Check that all turnouts are correctly set for travel in the designated Section to the next Section. NOTE: This method requires use of the connectivity stored in a Layout Editor panel. NOTE: This method removes the need to specify the LayoutEditor panel.

Parameters:

s - the section to check

seqNum - sequence number for the section

nextSection - the following section

at - the associated train

prevSection - the prior section

Returns:

list of turnouts and their expected states if affected turnouts are correctly set; null otherwise.

                                                                                       int seqNum,
                                                                                       Section nextSection,
                                                                                       ActiveTrain at,
                                                                                       boolean trustKnownTurnouts,
                                                                                       Section prevSection)

Set all turnouts for travel in the designated Section to the next Section. Checks that all turnouts are correctly set for travel in this Section to the next Section, and sets any turnouts that are not correct. The Section must be FREE to set its turnouts. Testing for FREE only occurs if a command needs to be issued. For a command to be issued to set a turnout, the Block containing that turnout must be unoccupied. NOTE: This method does not wait for turnout feedback--it assumes the turnout will be set correctly if a command is issued. NOTE: This method removes the need to specify the LayoutEditor panel.

Parameters:

s - the section to check

seqNum - sequence number for the section

nextSection - the following section

at - the associated train

trustKnownTurnouts - true to trust known turnouts

prevSection - the prior section

Returns:

list of turnouts and their expected states if affected turnouts are correctly set or commands have been issued to set any that aren't set correctly; null if a needed command could not be issued because the turnout's Block is occupied
