Dispatcher (bus-all 5.5.0 API)

java.lang.Object
- org.aoju.bus.http.metric.Dispatcher

```
public final class Dispatcher
extends Object
```
关于何时执行异步请求的策略每个dispatcher使用一个ExecutorService在内部运行调用。如果您提供自己的执行程序，它应该能够并发地运行配置的最大调用数

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`cancelAll()` 取消当前排队或执行的所有调用。包括同步执行的 NewCall.execute()和异步执行的NewCall.enqueue(org.aoju.bus.http.Callback)。
`void`	`enqueue(RealCall.AsyncCall call)`
`void`	`executed(RealCall call)`
`ExecutorService`	`executorService()`
`void`	`finished(RealCall.AsyncCall call)`
`void`	`finished(RealCall call)`
`int`	`getMaxRequests()`
`int`	`getMaxRequestsPerHost()`
`List<NewCall>`	`queuedCalls()`
`int`	`queuedCallsCount()`
`List<NewCall>`	`runningCalls()`
`int`	`runningCallsCount()`
`void`	`setIdleCallback(Runnable idleCallback)` 设置一个回调，以便每次调度程序变为空闲时调用(当运行的调用数量返回零时)
`void`	`setMaxRequests(int maxRequests)` 设置并发执行的最大请求数。上述请求在内存中排队，等待正在运行的调用完成如果在调用它时有超过`maxRequests`的请求在运行，那么这些请求将保持运行状态
`void`	`setMaxRequestsPerHost(int maxRequestsPerHost)` 设置每个主机并发执行的最大请求数。这将根据URL的主机名限制请求。注意，对单个IP地址的并发请求仍然可能超过这个限制:多个主机名可能共享一个IP地址，或者通过相同的HTTP代理进行路由如果在调用它时有超过`maxRequestsPerHost`的请求在运行，那么这些请求将保持运行状态

    设置并发执行的最大请求数。上述请求在内存中排队，等待正在运行的调用完成如果在调用它时有超过maxRequests的请求在运行，那么这些请求将保持运行状态
    
    Parameters:
    
    maxRequests - 最大请求数

public int getMaxRequestsPerHost()
```
  - setMaxRequestsPerHost
```
public void setMaxRequestsPerHost(int maxRequestsPerHost)
```
    设置每个主机并发执行的最大请求数。这将根据URL的主机名限制请求。注意，对单个IP地址的并发请求仍然可能超过这个限制:多个主机名可能共享一个IP地址，或者通过相同的HTTP代理进行路由如果在调用它时有超过maxRequestsPerHost的请求在运行，那么这些请求将保持运行状态
    
    Parameters:
    
    maxRequestsPerHost - 最大请求数
