Modifier and Type	Method and Description
boolean	checkHopAllowsBoardAlight(State s, FlexPatternHop hop, boolean boarding) Returns true if the given hop can be boarded/alighted.

makeHopNewTo

public TemporaryPartialPatternHop makeHopNewTo(RoutingRequest opt,
                                               State state,
                                               FlexPatternHop hop,
                                               PatternArriveVertex to,
                                               Stop toStop)

Description copied from class: GtfsFlexGraphModifier

Create a new FlexPatternHop with a new "to" location (from the route to a new destination).

Specified by:

makeHopNewTo in class GtfsFlexGraphModifier

Parameters:

opt - Options for the graph search

state - State at which the original FlexPatternHop was found during the graph search

hop - Original pattern hop to modify

to - New "to" location

toStop - Stop for new "to" location

Returns:

new pattern hop

makeHopNewFrom

public TemporaryPartialPatternHop makeHopNewFrom(RoutingRequest opt,
                                                 State state,
                                                 FlexPatternHop hop,
                                                 PatternDepartVertex from,
                                                 Stop fromStop)

Description copied from class: GtfsFlexGraphModifier

Create a new FlexPatternHop with a new "from" location (from a new destination to the route).

Specified by:

makeHopNewFrom in class GtfsFlexGraphModifier

Parameters:

opt - Options for the graph search

state - Options for the graph search

hop - Original pattern hop to modify

from - New "from" location

fromStop - Stop for new "from" location

Returns:

new pattern hop

shortenEnd

public TemporaryPartialPatternHop shortenEnd(RoutingRequest opt,
                                             State state,
                                             TemporaryPartialPatternHop hop,
                                             PatternStopVertex to,
                                             Stop toStop)

Description copied from class: GtfsFlexGraphModifier

From an existing TemporaryPartialPatternHop which has a new "from" location, create a new TemporaryPartialPatternHop with the same "from" location and a new "to" location. The existence of this method implies that searches from the origin should take place prior to searches from the destination.

Specified by:

shortenEnd in class GtfsFlexGraphModifier

Parameters:

opt - Options for the graph search

state - ptions for the graph search

hop - Temporary pattern hop to modify

to - New "to" location

toStop - Stop for new "to" location

Returns:

new pattern hop
