public class DefaultTransitManager
extends AbstractManager<Transit>
implements TransitManager

Implementation of a Transit Manager

This doesn't need an interface, since Transits are globaly implemented, instead of being system-specific.

Note that Transit system names must begin with system prefix and type character, usually IZ, and be followed by a string, usually, but not always, a number. This is enforced when a Transit is created.

Constructor Detail

DefaultTransitManager

public DefaultTransitManager()

Method Detail

addVetoListener

final void addVetoListener()

getXMLOrder

public int getXMLOrder()

Description copied from interface: Manager

Determine the order that types should be written when storing panel files. Uses one of the constants defined in this class.

Yes, that's an overly-centralized methodology, but it works for now.

Specified by:

getXMLOrder in interface Manager<Transit>

Returns:

write order for this Manager; larger is later.

typeLetter

public char typeLetter()

Specified by:

typeLetter in interface Manager<Transit>

Returns:

The type letter for a specific implementation

createNewTransit

@Nonnull
public Transit createNewTransit(@CheckForNull
                                java.lang.String systemName,
                                java.lang.String userName)
                         throws NamedBean.BadNameException

Create a new Transit if the Transit does not exist. This is NOT a provide method.

Specified by:

createNewTransit in interface TransitManager

Parameters:

systemName - the desired system name

userName - the desired user name

Returns:

a new Transit

Throws:

NamedBean.BadNameException - if a Transit with the same systemName or userName already exists, or if there is trouble creating a new Transit.

createNewTransit

@Nonnull
public Transit createNewTransit(java.lang.String userName)
                         throws NamedBean.BadNameException

For use with User GUI, to allow the auto generation of systemNames, where the user can optionally supply a username.

Note: Since system names should be kept short for use in Dispatcher, automatically generated system names are in the form IZnn, where nn is the first available number.

Specified by:

createNewTransit in interface TransitManager

Parameters:

userName - the desired user name

Returns:

a new Transit

Throws:

NamedBean.BadNameException - if userName is already associated with another Transit

getTransit

@CheckForNull
public Transit getTransit(java.lang.String name)

Get an existing Transit. 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.

Specified by:

getTransit in interface TransitManager

Parameters:

name - User name or system name to match

Returns:

null if no match found

deleteTransit

public void deleteTransit(Transit z)

Remove an existing Transit.

Specified by:

deleteTransit in interface TransitManager

Parameters:

z - the transit to remove

getListUsingSection

@Nonnull
public java.util.ArrayList<Transit> getListUsingSection(Section s)

Get a list of Transits which use a specified Section.

Specified by:

getListUsingSection in interface TransitManager

Parameters:

s - the section to check Transits against

Returns:

a list, possibly empty, of Transits using section s.

getListUsingBlock

@Nonnull
public java.util.ArrayList<Transit> getListUsingBlock(Block b)

Specified by:

getListUsingBlock in interface TransitManager

getListEntryBlock

@Nonnull
public java.util.ArrayList<Transit> getListEntryBlock(Block b)

Specified by:

getListEntryBlock in interface TransitManager

getBeanTypeHandled

@Nonnull
public java.lang.String getBeanTypeHandled(boolean plural)

Description copied from interface: Manager

Get the user-readable name of the type of NamedBean handled by this manager.

For instance, in the code where we are dealing with just a bean and a message that needs to be passed to the user or in a log.

Specified by:

getBeanTypeHandled in interface Manager<Transit>

Parameters:

plural - true to return plural form of the type; false to return singular form

Returns:

a string of the bean type that the manager handles, eg Turnout, Sensor etc

getNamedBeanClass

public java.lang.Class<Transit> getNamedBeanClass()

Get the class of NamedBean supported by this Manager. This should be the generic class used in the Manager's class declaration.

Specified by:

getNamedBeanClass in interface Manager<Transit>

Returns:

the class supported by this Manager.

dispose

public void dispose()

Description copied from class: AbstractManager

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<Transit>

Overrides:

dispose in class AbstractManager<Transit>
