Method Detail

addBuildToQueue

public void addBuildToQueue(@NotNull
                            BuildContext buildContext)

Description copied from interface: BuildQueueManager

Attempts to add the build to a queue. A BuildQueuedEvent is fired if queuing was successful and a BuildRejectedFromQueueEvent iif rejected. A lock on the build is obtained from the BuildExecutionManager.

Specified by:

addBuildToQueue in interface BuildQueueManager

Parameters:

buildContext - @NotNull

removeBuildFromQueue

public void removeBuildFromQueue(@NotNull
                                 java.lang.String planKey,
                                 @NotNull
                                 java.lang.String buildResultKey)

Description copied from interface: BuildQueueManager

Removes the BuildContext associated with the buildResultKey to be removed form the queue. A BuildDeQueuedEvent is fired. The lock on the build is not released. The caller should call BuildExecutionManager#finishProcess to release this lock when ready.

Specified by:

removeBuildFromQueue in interface BuildQueueManager

reorderBuildInQueue

public void reorderBuildInQueue(java.lang.String planKey,
                                int index)

Description copied from interface: BuildQueueManager

Reorders the build queue. BuildContext associated with the planKey is moved to new position in the queue indicated by the zero-based index parameter. If index is < 0 or >= size of queue then BuildContext is positioned at the beginning or at the end of the queue respectively.

Specified by:

reorderBuildInQueue in interface BuildQueueManager

Parameters:

planKey - Plan key of the build that shall be repositioned in the queue.

index - New position of a BuildContext associated with the planKey in the queue.

reorderBuildInQueue

public boolean reorderBuildInQueue(@NotNull
                                   java.lang.String buildResultKey,
                                   @Nullable
                                   java.lang.String prevBuildResultKey,
                                   @Nullable
                                   java.lang.String nextBuildResultKey)

Description copied from interface: BuildQueueManager

Moves a given build in a queue in between two given builds. Required because: - By the time a user requests a reorder that plan may already have shifted up the queue (possibly by a considerable number of positions) thus it may be that be reordering to position 3 your may have actually pushed it down the queue rather than up where you wanted it. By reordering between two plans on the queue you basically eliminate this problem. - It allows us to check that the target position of the queue is as the user expects, so we can detect if there was a queue repositioning clash (by another user reordering the queue remotely). You must specify buildResultKey and either prevBuildResultKey or nextBuildResultKey (or both).

Specified by:

reorderBuildInQueue in interface BuildQueueManager

Returns:

true if queue has been successfully reordered and false otherwise (e.g. previous and next builds were not adjacent)

getBuildQueue

@NotNull
public java.util.List<BuildContext> getBuildQueue()

Description copied from interface: BuildQueueManager

Returns a thread safe list of BuildContext objects representing the builds that is in the queue

Specified by:

getBuildQueue in interface BuildQueueManager

Returns:

List of BuildContext. Changes to this List is not reflected in the queue.

queueContains

public boolean queueContains(java.lang.String planKey)

Description copied from interface: BuildQueueManager

Indicates whether a build of a given build plan is in the queue.

Specified by:

queueContains in interface BuildQueueManager

Parameters:

planKey - The build plan key

Returns:

true if a build of the given build plan is in the queue, false otherwise.

reconstructBuildQueue

public void reconstructBuildQueue()

Description copied from interface: BuildQueueManager

Reconstructs the build queue. This needs to happen in the following scenarios: - Agent capability gets updated - Agent enabled/disabled - Plan configuration (requirements) updated.

Specified by:

reconstructBuildQueue in interface BuildQueueManager
