方法详细信息

getServer

public Server getServer()

指定者：

接口 Connector 中的 getServer

setServer

public void setServer(Server server)

指定者：

getThreadPool

public ThreadPool getThreadPool()

setThreadPool

public void setThreadPool(ThreadPool pool)

Set the ThreadPool. The threadpool passed is added via AggregateLifeCycle.addBean(Object) so that it's lifecycle may be managed as a AggregateLifeCycle.

参数：

pool - the threadPool to set

setHost

public void setHost(String host)

从接口 Connector 复制的描述

Set the hostname of the interface to bind to.

指定者：

接口 Connector 中的 setHost

参数：

host - The hostname representing the interface to which this connector will bind, or null for all interfaces.

public String getHost()

指定者：

返回：

The hostname representing the interface to which this connector will bind, or null for all interfaces.

setPort

getMaxIdleTime

public int getMaxIdleTime()

指定者：

接口 Connector 中的 getMaxIdleTime

返回：

Returns the maxIdleTime.

setMaxIdleTime

public void setMaxIdleTime(int maxIdleTime)

Set the maximum Idle time for a connection, which roughly translates to the Socket.setSoTimeout(int) call, although with NIO implementations other mechanisms may be used to implement the timeout. The max idle time is applied:

• When waiting for a new request to be received on a connection
• When reading the headers and content of a request
• When writing the headers and content of a response

Jetty interprets this value as the maximum time between some progress being made on the connection. So if a single byte is read or written, then the timeout (if implemented by jetty) is reset. However, in many instances, the reading/writing is delegated to the JVM, and the semantic is more strictly enforced as the maximum time a single read/write operation can take. Note, that as Jetty supports writes of memory mapped file buffers, then a write may take many 10s of seconds for large content written to a slow device.

Previously, Jetty supported separate idle timeouts and IO operation timeouts, however the expense of changing the value of soTimeout was significant, so these timeouts were merged. With the advent of NIO, it may be possible to again differentiate these values (if there is demand).

isLowResources

public boolean isLowResources()

从接口 Connector 复制的描述

Check if low on resources. For most connectors, low resources is measured by calling ThreadPool.isLowOnThreads() on the connector threadpool or the server threadpool if there is no connector threadpool.

For blocking connectors, low resources is used to trigger usage of Connector.getLowResourceMaxIdleTime() for the timeout of an idle connection.

for non-blocking connectors, the number of connections is used instead of this method, to select the timeout of an idle connection.

For all connectors, low resources is used to trigger the usage of Connector.getLowResourceMaxIdleTime() for read and write operations.

指定者：

接口 Connector 中的 isLowResources

返回：

true if this connector is low on resources.
