 long branches,
 long failures,
 long solutions,
 boolean smart_time_check,
 boolean cumulative)

Method Details

getCPtr

public static long getCPtr(RegularLimit obj)

swigRelease

public static long swigRelease(RegularLimit 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

MakeIdenticalClone

public RegularLimit MakeIdenticalClone()

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

init

public void init()

Description copied from class: SearchLimit

This method is called when the search limit is initialized.

Overrides:

init in class SearchLimit

exitSearch

public void exitSearch()

Description copied from class: SearchMonitor

End of the search.

Overrides:

exitSearch in class SearchMonitor

UpdateLimits

public void UpdateLimits(SWIGTYPE_p_absl__Duration time,
 long branches,
 long failures,
 long solutions)

wall_time

public long wall_time()

branches

public long branches()

failures

public long failures()

solutions

public long solutions()

IsUncheckedSolutionLimitReached

public boolean IsUncheckedSolutionLimitReached()

Description copied from class: SearchMonitor

Returns true if the limit of solutions has been reached including
unchecked solutions.

Overrides:

IsUncheckedSolutionLimitReached in class SearchMonitor

progressPercent

public int progressPercent()

Description copied from class: SearchMonitor

Returns a percentage representing the propress of the search before
reaching limits.

Overrides:

progressPercent in class SearchMonitor

toString

public String toString()

Overrides:

toString 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

accept

public void accept(ModelVisitor visitor)

Description copied from class: SearchMonitor

Accepts the given model visitor.

Overrides:

accept in class SearchMonitor
