Enum Constant Detail

OPENING_ARCHIVE

public static final DeploymentTracing.AppStage OPENING_ARCHIVE

Activities related to reading contents of application archive. Component refers to type of service being looked up in the server.

TRANSFORM_ARCHIVE

public static final DeploymentTracing.AppStage TRANSFORM_ARCHIVE

Activities related to transforming the contents of application archive from javax.* to jakarta.* and vice-versa.

VALIDATE_TARGET

public static final DeploymentTracing.AppStage VALIDATE_TARGET

Validate whether deployment is fit for specified target. Component command validates correctness of the command parameter, component registry validates possibility of deployment to target instance(s).

CREATE_DEPLOYMENT_CONTEXT

public static final DeploymentTracing.AppStage CREATE_DEPLOYMENT_CONTEXT

Creation of deployment context. Deployment context aggregates all information on a deployment process, and there are two phases with two distinct contexts - initial and full.

PROCESS_EVENTS

public static final DeploymentTracing.AppStage PROCESS_EVENTS

Processing of event hooks. During deployment, the process exposes several extensions points by means of event bus. The component of this span lists EventTypes.name of the event being sent and synchronously processed by respective hooks.

DETERMINE_APP_NAME

public static final DeploymentTracing.AppStage DETERMINE_APP_NAME

Determine name of an app. App name is looked up in variety of descriptors and algorithms defined by the specifications. Component distinguishes these parts of determination.

CLEANUP

public static final DeploymentTracing.AppStage CLEANUP

Cleanup deletes data of inactive application. Is can also cause surprising delayes due to filesystem locks (usually on Windows). Components hints on server subdirectory being cleaned (applications or generated).

SWITCH_VERSIONS

public static final DeploymentTracing.AppStage SWITCH_VERSIONS

Coordinate version switch. Version switching involves disabling previous version of application on the target, and that can take substantial time

PREPARE

public static final DeploymentTracing.AppStage PREPARE

Preparation of server components that will handle the application and validation of application. Context of the event points at container being prepared, and component at type of server component in preparation. An example of preparation step is EclipseLink's class weaving.

INITIALIZE

public static final DeploymentTracing.AppStage INITIALIZE

Final step before starting an application. Good example of initialization step is starting up EJB Timer Service when needed.

START

public static final DeploymentTracing.AppStage START

Starting application. This is where application code gets first executed, all of the application-defined components declared to run at startup are run.

REGISTRATION

public static final DeploymentTracing.AppStage REGISTRATION

Update domain configuration with information on new application.

CLASS_SCANNING

public static final DeploymentTracing.AppStage CLASS_SCANNING

Collect information on annotated types.

CONTAINER_START

public static final DeploymentTracing.AppStage CONTAINER_START

First start of a subsystem handling specific container.

CREATE_CLASSLOADER

public static final DeploymentTracing.AppStage CREATE_CLASSLOADER

Creation of application classloader. This is usually followed by making this classloader a context classloader for deploying thread.

LOAD

public static final DeploymentTracing.AppStage LOAD

Load the application code and prepare runtime structures.

Method Detail

values

public static DeploymentTracing.AppStage[] 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 (DeploymentTracing.AppStage c : DeploymentTracing.AppStage.values())
    System.out.println(c);

Returns:

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

valueOf

public static DeploymentTracing.AppStage 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
