Constructor and Description
TspOrderConstraint(int before, int after) Creates a tsp order constraint.

Method Summary

Modifier and Type	Method and Description
int	getAfter()
int	getBefore()
int[]	getUserDataCategories() Returns the required user data categories.
boolean	isSatisfied(TspAnalysisInfo tspAnalysisInfo) Checks if the constraint is satisfied.
void	reset() This method allows a stateful network constraint object to be reset to its original state and reused by network analysis functions.
void	setAfter(int after)
void	setBefore(int before)
void	setNetworkAnalyst(NetworkAnalyst analyst) This method allows caller to pass the network analyst object to this constraint, so that the constraint can call the analysis functions provided by the network analyst, or access the network explorer associated with the network analyst.

Constructor Detail

TspOrderConstraint

public TspOrderConstraint(int before,
                          int after)

Creates a tsp order constraint.

Parameters:

before - the original index of the tsp point that should be visited earlier

after - the original index of the tsp point that should be visited later

Method Detail

isSatisfied

public boolean isSatisfied(TspAnalysisInfo tspAnalysisInfo)

Description copied from interface: Constraint

Checks if the constraint is satisfied.

Specified by:

isSatisfied in interface Constraint<TspAnalysisInfo>

Parameters:

tspAnalysisInfo - the analysis context

LODAnalysisInfo

getUserDataCategories

public int[] getUserDataCategories()

Description copied from interface: TspConstraint

Returns the required user data categories.

Specified by:

getUserDataCategories in interface TspConstraint

Returns:

reset

public void reset()

Description copied from interface: TspConstraint

This method allows a stateful network constraint object to be reset to its original state and reused by network analysis functions.

Specified by:

reset in interface TspConstraint

setNetworkAnalyst

public void setNetworkAnalyst(NetworkAnalyst analyst)

Description copied from interface: TspConstraint

This method allows caller to pass the network analyst object to this constraint, so that the constraint can call the analysis functions provided by the network analyst, or access the network explorer associated with the network analyst. If network analyst is not needed by the constraint, the link level selector can choose to do nothing with this method.

Specified by:

setNetworkAnalyst in interface TspConstraint

setBefore

public void setBefore(int before)

getBefore
