Interface ConfigureManager

All Known Implementing Classes:

ConfigXmlManager

public interface ConfigureManager

Provide load/store capabilities for general configuration.

Areas of responsibility:

• Register and deregister configuration objects so they can eventually be stored.
• Invoke the load and store operations as needed
• Give access to the configuration objects for independent GUIs

The managed items are divided into four types:

1. "Prefs" - handled first on read, these are the general preferences controlling how the program starts up
2. "Config" - layout configuration information, e.g. turnout, signal, etc
3. "Tool" - (Not really clear yet, but present)
4. "User" - typically information about panels and windows, these are handled last during startup

The configuration manager is generally located through the InstanceManager.

The original implementation was via the jmri.configurexml package.

Method Detail

registerPref

void registerPref(Object o)

removePrefItems

void removePrefItems()

registerConfig

void registerConfig(Object o)

registerTool

void registerTool(Object o)

registerUser

void registerUser(Object o)

deregister

void deregister(Object o)

findInstance

Object findInstance(Class<?> c,
                    int index)

Find the ith instance of an object of particular class that's been registered for storage.

Note that the index of an object can change when other objects are stored or removed. The index is for indexing over the objects stored at a moment, not for use as an identification number.

There may be synchronization issues associated with this, although they are expected to be rare in practice.

Parameters:

c - Class of the desired objects

index - a 1-based index of the object to return

Returns:

an object of class c or null

storeAll

void storeAll(File file)

Stores prefs, config, tools and user information.

Parameters:

file - Output file

storePrefs

void storePrefs(File file)

Stores just preferences information.

Parameters:

file - Output file

storeConfig

void storeConfig(File file)

Stores just configuration information.

Parameters:

file - Output file

storeUser

void storeUser(File file)

Stores just user information.

Parameters:

file - Output file

load

boolean load(File file)

Create the objects defined in a particular configuration file

Parameters:

file - Input file

Returns:

true if succeeded

find

File find(String filename)

Provide a method-specific way of locating a file to be loaded from a name.

Parameters:

filename - Local filename, perhaps without path information

Returns:

Corresponding File object

makeBackup

boolean makeBackup(File file)

Make a backup file.

Parameters:

file - to be backed up

Returns:

true if successful
