Class SectionManager

java.lang.Object
  jmri.implementation.AbstractManager
      jmri.SectionManager

All Implemented Interfaces:

PropertyChangeListener, EventListener, Manager

public class SectionManager
extends AbstractManager
implements PropertyChangeListener

Basic Implementation of a SectionManager.

This doesn't have a "new" interface, since Sections are independently implemented, instead of being system-specific.

Note that Section system names must begin with IY, and be followed by a string, usually, but not always, a number. All alphabetic characters in a Section system name must be upper case. This is enforced when a Section is created.

Method Detail

systemLetter

public char systemLetter()

Specified by:

systemLetter in interface Manager

Returns:

The system-specific prefix letter for a specific implementation

typeLetter

public char typeLetter()

Specified by:

typeLetter in interface Manager

Returns:

The type letter for a specific implementation

createNewSection

public Section createNewSection(String systemName,
                                String userName)

Method to create a new Section if the Section does not exist Returns null if a Section with the same systemName or userName already exists, or if there is trouble creating a new Section.

deleteSection

public void deleteSection(Section y)

Remove an existing Section

getSection

public Section getSection(String name)

Method to get an existing Section. First looks up assuming that name is a User Name. If this fails looks up assuming that name is a System Name. If both fail, returns null.

getBySystemName

public Section getBySystemName(String name)

getByUserName

public Section getByUserName(String key)

validateAllSections

public int validateAllSections(JmriJFrame frame,
                               LayoutEditor lePanel)

Validates all Sections

setupDirectionSensors

public int setupDirectionSensors(LayoutEditor lePanel)

Checks direction sensors in SSL for signals. Returns '0' for no errors Returns n, where n is a positive number for number of errors or warnings Returns -1 if there is no LayoutEditor panel Returns -2 if there are no Sections defined

removeDirectionSensorsFromSSL

public int removeDirectionSensorsFromSSL(LayoutEditor lePanel)

Removes direction sensors from SSL for all signals. Returns '0' for no errors Returns n, where n is a positive number for number of errors or warnings Returns -1 if there is no LayoutEditor panel Returns -2 if there are no Sections defined

instance
