| StandardPipeline | | public class StandardPipeline implements Pipeline,Contained,Lifecycle(Code) | | Standard implementation of a processing Pipeline that will invoke
a series of Valves that have been configured to be called in order. This
implementation can be used for any type of Container.
IMPLEMENTATION WARNING - This implementation assumes that no
calls to addValve() or removeValve are allowed
while a request is currently being processed. Otherwise, the mechanism
by which per-thread state is maintained will need to be modified.

Container, including the basic Valve (if any). | | public void | removeLifecycleListener(LifecycleListener listener)
Remove a lifecycle event listener from this component. | | public void | removeValve(Valve valve)
Remove the specified Valve from the pipeline associated with this
Container, if it is found; otherwise, do nothing. | | public void | setBasic(Valve valve)
Set the Valve instance that has been distinguished as the basic
Valve for this Pipeline (if any). | | public void | setContainer(Container container)

| basic | | protected Valve basic(Code) | | The basic Valve (if any) associated with this Pipeline.
|
| container | | protected Container container(Code) | | The Container with which this Pipeline is associated.
|
| first | | protected Valve first(Code) | | The first valve associated with this Pipeline.
|
| info | | protected String info(Code) | | Descriptive information about this implementation.
|
| started | | protected boolean started(Code) | | Has this component been started yet?
|
| StandardPipeline | | public StandardPipeline()(Code) | | Construct a new StandardPipeline instance with no associated Container.
|
| StandardPipeline | | public StandardPipeline(Container container)(Code) | | Construct a new StandardPipeline instance that is associated with the
specified Container.
Parameters:
container - The container we should be associated with |
| addLifecycleListener | | public void addLifecycleListener(LifecycleListener listener)(Code) | | Add a lifecycle event listener to this component.
Parameters:
listener - The listener to add |
| addValve | | public void addValve(Valve valve)(Code) | | Add a new Valve to the end of the pipeline associated with this
Container. Prior to adding the Valve, the Valve's
setContainer() method will be called, if it implements
Contained, with the owning Container as an argument.
The method may throw an
IllegalArgumentException if this Valve chooses not to
be associated with this Container, or IllegalStateException
if it is already associated with a different Container.
Parameters:
valve - Valve to be added
exception:
IllegalArgumentException - if this Container refused toaccept the specified Valve
exception:
IllegalArgumentException - if the specifie Valve refuses to beassociated with this Container
exception:
IllegalStateException - if the specified Valve is alreadyassociated with a different Container |
| findLifecycleListeners | | public LifecycleListener[] findLifecycleListeners()(Code) | | Get the lifecycle listeners associated with this lifecycle. If this
Lifecycle has no listeners registered, a zero-length array is returned.
|
| getBasic | | public Valve getBasic()(Code) | | Return the Valve instance that has been distinguished as the basic
Valve for this Pipeline (if any).
|
| getContainer | | public Container getContainer()(Code) | | Return the Container with which this Pipeline is associated.
|
| getInfo | | public String getInfo()(Code) | | Return descriptive information about this implementation class.
|
| getValves | | public Valve[] getValves()(Code) | | Return the set of Valves in the pipeline associated with this
Container, including the basic Valve (if any). If there are no
such Valves, a zero-length array is returned.
|
| removeLifecycleListener | | public void removeLifecycleListener(LifecycleListener listener)(Code) | | Remove a lifecycle event listener from this component.
Parameters:
listener - The listener to remove |
| removeValve | | public void removeValve(Valve valve)(Code) | | Remove the specified Valve from the pipeline associated with this
Container, if it is found; otherwise, do nothing. If the Valve is
found and removed, the Valve's setContainer(null) method
will be called if it implements Contained.
Parameters:
valve - Valve to be removed |
| setBasic | | public void setBasic(Valve valve)(Code) | | Set the Valve instance that has been distinguished as the basic
Valve for this Pipeline (if any). Prioer to setting the basic Valve,
the Valve's setContainer() will be called, if it
implements Contained, with the owning Container as an
argument. The method may throw an IllegalArgumentException
if this Valve chooses not to be associated with this Container, or
IllegalStateException if it is already associated with
a different Container.
Parameters:
valve - Valve to be distinguished as the basic Valve |
| setContainer | | public void setContainer(Container container)(Code) | | Set the Container with which this Pipeline is associated.
Parameters:
container - The new associated container |
| start | | public synchronized void start() throws LifecycleException(Code) | | Prepare for active use of the public methods of this Component.
exception:
LifecycleException - if this component detects a fatal errorthat prevents it from being started |
| stop | | public synchronized void stop() throws LifecycleException(Code) | | Gracefully shut down active use of the public methods of this Component.
exception:
LifecycleException - if this component detects a fatal errorthat needs to be reported |
