public Serializable getKey()
CacheableProcessingComponent
The cache key is the single most important part of the caching implementation. If you don't get it right, you can introduce more load on the caching engine than is necessary. It is important that the cache key has the following attributes:
Thankfully there is a perfectly suitable object that satisfies these
obligations from Java's core: java.lang.String
. You can
also use your own specific key objects provided they respect the above
contracts.
Important:If the cache key is null
then
your component will not be cached at all. You can use this to your
advantage to cache some things but not others.
getKey
in interface CacheableProcessingComponent
null
if the component
is currently not cacheable.public SourceValidity getValidity()
CacheableProcessingComponent
getKey()
method.
The caching contracts use the Excalibur SourceValidity
interface to determine whether a resource is valid or not. The validity
can be a compound check that incorporates time since creation, parameter
values, etc. As long as the sitemap can determine whether the cached
resource is valid or not. More information is available on the
Apache
Excalibur site. Alternatively you can use the built in
CacheValidity
objects in the
org.apache.cocoon.caching
package and then use the
CacheValidityToSourceValidity
adaptor object.
