Class ChangesCalculatorDagVisitor

java.lang.Object

jetbrains.buildServer.util.graph.BFSVisitorAdapter<Long>

jetbrains.buildServer.serverSide.impl.ChangesCalculatorDagVisitor

All Implemented Interfaces:

BFSVisitor<Long>

public class ChangesCalculatorDagVisitor
extends BFSVisitorAdapter<Long>

Iterates through DAG until reaches modifications for which there is a promotion, i.e. FindPromotionStrategy.forModification(modification) returns not null. When iteration is over, all visited modifications can be retrieved via getVisitedModifications(). Visitor notify PreviousPromotionsCallback specified in constructor about previous promotions which limit modifications.

Method Detail

setDag

public void setDag(@NotNull
                   DAG<Long> dag)

getVisitedModifications

@NotNull
public List<SVcsModification> getVisitedModifications()

exclude

public void exclude(@NotNull
                    DefaultBranchChangesMode mode,
                    long modId,
                    @NotNull
                    Set<Long> starts)

Excludes all commits reachable from the modification with specified modId according to the specified mode. Should be called after dag is set.

Parameters:

modId - modification id

starts - nodes from which traversal will start

returnModificationsNotAttachedToBuildType

public void returnModificationsNotAttachedToBuildType()

Makes visitor return all visited modifications, even those which are not attached to the buildType specified in the constructor. By default visitor returns only modifications attached to buildType specified in the constructor. Include all modifications is useful when calculate changes from overriden roots, since the are not attached to buildType.

discover

public boolean discover(@NotNull
                        Long modId)

Description copied from interface: BFSVisitor

Called when the node first discovered

Specified by:

discover in interface BFSVisitor<Long>

Overrides:

discover in class BFSVisitorAdapter<Long>

Parameters:

modId - discovered node

Returns:

true if node's parents should be visited, false otherwise

findChangeById

protected SVcsModification findChangeById(@NotNull
                                          Long modId)

searchFinished

public void searchFinished()

Description copied from interface: BFSVisitor

Called when search is finished

Specified by:

searchFinished in interface BFSVisitor<Long>

Overrides:

searchFinished in class BFSVisitorAdapter<Long>

isAttachedToBuildType

protected boolean isAttachedToBuildType(@NotNull
                                        SVcsModification m)

containsNode

public boolean containsNode(long modId)
