Enum InitMilestone

java.lang.Enum<InitMilestone>

hudson.init.InitMilestone

All Implemented Interfaces:

Serializable, Comparable<InitMilestone>, org.jvnet.hudson.reactor.Milestone

public enum InitMilestone
extends Enum<InitMilestone>
implements org.jvnet.hudson.reactor.Milestone

Various key milestone in the initialization process of Hudson.

Plugins can use these milestones to execute their initialization at the right moment (in addition to defining their own milestones by implementing Milestone.

These milestones are achieve in this order.

Enum Constant Summary

Enum Constants

Enum Constant and Description
COMPLETED The very last milestone This is used in Initializer.before() since annotations cannot have null as the default value.
EXTENSIONS_AUGMENTED By this milestone, all programmatically constructed extension point implementations should be added.
JOB_LOADED By this milestone, all jobs and their build records are loaded from disk.
PLUGINS_LISTED By this milestone, all plugins metadata are inspected and their dependencies figured out.
PLUGINS_PREPARED By this milestone, all plugin metadata are loaded and its classloader set up.
PLUGINS_STARTED By this milestone, all plugins start executing, all extension points loaded, descriptors instantiated and loaded.
STARTED The very first milestone that gets achieved without doing anything.

Enum Constant Detail

STARTED

public static final InitMilestone STARTED

The very first milestone that gets achieved without doing anything. This is used in Initializer.after() since annotations cannot have null as the default value.

PLUGINS_LISTED

public static final InitMilestone PLUGINS_LISTED

By this milestone, all plugins metadata are inspected and their dependencies figured out.

PLUGINS_PREPARED

public static final InitMilestone PLUGINS_PREPARED

By this milestone, all plugin metadata are loaded and its classloader set up.

PLUGINS_STARTED

public static final InitMilestone PLUGINS_STARTED

By this milestone, all plugins start executing, all extension points loaded, descriptors instantiated and loaded.

This is a separate milestone from PLUGINS_PREPARED since the execution of a plugin often involves finding extension point implementations, which in turn require all the classes from all the plugins to be loadable.

EXTENSIONS_AUGMENTED

public static final InitMilestone EXTENSIONS_AUGMENTED

By this milestone, all programmatically constructed extension point implementations should be added.

JOB_LOADED

public static final InitMilestone JOB_LOADED

By this milestone, all jobs and their build records are loaded from disk.

COMPLETED

public static final InitMilestone COMPLETED

The very last milestone This is used in Initializer.before() since annotations cannot have null as the default value.

Method Detail

values

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

Returns:

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

valueOf

public static InitMilestone 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

ordering

public static org.jvnet.hudson.reactor.TaskBuilder ordering()

Creates a set of dummy tasks to enforce ordering among InitMilestones.

toString

public String toString()

Overrides:

toString in class Enum<InitMilestone>
