java - java中如何将函数传递给方法参数

Question

APIResponse res = kpiAPIObject.getALLKPIDefinition(); --> 函数a

boolean 状态 = res.getNodeValues("shortName").contains(kpiName); --> 函数b

public void dynamicWait(function a,function b)
{
    long t = System.currentTimeMillis();
    while (t > System.currentTimeMillis() - 180000 ) {
        res = /* execute function a here */
        if(/* execute function b here */) {
            break;
        } else {
            Thread.sleep(30000);
            continue;
        }
    }  
}

Answer 1

听起来你可以使用一些 lambda:

Supplier<APIResponse> a = kpiAPIObject::getALLKPIDefinition;
Predicate<APIResponse> b = res -> res.getNodeValues("shortName").contains(kpiName);

然后这样调用它们:

APIResponse res = a.get();
if (b.test(res)) {
    break;
}
