jmri.beans.VetoableChangeSupport

jmri.managers.AbstractProxyManager<E>

Type Parameters:

E - the supported type of NamedBean

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.util.EventListener, PropertyChangeFirer, PropertyChangeProvider, SilenceablePropertyChangeProvider, VetoableChangeFirer, VetoableChangeProvider, Manager<E>, Manager.ManagerDataListener<E>, ProxyManager<E>

Direct Known Subclasses:

public abstract class AbstractProxyManager<E extends NamedBean>
extends VetoableChangeSupport
implements ProxyManager<E>, java.beans.PropertyChangeListener, Manager.ManagerDataListener<E>

Implementation of a Manager that can serves as a proxy for multiple system-specific implementations.

Automatically includes an Internal system, which need not be separately added any more.

Encapsulates access to the "Primary" manager, used by default, which is the first one provided.

Internally, this is done by using an ordered list of all non-Internal managers, plus a separate reference to the internal manager and default manager.

m - the Manager to add; if manager has already been added, it will not be added again

initInternal

protected Manager<E> initInternal()

makeInternalManager

protected abstract Manager<E> makeInternalManager()

Create specific internal manager as needed for concrete type.

Returns:

an internal manager

getNamedBean

public E getNamedBean(@Nonnull
                      java.lang.String name)

Locate an existing instance based on a name.

Specified by:

getNamedBean in interface Manager<E extends NamedBean>

Parameters:

name - User Name or System Name of the required NamedBean

Returns:

requested NamedBean object or null if none exists

getBySystemName

@CheckReturnValue
@CheckForNull
public E getBySystemName(@Nonnull
                         java.lang.String systemName)

Locate an existing instance based on a system name.

Specified by:

getBySystemName in interface Manager<E extends NamedBean>

Parameters:

systemName - System Name of the required NamedBean

Returns:

requested NamedBean object or null if none exists

getByUserName

@CheckReturnValue
@CheckForNull
public E getByUserName(@Nonnull
                       java.lang.String userName)

Locate an existing instance based on a user name.

Specified by:

getByUserName in interface Manager<E extends NamedBean>

Parameters:

userName - System Name of the required NamedBean

Returns:

requested NamedBean object or null if none exists

validateSystemNameFormat

@Nonnull
public java.lang.String validateSystemNameFormat(@Nonnull
                                                 java.lang.String systemName,
                                                 @Nonnull
                                                 java.util.Locale locale)

Validate the format of name, returning it unchanged if valid.

Although further restrictions may be added by system-specific implementations, at a minimum, the implementation must consider a name that does not start with the System Name prefix for this manager to be invalid, and must consider a name that is the same as the System Name prefix to be invalid.

Overriding implementations may rely on Manager.validSystemNameFormat(java.lang.String), however they must provide an actionable message in the thrown exception if that method does not return Manager.NameValidity.VALID. When overriding implementations of this method rely on validSystemNameFormat(), implementations of that method must not throw an exception, log an error, or otherwise disrupt the user.

This implementation locates a specific Manager based on the system name and validates against that. If no matching Manager exists, the default Manager attempts to validate the system name.

Specified by:

validateSystemNameFormat in interface Manager<E extends NamedBean>

Parameters:

systemName - the system name to validate

locale - the locale for a localized exception; this is needed for the JMRI web server, which supports multiple locales

Returns:

the unchanged value of the name parameter

validSystemNameFormat

public Manager.NameValidity validSystemNameFormat(@Nonnull
                                                  java.lang.String systemName)

Validate system name format. Locate a system specific Manager based on a system name.

Specified by:

validSystemNameFormat in interface Manager<E extends NamedBean>

Parameters:

systemName - the system name

Returns:

if a manager is found, return its determination of validity of system name format. Return INVALID if no manager exists.

public void dispose()

Free resources when no longer used. Specifically, remove all references to and from this object, so it can be garbage-collected.

Specified by:

dispose in interface Manager<E extends NamedBean>

deleteBean

public void deleteBean(@Nonnull
                       E s,
                       @Nonnull

                throws java.beans.PropertyVetoException

Method for a UI to delete a bean.

The UI should first request a "CanDelete", this will return a list of locations (and descriptions) where the bean is in use via throwing a VetoException, then if that comes back clear, or the user agrees with the actions, then a "DoDelete" can be called which inform the listeners to delete the bean, then it will be deregistered and disposed of.

If a property name of "DoNotDelete" is thrown back in the VetoException then the delete process should be aborted.

Specified by:

deleteBean in interface Manager<E extends NamedBean>

Parameters:

s - The NamedBean to be deleted

property - The programmatic name of the request. "CanDelete" will enquire with all listeners if the item can be deleted. "DoDelete" tells the listener to delete the item

Throws:

java.beans.PropertyVetoException - If the recipients wishes the delete to be aborted (see above)

See Also:

Manager.addDataListener(ManagerDataListener)

contentsChanged

public void contentsChanged(Manager.ManagerDataEvent<E> e)

Sent when the contents of the list has changed in a way that's too complex to characterize with the previous methods. From Manager.ManagerDataListener, receives notifications from underlying managers.

Specified by:

contentsChanged in interface Manager.ManagerDataListener<E extends NamedBean>

Parameters:

e - encapsulates event information

intervalAdded

public void intervalAdded(Manager.ManagerDataEvent<E> e)

Sent after the indices in the index0,index1 interval have been inserted in the data model. From Manager.ManagerDataListener, receives notifications from underlying managers.

Specified by:

Sent after the indices in the index0,index1 interval have been removed from the data model. From Manager.ManagerDataListener, receives notifications from underlying managers.

Specified by:

intervalRemoved in interface Manager.ManagerDataListener<E extends NamedBean>

Parameters:

e - encapsulates the event information

setDataListenerMute

public void setDataListenerMute(boolean m)

Temporarily suppress DataListener notifications.

This avoids O(N^2) behavior when doing bulk updates, i.e. when loading lots of Beans. Note that this is (1) optional, in the sense that the manager is not required to mute and (2) if present, its' temporary, in the sense that the manager must do a cumulative notification when done.

Specified by:

setDataListenerMute in interface Manager<E extends NamedBean>

Parameters:

m - true if notifications should be suppressed; false otherwise
