golang 设计模式 chain_test 代码实现

package chain

func ExampleChain() {
	c1 := NewProjectManagerChain()
	c2 := NewDepManagerChain()
	c3 := NewGeneralManagerChain()

	c1.SetSuccessor(c2)
	c2.SetSuccessor(c3)

	var c Manager = c1

	c.HandleFeeRequest("bob", 400)
	c.HandleFeeRequest("tom", 1400)
	c.HandleFeeRequest("ada", 10000)
	c.HandleFeeRequest("floar", 400)
	// Output:
	// Project manager permit bob 400 fee request
	// Dep manager permit tom 1400 fee request
	// General manager permit ada 10000 fee request
	// Project manager don't permit floar 400 fee request
