Enum LifecycleStage

java.lang.Object

java.lang.Enum<LifecycleStage>

net.sourceforge.stripes.controller.LifecycleStage

All Implemented Interfaces:

Serializable, Comparable<LifecycleStage>

public enum LifecycleStage
extends Enum<LifecycleStage>

Describes the major stages that form the Stripes request processing lifecycle. These stages are enumerated here primarily because they are the points around which execution can be intercepted using the Stripes Interceptor system.

Since:

Stripes 1.3

Enum Constant Detail

ActionBeanResolution

public static final LifecycleStage ActionBeanResolution

First major lifecycle stage. Involves the location of the ActionBean class that is bound to the URL being requested, and usually also the creation of a new instance of that class.

HandlerResolution

public static final LifecycleStage HandlerResolution

Second major lifecycle stage. Involves the determination of the event name in the request (if there is one), and the location of the Method which handles the even.

BindingAndValidation

public static final LifecycleStage BindingAndValidation

Third major lifecycle stage. Involves the processing of all validations specified through @Validate annotations as well as the type conversion of request parameters and their binding to the ActionBean.

CustomValidation

public static final LifecycleStage CustomValidation

Fourth major lifecycle stage. Involves the execution of any custom validation logic exposed by the ActionBean.

EventHandling

public static final LifecycleStage EventHandling

Fifth major lifecycle stage. The actual execution of the event handler method. Only occurs when the prior stages have produced no persistent validation errors.

ResolutionExecution

public static final LifecycleStage ResolutionExecution

Sixth major lifecycle stage. Is executed any time a Resolution is executed, either as the outcome of an event handler, or because some other mechanism short circuits processing by returning a Resolution.

RequestInit

public static final LifecycleStage RequestInit

Executed before any processing occurs on the request. No Stripes processing is associated with this stage. It is simply provided as a hook for interceptors.

RequestComplete

public static final LifecycleStage RequestComplete

Final lifecycle stage. Executes in the finally block of the request so it will always be called when a request terminates regardless of any other conditions. This is only useful for cleaning up because Resolution execution has already occurred.

Method Detail

values

public static LifecycleStage[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (LifecycleStage c : LifecycleStage.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static LifecycleStage valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
