jmri.beans.UnboundBean

jmri.beans.Bean

jmri.util.prefs.AbstractPreferencesManager

All Implemented Interfaces:

PropertyChangeListener, EventListener, BeanInterface, PropertyChangeFirer, PropertyChangeProvider, JmriServiceProviderInterface, PreferencesManager, JTablePersistenceManager

public class JmriJTablePersistenceManager
extends AbstractPreferencesManager
implements JTablePersistenceManager, PropertyChangeListener

Default implementation of JTablePersistenceManager. The column preferredWidth retained for a column is the TableColumn.getPreferredWidth(), since this preferredWidth is available before the table column is rendered by Swing.

Method Details

persist

public void persist(@Nonnull
 JTable table,
 boolean resetState)
             throws IllegalArgumentException,
NullPointerException

Persist the user interface state for a table. The name returned by Component.getName() is used to persist the table, so ensure the name is set such that it can be retrieved by the same name in a later JMRI execution.

Note that the current state of the table, if not already persisted, at the time of this call is retained as the table state unless resetState is true.

Using this method with resetState set to true is the same as JTablePersistenceManager.resetState(javax.swing.JTable) immediately prior to calling JTablePersistenceManager.persist(javax.swing.JTable).

Persisting a table that is already persisted may cause the persistence state to be updated, but will not cause additional listeners to be added to the table.

Specified by:

persist in interface JTablePersistenceManager

Parameters:

table - the table to persist

resetState - reset the table to the stored state if true; retain the current state if false

Throws:

IllegalArgumentException - if another table instance is already persisted by the same name

NullPointerException - if the table name is null

stopPersisting

public void stopPersisting(JTable table)

Description copied from interface: JTablePersistenceManager

Stop persisting the table. This does not clear the persistence state, but merely causes the JTablePersistenceManager to stop listening to the table. No error is thrown if the table state was not being persisted.

Specified by:

stopPersisting in interface JTablePersistenceManager

Parameters:

table - the table to stop persisting

clearState

public void clearState(JTable table)

Description copied from interface: JTablePersistenceManager

Remove the persistent state for a table from the cache. This does not cause the JTablePersistanceManager to stop persisting the table.

Specified by:

clearState in interface JTablePersistenceManager

Parameters:

table - the table to clear

cacheState

public void cacheState(JTable table)

Description copied from interface: JTablePersistenceManager

Add the current state for a table to the cache. This does not cause the JTablePersistanceManager to start persisting the table.

Specified by:

cacheState in interface JTablePersistenceManager

Parameters:

table - the table to cache

resetState

public void resetState(JTable table)

Description copied from interface: JTablePersistenceManager

Reset the table state to the cached state. This does not cause the JTablePersistanceManager to start persisting the table.

Specified by:

resetState in interface JTablePersistenceManager

Parameters:

table - the table to reset

setDirty

protected void setDirty(boolean dirty)

Set dirty (needs to be saved) state. Protected so that subclasses can manipulate this state.

Parameters:

dirty - true if needs to be saved

isDirty

protected boolean isDirty()

Get dirty (needs to be saved) state. Protected so that subclasses can manipulate this state.

Returns:

true if needs to be saved

setPaused

public void setPaused(boolean paused)

Description copied from interface: JTablePersistenceManager

Pause saving persistence data to storage. If setting paused to false, pending persistence data is written immediately.

Specified by:

setPaused in interface JTablePersistenceManager

Parameters:

paused - true if saving persistence data should be paused; false otherwise.

isPaused

public boolean isPaused()

Description copied from interface: JTablePersistenceManager

Determine if saving persistence data is paused.

Specified by:

isPaused in interface JTablePersistenceManager

Returns:

true if saving persistence data is paused; false otherwise.

initialize

public void initialize(Profile profile)
                throws InitializationException

Description copied from interface: PreferencesManager

Initialize the PreferencesManager with preferences associated with the provided Profile.

Implementing classes should throw an InitializationException with a user readable localized message, since it most likely be displayed to the user. Implementing classes will still want to ensure that PreferencesManager.isInitialized(jmri.profile.Profile) or PreferencesManager.isInitializedWithExceptions(jmri.profile.Profile) return true if throwing an InitializationException to ensure that the provider is not repeatedly initialized.

Specified by:

initialize in interface PreferencesManager

Parameters:

profile - the configuration profile used for this initialization; may be null to initialize for this user regardless of profile

Throws:

InitializationException - if the user needs to be notified of an issue that prevents regular use of the application

savePreferences

public void savePreferences(Profile profile)

Description copied from interface: PreferencesManager

Save the preferences that this provider manages for the provided Profile.

Specified by:

savePreferences in interface PreferencesManager

Parameters:

profile - the profile associated with the preferences to save; may be null to save preferences that apply to the current user regardless of profile

getProvides

@Nonnull
public Set<Class<?>> getProvides()

Description copied from class: AbstractPreferencesManager

Get the set of Classes that this PreferencesManager can be registered as a provider of in the InstanceManager.

This implementation returns the class of the object against which this method is called.

Specified by:

getProvides in interface PreferencesManager

Overrides:

getProvides in class AbstractPreferencesManager

Returns:

A set or list of classes. If this PreferencesManager provides an instance of no other Interfaces or abstract Classes than PreferencesManager, return an empty set instead of null.

setPersistedState

protected void setPersistedState(@Nonnull
 String table,
 @Nonnull
 String column,
 int order,
 int width,
 SortOrder sort,
 boolean hidden)

Set the persisted state for the given column in the given table. The persisted state is not saved until savePreferences(jmri.profile.Profile) is called.

Parameters:

table - the table name

column - the column name

order - order of the column

width - column preferredWidth

sort - how the column is sorted

hidden - true if column is hidden

Throws:

NullPointerException - if either name is null

isPersistenceDataRetained

public boolean isPersistenceDataRetained(JTable table)

Description copied from interface: JTablePersistenceManager

Determine if persistence data is being held for a table.

Specified by:

isPersistenceDataRetained in interface JTablePersistenceManager

Parameters:

table - the table to check against

Returns:

true if the table has persistence data; false otherwise

isPersistenceDataRetained

public boolean isPersistenceDataRetained(String name)

Description copied from interface: JTablePersistenceManager

Determine if persistence data is being held for a table.

Specified by:

isPersistenceDataRetained in interface JTablePersistenceManager

Parameters:

name - the name of the table to check against

Returns:

true if the table has persistence data; false otherwise

isPersisting

public boolean isPersisting(JTable table)

Description copied from interface: JTablePersistenceManager

Determine if a table is being persisted.

Specified by:

isPersisting in interface JTablePersistenceManager

Parameters:

table - the table to check against

Returns:

true if the table is being persisted; false otherwise

isPersisting

public boolean isPersisting(String name)

Description copied from interface: JTablePersistenceManager

Determine if a table is being persisted by name.

Specified by:

isPersisting in interface JTablePersistenceManager

Parameters:

name - the name of the table to check against

Returns:

true if the table is being persisted; false otherwise

propertyChange

public void propertyChange(PropertyChangeEvent evt)

Specified by:

propertyChange in interface PropertyChangeListener
