Class ValveBase

java.lang.Object
org.apache.catalina.util.LifecycleBase
org.apache.catalina.util.LifecycleMBeanBase
org.apache.catalina.valves.ValveBase
All Implemented Interfaces:
MBeanRegistration, Contained, JmxEnabled, Lifecycle, Valve
Direct Known Subclasses:
AbstractAccessLogValve, AuthenticatorBase, CrawlerSessionManagerValve, ErrorReportValve, HealthCheckValve, JDBCAccessLogValve, JvmRouteBinderValve, LoadBalancerDrainingValve, PersistentValve, RemoteIpValve, ReplicationValve, RequestFilterValve, RewriteValve, SemaphoreValve, SingleSignOn, SSLValve, StuckThreadDetectionValve
public abstract class ValveBase extends LifecycleMBeanBase implements Contained, Valve
Convenience base class for implementations of the Valve interface. A subclass MUST implement an invoke() method to provide the required functionality, and MAY implement the Lifecycle interface to provide configuration management and lifecycle support.

      public Container getContainer()
      Description copied from interface: Contained
      Get the Container with which this instance is associated.
      Specified by:
      getContainer in interface Contained
      Returns:
      The Container with which this instance is associated or null if not associated with a Container

    • setContainer

      public void setContainer(Container container)
      Description copied from interface: Contained
      Set the Container with which this instance is associated.
      Specified by:
      setContainer in interface Contained
      Parameters:
      container - The Container instance with which this instance is to be associated, or null to disassociate this instance from any Container

    • isAsyncSupported

      public boolean isAsyncSupported()
      Specified by:
      isAsyncSupported in interface Valve

    • setAsyncSupported

      public void setAsyncSupported(boolean asyncSupported)

    • getNext

      public Valve getNext()
      Description copied from interface: Valve
      Returns the next Valve in this pipeline, or null if this is the last Valve in the pipeline.
      Specified by:
      getNext in interface Valve
      Returns:
      the next Valve in the pipeline containing this Valve, or null if this is the last Valve in the pipeline.

      Parameters:
      valve - The new next valve, or null if none

    • backgroundProcess

      public void backgroundProcess()
      Execute a periodic task, such as reloading, etc. This method will be invoked inside the classloading context of this container. Unexpected throwables will be caught and logged.

      The default implementation is NO-OP.

      Specified by:
      backgroundProcess in interface Valve

    • initInternal

      protected void initInternal() throws LifecycleException
      Description copied from class: LifecycleBase
      Subclasses implement this method to perform any instance initialisation required.
      Overrides:
      initInternal in class LifecycleMBeanBase
      Throws:
      LifecycleException - If the initialisation fails

    • startInternal

      protected void startInternal() throws LifecycleException
      Start this component and implement the requirements of LifecycleBase.startInternal().
      Specified by:
      startInternal in class LifecycleBase
      Throws:
      LifecycleException - if this component detects a fatal error that prevents this component from being used

    • stopInternal

      protected void stopInternal() throws LifecycleException
      Stop this component and implement the requirements of LifecycleBase.stopInternal().
      Specified by:
      stopInternal in class LifecycleBase
      Throws:
      LifecycleException - if this component detects a fatal error that prevents this component from being used

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • getObjectNameKeyProperties

      public String getObjectNameKeyProperties()
      Description copied from class: LifecycleMBeanBase
