Method Detail

get

<T> T get(String key)

Alias method performing the lookup, here to simplify syntax when called from dynamic languages.

lookupObject

<T> T lookupObject(String key)

Look up a single object by name.

Returns:

object or null if not found

lookupObjects

<T> Collection<T> lookupObjects(Class<T> type)

Look up all objects of a given type.

Returns:

collection of objects or empty collection if none found

lookupObjectsForLifecycle

<T> Collection<T> lookupObjectsForLifecycle(Class<T> type)

Look up all objects of a given type that lifecycle should be applied to. This method differs from lookupObjects(Class) in that it allows implementations to provide an alternative implementation of lookup for lifecycle. For example only returning pre-existing objects and not creating new ones on the fly.

Returns:

collection of objects or empty collection if none found

lookupObject

<T> T lookupObject(Class<T> clazz)
               throws RegistrationException

Look up a single object by type.

Returns:

object or null if not found

Throws:

RegistrationException - if more than one object is found.

lookupByType

<T> Map<String,T> lookupByType(Class<T> type)

Returns:

key/object pairs

registerObject

void registerObject(String key,
                    Object value)
                    throws RegistrationException

Registers an object in the registry with a key.

Parameters:

key - the key to store the value against. This is a non-null value

value - the object to store in the registry. This is a non-null value

Throws:

RegistrationException - if an object with the same key already exists

registerObject

void registerObject(String key,
                    Object value,
                    Object metadata)
                    throws RegistrationException

Registers an object in the registry with a key.

Parameters:

key - the key to store the value against. This is a non-null value

value - the object to store in the registry. This is a non-null value

metadata - an implementation specific argument that can be passed into the method

Throws:

RegistrationException - if an object with the same key already exists

registerObjects

void registerObjects(Map<String,Object> objects)
                     throws RegistrationException

Registers a Map of objects into the registry

Parameters:

objects - a map of key value pairs, each will individually be registered in the registry

Throws:

RegistrationException - if an object with the same key already exists

unregisterObject

void unregisterObject(String key)
                      throws RegistrationException

Will remove an object by name from the registry. By default the registry must apply all remaining lifecycle phases to the object when it is removed.

Parameters:

key - the name or key of the object to remove from the registry

Throws:

RegistrationException - if there is a problem unregistering the object. Typically this will be because the object's lifecycle threw an exception

unregisterObject

void unregisterObject(String key,
                      Object metadata)
                      throws RegistrationException

Will remove an object by name from the registry. By default the registry must apply all remaining lifecycle phases to the object when it is removed.

Parameters:

key - the name or key of the object to remove from the registry

metadata - an implementation specific argument that can be passed into the method

Throws:

RegistrationException - if there is a problem unregistering the object. Typically this will be because the object's lifecycle threw an exception

getRegistryId

String getRegistryId()

fireLifecycle

void fireLifecycle(String phase)
                   throws LifecycleException

Throws:

LifecycleException

isReadOnly

boolean isReadOnly()

isRemote

boolean isRemote()
