Specified by:

doInitialise in class AbstractRegistry

Throws:

InitialisationException

doDispose

applyProcessors

protected Map applyProcessors(Map<String,Object> objects)

registerObjects

public void registerObjects(Map objects)
                     throws RegistrationException

Description copied from interface: Registry

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

lookupByType

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

Returns:

key/object pairs

lookupObject

public <T> T lookupObject(String key)

Description copied from interface: Registry

Look up a single object by name.

Returns:

object or null if not found

lookupObjects

public <T> Collection<T> lookupObjects(Class<T> returntype)

Description copied from interface: Registry

Look up all objects of a given type.

Returns:

collection of objects or empty collection if none found

registerObject

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

Allows for arbitary registration of transient objects

Parameters:

key -

value -

Throws:

RegistrationException - if an object with the same key already exists

registerObject

public void registerObject(String key,
                           Object object,
                           Object metadata)
                    throws RegistrationException

Allows for arbitrary registration of transient objects

Parameters:

key -

object - 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

checkDisposed

protected void checkDisposed()
                      throws RegistrationException

Throws:

RegistrationException

hasFlag

protected boolean hasFlag(Object metaData,
                          int flag)

unregisterObject

public void unregisterObject(String key,
                             Object metadata)
                      throws RegistrationException

Will remove an object by name from the registry. By default the registry will 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 - Meta data flags supported are org.mule.api.registry.MuleRegistry.LIFECYCLE_BYPASS_FLAG

Throws:

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

unregisterObject

public void unregisterObject(String key)
                      throws RegistrationException

Description copied from interface: Registry

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

isReadOnly

public boolean isReadOnly()

isRemote

public boolean isRemote()
