Method Detail

getCacheService

public CacheService getCacheService()

Description copied from interface: CacheTemplate

Returns the underlying cache service used.

Specified by:

getCacheService in interface CacheTemplate

setCacheService

public void setCacheService(CacheService cacheService)

getKey

public Object getKey(Object... keyElements)

Description copied from interface: CacheTemplate

Creates a key from the specified elements

Specified by:

getKey in interface CacheTemplate

Parameters:

keyElements - the key elements

Returns:

the key

getObject

public <T> T getObject(Context context,
                       org.craftercms.commons.lang.Callback<T> callback,
                       Object... keyElements)

Description copied from interface: CacheTemplate

Executes the template, using the specified callback to load the object to cache, if it's not already in the cache. Works like CacheTemplate.getObject(org.craftercms.core.service.Context, org.craftercms.core.service.CachingOptions, org.craftercms.commons.lang.Callback, Object...), but with default caching options.

Specified by:

getObject in interface CacheTemplate

Parameters:

context - the context (needed by the cache service)

callback - the callback to use in case the object is not in the cache

keyElements - the key elements, used to create the final cache key

Returns:

the cached object

getObject

public <T> T getObject(Context context,
                       CachingOptions cachingOptions,
                       org.craftercms.commons.lang.Callback<T> callback,
                       Object... keyElements)

Description copied from interface: CacheTemplate

Executes the template, using the specified callback to load the object to cache, if it's not already in the cache.

Specified by:

getObject in interface CacheTemplate

Parameters:

context - the context (needed by the cache service)

cachingOptions - the options used for caching.

callback - the callback to use in case the object is not in the cache

keyElements - the key elements, used to create the final cache key
