Method Summary

Modifier and Type	Method and Description
LongitudinalDirectionality	getDirectionality(G gtuType, boolean tryParentsOfGTUType) Retrieve the allowed driving directions for a GTUType.
Boolean	isCompatible(G gtuType, GTUDirectionality directionality) Test if a GTUType can travel over the infrastructure.

Method Detail

isCompatible

Boolean isCompatible(G gtuType,
                     GTUDirectionality directionality)

Test if a GTUType can travel over the infrastructure.

Parameters:

gtuType - GTUType; the type of the GTU

directionality - GTUDirectionality; the direction of the GTU with respect to the design direction of the infrastructure

Returns:

boolean; true if the GTU can travel over the infrastructure in the given direction; false if the GTU can not travel over the infrastructure in the given direction; null if the decision should be made by calling isCompatible on a higher level in the infrastructure hierarchy

getDirectionality

LongitudinalDirectionality getDirectionality(G gtuType,
                                             boolean tryParentsOfGTUType)

Retrieve the allowed driving directions for a GTUType. If there is no match for the specified GTUType in this infrastructure type, this method will recursively check the parent types of the infrastructure element until either a match is found or the root parental type of the infrastructure is reached. When the latter happens without finding a match, what happens next depends on the value of tryParentsOfGTUType.
If tryParentsOfGTUType is false, the value null is returned. If true; the parent of the GTUType is used and the search is repeated, etc. If none of the parents of the GTUType yields a result, this method returns LongitudinalDirectionality.DIR_NONE.

Parameters:

gtuType - GTUType; type of the GTU

tryParentsOfGTUType - boolean; if true; the parents of the GTUType are tried if no match was found for the given GTUType

Returns:

LongitudinalDirectionality; the driving directions for the GTUType, or LongitudinalDirectionality.DIR_NONE if neither the GTUType or any of its parents specifies a directionality
