public class SubSequence
extends AbstractCPConstraint

Links two CPSeqVar, ensuring a subsequence appears within a super sequence

Constructor Summary

Constructors

Constructor	Description
SubSequence(CPSeqVar mainSequence, CPSeqVar subSequence)	Ensures that the ordering from a subsequence appears within a super sequence, including all of its nodes The super sequence can have other nodes belonging to its ordering as well Example: mainSequence: 0 -> 1 -> 2 -> 3 -> 4 subSequence: 0 -> 2 -> 4

Method Summary

Modifier and Type	Method	Description
void	post()	Initializes the constraint when it is posted to the solver.
void	propagate()	Propagates the constraint.

SubSequence

public SubSequence(CPSeqVar mainSequence,
 CPSeqVar subSequence)

Ensures that the ordering from a subsequence appears within a super sequence, including all of its nodes The super sequence can have other nodes belonging to its ordering as well Example: mainSequence: 0 -> 1 -> 2 -> 3 -> 4 subSequence: 0 -> 2 -> 4

Parameters:

mainSequence - super sequence

subSequence - sub sequence, whose ordering appears within the main sequence. The ordering appearing in the super sequence must not be consecutive
