Detailed Description

A sequence variable is a variable whose domain is a set of possible
orderings of the interval variables. It allows ordering of tasks. It
has two sets of methods: ComputePossibleFirstsAndLasts(), which
returns the list of interval variables that can be ranked first or
last; and RankFirst/RankNotFirst/RankLast/RankNotLast, which can be
used to create the search decision.

Member Function Documentation

◆ accept()

void com.google.ortools.constraintsolver.SequenceVar.accept ( ModelVisitor visitor)

Accepts the given visitor.

Definition at line 136 of file SequenceVar.java.

◆ delete()

synchronized void com.google.ortools.constraintsolver.SequenceVar.delete ( )

Reimplemented from com.google.ortools.constraintsolver.PropagationBaseObject.

Definition at line 48 of file SequenceVar.java.

◆ finalize()

void com.google.ortools.constraintsolver.SequenceVar.finalize ( )
protected

Reimplemented from com.google.ortools.constraintsolver.PropagationBaseObject.

Definition at line 44 of file SequenceVar.java.

◆ getCPtr()

static long com.google.ortools.constraintsolver.SequenceVar.getCPtr ( SequenceVar obj)
staticprotected

Definition at line 27 of file SequenceVar.java.

◆ interval()

IntervalVar com.google.ortools.constraintsolver.SequenceVar.interval ( int index)

Returns the index_th interval of the sequence.

Definition at line 113 of file SequenceVar.java.

◆ next()

IntVar com.google.ortools.constraintsolver.SequenceVar.next ( int index)

Returns the next of the index_th interval of the sequence.

Definition at line 121 of file SequenceVar.java.

◆ rankFirst()

void com.google.ortools.constraintsolver.SequenceVar.rankFirst ( int index)

Ranks the index_th interval var first of all unranked interval
vars. After that, it will no longer be considered ranked.

Definition at line 71 of file SequenceVar.java.

◆ rankLast()

void com.google.ortools.constraintsolver.SequenceVar.rankLast ( int index)

Ranks the index_th interval var first of all unranked interval
vars. After that, it will no longer be considered ranked.

Definition at line 87 of file SequenceVar.java.

◆ rankNotFirst()

void com.google.ortools.constraintsolver.SequenceVar.rankNotFirst ( int index)

Indicates that the index_th interval var will not be ranked first
of all currently unranked interval vars.

Definition at line 79 of file SequenceVar.java.

◆ rankNotLast()

void com.google.ortools.constraintsolver.SequenceVar.rankNotLast ( int index)

Indicates that the index_th interval var will not be ranked first
of all currently unranked interval vars.

Definition at line 95 of file SequenceVar.java.

◆ rankSequence()

void com.google.ortools.constraintsolver.SequenceVar.rankSequence ( int[] rank_first,
int[] rank_last,
int[] unperformed )

Applies the following sequence of ranks, ranks first, then rank
last. rank_first and rank_last represents different directions.
rank_first[0] corresponds to the first interval of the sequence.
rank_last[0] corresponds to the last interval of the sequence.
All intervals in the unperformed vector will be marked as such.

Definition at line 106 of file SequenceVar.java.

◆ size()

long com.google.ortools.constraintsolver.SequenceVar.size ( )

Returns the number of interval vars in the sequence.

Definition at line 129 of file SequenceVar.java.

static long com.google.ortools.constraintsolver.SequenceVar.swigRelease ( SequenceVar obj)
staticprotected

Definition at line 31 of file SequenceVar.java.

◆ toString()

String com.google.ortools.constraintsolver.SequenceVar.toString ( )

Reimplemented from com.google.ortools.constraintsolver.PropagationBaseObject.

Definition at line 63 of file SequenceVar.java.
