 0) := "00000000";
TYPE XM_STATE_TYPE IS (EMPTY, IDLE, P
假設我有這個類: case class Receipt(id: Long, state: String) {
def transitionTo(newState: String) = {
if (!canTransitionTo(newState)) {
throw new IllegalStateExcetion(s"cant transition from $s
我試圖在兩種模式使用一個狀態機,並讓他們的模塊 module Schedulable
state_machine :state, initial: :unscheduled
end
class Install < ActiveRecord::Base
include Schedulable
end
在分享它,我收到以下錯誤 NameError: undefined local va
我在單獨的線程中有20個併發用戶處理命令。我如何使用彈簧狀態機來維持狀態? 我想: public class myclass extends EnumStateMachineConfigurerAdapter<OrderState, OrderEvents>
@Override
public void configure(StateMachineTransitionConfigure
