Method Summary

Modifier and Type	Method and Description
boolean	atSolution() This method is called when a valid solution is found.
boolean	CheckWithOffset(SWIGTYPE_p_absl__Duration offset) Same as Check() but adds the 'offset' value to the current time when time is considered in the limit.
void	copy(SearchLimit limit) Copy a limit.
void	delete()
protected void	finalize()
static long	getCPtr(ImprovementSearchLimit obj)
void	init() This method is called when the search limit is initialized.
void	install() Registers itself on the solver such that it gets notified of the search and propagation events.
SearchLimit	makeClone() Allocates a clone of the limit.

                              int improvement_rate_solutions_distance)

Method Detail

getCPtr

public static long getCPtr(ImprovementSearchLimit obj)

swigRelease

public static long swigRelease(ImprovementSearchLimit obj)

finalize

protected void finalize()

Overrides:

finalize in class SearchLimit

delete

public void delete()

Overrides:

delete in class SearchLimit

copy

public void copy(SearchLimit limit)

Description copied from class: SearchLimit

Copy a limit. Warning: leads to a direct (no check) downcasting of 'limit'
so one needs to be sure both SearchLimits are of the same type.

Overrides:

copy in class SearchLimit

makeClone

public SearchLimit makeClone()

Description copied from class: SearchLimit

Allocates a clone of the limit.

Overrides:

makeClone in class SearchLimit

CheckWithOffset

public boolean CheckWithOffset(SWIGTYPE_p_absl__Duration offset)

Description copied from class: SearchLimit

Same as Check() but adds the 'offset' value to the current time when time
is considered in the limit.

Overrides:

CheckWithOffset in class SearchLimit

atSolution

public boolean atSolution()

Description copied from class: SearchMonitor

This method is called when a valid solution is found. If the
return value is true, then search will resume after. If the result
is false, then search will stop there.

Overrides:

atSolution in class SearchMonitor

init

public void init()

Description copied from class: SearchLimit

This method is called when the search limit is initialized.

Overrides:

init in class SearchLimit

install

public void install()

Description copied from class: SearchMonitor

Registers itself on the solver such that it gets notified of the search
and propagation events. Override to incrementally install listeners for
specific events.

Overrides:

install in class SearchLimit
