Class StandardEngine

  • All Implemented Interfaces:
    javax.management.MBeanRegistration, Container, Engine, JmxEnabled, Lifecycle
    public class StandardEngine
extends ContainerBase
implements Engine
    Standard implementation of the Engine interface. Each child container must be a Host implementation to process the specific fully qualified host name of that virtual host.

        Returns:
        the default host name for this Engine.

      • setDefaultHost

        public void setDefaultHost​(java.lang.String host)
        Description copied from interface: Engine
        Set the default hostname for this Engine.
        Specified by:
        setDefaultHost in interface Engine
        Parameters:
        host - The new default host

      • setJvmRoute

        public void setJvmRoute​(java.lang.String routeId)
        Description copied from interface: Engine
        Set the JvmRouteId for this engine.
        Specified by:
        setJvmRoute in interface Engine
        Parameters:
        routeId - the (new) JVM Route ID. Each Engine within a cluster must have a unique JVM Route ID.

      • getJvmRoute

        public java.lang.String getJvmRoute()
        Specified by:
        getJvmRoute in interface Engine
        Returns:
        the JvmRouteId for this engine.

      • getService

        public Service getService()
        Specified by:
        getService in interface Engine
        Returns:
        the Service with which we are associated (if any).

      • setService

        public void setService​(Service service)
        Description copied from interface: Engine
        Set the Service with which we are associated (if any).
        Specified by:
        setService in interface Engine
        Parameters:
        service - The service that owns this Engine

      • addChild

        public void addChild​(Container child)
        Add a new child Container to those associated with this Container, if supported. Prior to adding this Container to the set of children, the child's setParent() method must be called, with this Container as an argument. This method may throw an IllegalArgumentException if this Container chooses not to be attached to the specified Container, in which case it is not added

        The child must be an implementation of Host.

        Specified by:
        addChild in interface Container
        Overrides:
        addChild in class ContainerBase
        Parameters:
        child - New child Container to be added

      • setParent

        public void setParent​(Container container)
        Disallow any attempt to set a parent for this Container, since an Engine is supposed to be at the top of the Container hierarchy.
        Specified by:
        setParent in interface Container
        Overrides:
        setParent in class ContainerBase
        Parameters:
        container - Proposed parent Container

      • logAccess

        public void logAccess​(Request request,
                      Response response,
                      long time,
                      boolean useDefault)
        Log a request/response that was destined for this container but has been handled earlier in the processing chain so that the request/response still appears in the correct access logs.

        Override the default implementation. If no access log is defined for the Engine, look for one in the Engine's default host and then the default host's ROOT context. If still none is found, return the default NoOp access log.

        Specified by:
        logAccess in interface Container
        Overrides:
        logAccess in class ContainerBase
        Parameters:
        request - Request (associated with the response) to log
        response - Response (associated with the request) to log
        time - Time taken to process the request/response in nanoseconds (use 0 if not known)
        useDefault - Flag that indicates that the request/response should be logged in the engine's default access log

        protected java.lang.String getObjectNameKeyProperties()
        Description copied from class: LifecycleMBeanBase
        Allow subclasses to specify the key properties component of the ObjectName that will be used to register this component.
        Specified by:
        getObjectNameKeyProperties in class LifecycleMBeanBase
        Returns:
        The string representation of the key properties component of the desired ObjectName

      • getDomainInternal

        protected java.lang.String getDomainInternal()
        Description copied from class: LifecycleMBeanBase
        Method implemented by subclasses to identify the domain in which MBeans should be registered.
        Overrides:
        getDomainInternal in class ContainerBase
        Returns:
        The name of the domain to use to register MBeans.
