Interface ImmutablePlanCacheService

All Known Implementing Classes:

ImmutablePlanCacheServiceImpl

public interface ImmutablePlanCacheService

An experimental API for getting immutable, weakly held, cached ImmutableChain. This Service does not check for permissions currently. Only works for Chain. Cache is disabled by default and should be explicitly enabled by application (preferably by calling initialiseCache())
Concepts:

cache invalidation

Temporary removal of plan from cache (ie as an effect of changed plan configuration). Cache invalidation will remove Plan from cache but will not remove metadata information (ie planKey->id mapping)

cache reset

Permament removal of plan from cache (ie as an effect of plan deletion or move to another project). Cache reset will remove Plan and all related data from the cache.

This class is for internal use only, you should probably be using CachedPlanManager instead. In 3.4, only used for Dashboard Cache

Since:

v3.4

Method Summary

void	cascadeInvalidate(long planId) Removes the cached reference for the passed plan and its children.
void	cascadeInvalidate(PlanKey planKey) Removes the cached reference for the passed plan and its children.
void	disableCache() Disable cache.
void	enableCache() Enable cache.
BambooCacheStats	getCacheStats()
ImmutableChain	getImmutablePlanByKey(PlanKey planKey) Returns a plan if one exists with the key.
ImmutableJob	getMasterOfJob(PlanKey jobKey, PlanKey masterChainKey)
PlanIdentifier	getPlanIdentifierForPermissionCheckingByKey(PlanKey planKey) Returns a Plan skeleton skeleton providing ONLY id and key, that matches the given key This method should be used only for permission checking using Acegi If Job key is provided as a parameter, parent Chain will be returned anyway, as Acegi assertions are defined only for TopLevelPlans

Method Detail

getImmutablePlanByKey

@Nullable
ImmutableChain getImmutablePlanByKey(@NotNull
                                              PlanKey planKey)

Returns a plan if one exists with the key.

Parameters:

planKey -

Returns:

getMasterOfJob

@Nullable
ImmutableJob getMasterOfJob(@NotNull
                                     PlanKey jobKey,
                                     @NotNull
                                     PlanKey masterChainKey)

getPlans

@NotNull
<T extends ImmutablePlan> java.util.List<T> getPlans(java.lang.Class<T> planType)

Returns all Plan's filtered by Class. Does not include plans marked for deletion. This method will not load anything from DB - it will operate only on cached data.

Parameters:

planType - - the type of the plan to retrieve

Returns:

plans sorted by DescriptionProvider.getName()

getPlans

@NotNull
<T extends ImmutablePlan> java.util.List<T> getPlans(java.lang.Class<T> planType,
                                                             @NotNull
                                                             com.google.common.base.Predicate<? super T> filter)

Returns all Plan's filtered by Class. Does not include plans marked for deletion. This method will not load anything from DB - it will operate only on cached data.

Parameters:

planType - - the type of the plan to retrieve

Returns:

plans sorted by DescriptionProvider.getName()

getPlanIdentifierForPermissionCheckingByKey

@Nullable
PlanIdentifier getPlanIdentifierForPermissionCheckingByKey(@NotNull
                                                                    PlanKey planKey)

Returns a Plan skeleton skeleton providing ONLY id and key, that matches the given key This method should be used only for permission checking using Acegi

If Job key is provided as a parameter, parent Chain will be returned anyway, as Acegi assertions are defined only for TopLevelPlans

Parameters:

planKey - of the plan to find

Returns:

plan by the id if found, otherwise null

invalidate

void invalidate(@NotNull
                PlanKey planKey)

Removes the cached Plan. Retains Plan metadata.

Parameters:

planKey - key of the Plan to be removed from cache

cascadeInvalidate

void cascadeInvalidate(@NotNull
                       PlanKey planKey)

Removes the cached reference for the passed plan and its children. Currently only propagates invalidation from Chain to ChainBranch

Parameters:

planKey - key of the Plan to be removed from cache

cascadeInvalidate

void cascadeInvalidate(long planId)

Removes the cached reference for the passed plan and its children. Currently only propagates invalidation from Chain to ChainBranch

Parameters:

planId -

reset

void reset(@NotNull
           PlanKey planKey)

Removes the cached Plan and its metadata.

Parameters:

planKey - key of the Plan to be removed from cache

resetAll

void resetAll()

Nukes the cache

initialiseCache

void initialiseCache()

Clear the cache and attempt to read all Chains from DB in order to cache them. If cache was disabled it will be enabled by this method.

disableCache

void disableCache()

Disable cache. When cache is disabled all cache requests will be logged with severity WARN until cache will be enabled again. This method will clear cache.

enableCache

void enableCache()

Enable cache. This method will not load anything when it is enabled, you should consider calling initialiseCache() instead if you expect plans to be loaded.

getCacheStats

BambooCacheStats getCacheStats()
