@PublicApi public class ComponentAccessor extends Object
Normally, developers should get the dependencies injected into the constructor of the calling class by Pico; however, this utility provides access for when that is impossible or impractical. Examples include:
Plugin developers that are trying to figure out how to fix an IllegalStateException
that they
are getting in a unit test should read the documentation for the MockComponentWorker
in the
jira-tests
artifact for instructions.

public static <T> Optional<T> getComponentSafely(Class<T> componentClass)
This is equivalent to checking ComponentManager.getInstance().getState().isContainerInitialised()
before retrieving the component and using Optional.empty()
for all cases of being unable to resolve
it.
This paranoid usage is mainly of interest to very low-level code, such as custom Seraph authenticators
or web filters, that might get accessed during system initialization or catastrophic error reporting
(404.jsp
, error500.jsp
, or startup.jsp
for example). Plugins generally should
not have to worry about this because the Pico container is initialized before the plugin system is
started.

In practise, this is the same as getComponentOfType(Class)
except it will fail faster if the
given Class is not a known component key (it also has a shorter and more meaningful name).
Please note that this method only gets components from JIRA's core Pico Container. That is, it retrieves core components and components declared in Plugins1 plugins, but not components declared in Plugins2 plugins.

Serializable
lazy reference to the core component which is stored in JIRA's
Dependency Injection container under the key that is the given class.
WARNING: Component references obtained in this way must not be held past the lifetime
of the Pico container, which is thrown away during a full system restore (import). Doing so causes the
previous incarnation of the system to bleed across, leading to leaked memory, poor performance, and even
inconsistent behaviour as components from the two separate Pico containers accidentally interact. This
warning is generally not important to plugin developers, but should be respected by anyone working within
jira-core
, particularly when messing with filters, seraph authenticators, and other globally
static objects.

ServiceTracker
or other similar enhanced access methods available through OSGi and
through the plugin system in general. Since v7.0.0.Serializable
lazy reference to the OSGi component under the key that is the

WARNING: This probably should not be used by any plugin developer. It effectively caches
the result of calling getOSGiComponentInstanceOfType(Class)
, and as its documentation states, this
is dangerous.

public static <T> T getComponentOfType(Class<T> componentClass)
First it tries to find the component using the given Class as a key (like getComponent(Class)
),
however, if this fails then it will try to find a unique component that implements/extends the given Class.
This seems unlikely to be useful, but is included for now, for completeness and backward compatibility.
Please note that this method only gets components from JIRA's core Pico Container. That is, it retrieves core components and components declared in Plugins1 plugins, but not components declared in Plugins2 plugins.

public static <T> T getOSGiComponentInstanceOfType(Class<T> componentClass)
It is important to note that this only works for public components. That is components with public="true"
declared in their XML configuration. This means that they are available for other plugins to import.
A example use case for this method is the dashboards plugin. In several areas in JIRA we may want to
render gadgets via the GadgetViewFactory
. Whilst the interface for this
component is available in JIRA core, the implementation is provided by the dashboards OSGi bundle. This method
will allow us to access it.
