io.wcm.caravan.pipeline.cache.CacheStrategies

@ProviderType
public final class CacheStrategies
extends Object

Default implementations of different cache strategies.

Method Summary

Modifier and Type	Method	Description
static CacheStrategy	noCache()	No caching.
static CacheStrategy	nonTransientAndTimeToIdle(int duration, TimeUnit unit)	Invalidate item after a time-to-idle interval: The content is considered immutable, and storage time will be extended to specified value on each get operation on this item, so it is kept in cache as long as it is requested.
static CacheStrategy	temporary(int duration, TimeUnit unit)	Stores items only in the local, non-persistent CacheAdapter for the given maximum duration.
static CacheStrategy	timeToIdle(int duration, TimeUnit unit)	Invalidate item after a time-to-idle interval: The content is considered immutable, and storage time will be extended to specified value on each get operation on this item, so it is kept in cache as long as it is requested
static CacheStrategy	timeToLive(int duration, TimeUnit unit)	Invalidate item after a fixed time-to-live interval, using the same duration as storage time and revalidation-interval

Method Detail

timeToLive

public static CacheStrategy timeToLive(int duration,
                                       TimeUnit unit)

Invalidate item after a fixed time-to-live interval, using the same duration as storage time and revalidation-interval

Parameters:

duration - Time-to-live duration

unit - Time unit

Returns:

Cache strategy

timeToIdle

public static CacheStrategy timeToIdle(int duration,
                                       TimeUnit unit)

Invalidate item after a time-to-idle interval: The content is considered immutable, and storage time will be extended to specified value on each get operation on this item, so it is kept in cache as long as it is requested

Parameters:

duration - Time-to-idle duration

unit - Time unit

Returns:

Cache strategy

nonTransientAndTimeToIdle

public static CacheStrategy nonTransientAndTimeToIdle(int duration,
                                                      TimeUnit unit)

Invalidate item after a time-to-idle interval: The content is considered immutable, and storage time will be extended to specified value on each get operation on this item, so it is kept in cache as long as it is requested. Cache operations should be ignored by transient adapters and passed to the persistent adapters only.

Parameters:

duration - Time-to-idle duration

unit - Time unit

Returns:

Cache strategy

temporary

public static CacheStrategy temporary(int duration,
                                      TimeUnit unit)

Stores items only in the local, non-persistent CacheAdapter for the given maximum duration.

Parameters:

duration - maximum Time-to-live

unit - Time unit

Returns:

Cache strategy

noCache

public static CacheStrategy noCache()

No caching. Can be used to disable caching in a JsonPipeline that already has some Cachepoints set.

Returns:

Cache strategy
