Class RequestCache

java.lang.Object

com.atlassian.plugin.webresource.impl.RequestCache

public class RequestCache
extends Object

A place to store the results of operations performed during a single request-response lifecycle. The cache's primary goal is to "freeze" application state as it is interrogated, so that values are evaluated once and thus stable for the duration of the request-response lifecycle. Avoiding potentially expensive operations being run multiple times is a nice bonus. This class expects to be constructed per request. It is not an appropriate way to marshal and unmarshal application state across multiple requests from a client.

v3.3

Method Detail

toResourceKeys

public static List<ResourceKey> toResourceKeys(List<Resource> resources)

getGlobals

public Globals getGlobals()

getCachedResources

public Map<Bundle,LinkedHashMap<String,Resource>> getCachedResources()

Needed by WebResource as a storage for Cache.

getCachedResources

public List<Resource> getCachedResources(ResourceKeysSupplier resourceKeysSupplier)

Batches and Sub Batches are cached and as such can't contain references to Resources, this cache helps with that.

getCachedConditionsEvaluation

public Map<CachedCondition,Boolean> getCachedConditionsEvaluation()

getCachedConditionsParameters

public Map<CachedCondition,DefaultUrlBuilder> getCachedConditionsParameters()

getSnapshot

public Snapshot getSnapshot()

Get all bundles.

It is another layer of cache over the `globals.getBundles()` because it is used very heavily, to avoid any performance drawbacks of atomic reference in the `globals.getBundles()`.
