类 PolicyMonitor

java.lang.Object
  org.eclipse.jetty.util.component.AbstractLifeCycle
      org.eclipse.jetty.policy.PolicyMonitor

所有已实现的接口：

LifeCycle

public abstract class PolicyMonitor
extends AbstractLifeCycle

PolicyMonitor watches a directory for files ending in the *.policy extension, loads them and detects when they change. PolicyGrants are peeped out the onPolicyChange method to whoever is using this monitor.

构造方法摘要

PolicyMonitor()

PolicyMonitor(String directory)
construtor with a predetermined directory to monitor

方法摘要

protected void	doStart() called by the abstract lifecycle to start the monitor
protected void	doStop() called by the abstract life cycle to turn off the monitor
int	getScanCount() gets the number of times the scan has been run
int	getScanInterval() gets the scanner interval
boolean	isInitialized() true of the monitor is initialized, meaning that at least one scan cycle has completed and any policy grants found have been chirped
boolean	isReloadEnabled() true of reload is enabled, false otherwise
abstract void	onPolicyChange(PolicyBlock grant) implemented by the user of the policy monitor to handle custom logic related to the usage of the policy grant instance/s.
void	setPolicyDirectory(String directory) set the policy directory to scan on a non-running monitor
void	setReload(boolean reload) sets the monitor to reload or not, but only if the monitor isn't already running TODO this doesn't really _have_ to be on a non-running monitor
void	setScanInterval(int scanInterval) sets the scanner interval on a non-running instance of the monitor
void	waitForScan() initiates a scan and blocks until it has been completed

构造方法详细信息

PolicyMonitor

public PolicyMonitor()

empty constructor

PolicyMonitor

public PolicyMonitor(String directory)

construtor with a predetermined directory to monitor

参数：

directory -

方法详细信息

setPolicyDirectory

public void setPolicyDirectory(String directory)

set the policy directory to scan on a non-running monitor

参数：

directory -

getScanInterval

public int getScanInterval()

gets the scanner interval

返回：

the scan interval

setScanInterval

public void setScanInterval(int scanInterval)

sets the scanner interval on a non-running instance of the monitor

参数：

scanInterval - in seconds

另请参见：

Scanner.setScanInterval(int)

isInitialized

public boolean isInitialized()

true of the monitor is initialized, meaning that at least one scan cycle has completed and any policy grants found have been chirped

返回：

true if initialized

getScanCount

public int getScanCount()

gets the number of times the scan has been run

返回：

scan count

waitForScan

public void waitForScan()
                 throws Exception

initiates a scan and blocks until it has been completed

抛出：

Exception

isReloadEnabled

public boolean isReloadEnabled()

true of reload is enabled, false otherwise

返回：

true if reload is enabled

setReload

public void setReload(boolean reload)

sets the monitor to reload or not, but only if the monitor isn't already running TODO this doesn't really _have_ to be on a non-running monitor

参数：

reload -

doStart

protected void doStart()
                throws Exception

called by the abstract lifecycle to start the monitor

覆盖：

类 AbstractLifeCycle 中的 doStart

抛出：

Exception

doStop

protected void doStop()
               throws Exception

called by the abstract life cycle to turn off the monitor

覆盖：

类 AbstractLifeCycle 中的 doStop

抛出：

Exception

onPolicyChange

public abstract void onPolicyChange(PolicyBlock grant)

implemented by the user of the policy monitor to handle custom logic related to the usage of the policy grant instance/s.

参数：

grant -
