策略模式的意图是定义一系列算法,把它们一个一个封装起来,并且使它们可以互相替换。通常每个策略算法不可抽象再分。本人仿照https://www.runoob.com/design-pattern/strategy-pattern.html所给的例子,用Matlab代码对其进行实现 Strategy.m ......
策略模式的意图是定义一系列算法,把它们一个一个封装起来,并且使它们可以互相替换。通常每个策略算法不可抽象再分。本人仿照所给的例子,用matlab代码对其进行实现
strategy.m
classdef strategy < handle
methods(abstract)
dooperation(~,~,~);
end
end
operationadd.m
classdef operationadd < strategy
methods
function res = dooperation(~,num1,num2)
res = num1 + num2;
end
end
end
operationmultiply.m
classdef operationmultiply < strategy
methods
function res = dooperation(~,num1,num2)
res = num1 * num2;
end
end
end
context.m
classdef context < handle
properties
strategy
end
methods
function obj = context(strategy)
obj.strategy = strategy;
end
function res = executestrategy(obj,num1,num2)
res = obj.strategy.dooperation(num1,num2);
end
end
end
测试代码:
context = context(operationadd());
disp("2 + 3 = " + context.executestrategy(2, 3));
context =context(operationmultiply());
disp("2 * 3 = " + context.executestrategy(2, 3));
