Specified by:

getLocalMap in interface RequestCacheContext

Parameters:

requestCache - the cache for which to locate

Returns:

the local storage corresponding to the given request cache

getLocalMapIfExists

@Nullable
public Map<Object,Object> getLocalMapIfExists(RequestCache<?,?> requestCache)

Description copied from interface: RequestCacheContext

Returns the request-scoped storage for the given request cache, if it exists.

Specified by:

getLocalMapIfExists in interface RequestCacheContext

Parameters:

requestCache - the cache for which to locate

Returns:

the local storage corresponding to the given request cache, if it already exists; otherwise null.

clearAll

public void clearAll()

Description copied from interface: RequestCacheContext

Parameters:

requestCache - the cache for which to clear the current thread's local storage

open

public void open()

Increments the nesting depth for this cache context.

Specified by:

open in interface RequestCacheContext

close

public void close()

Decrements the nesting depth for this cache context, or closes and destroys the current context if the nesting depth was already 0 (meaning that this matches the outermost opening of the context).

Specified by:

close in interface RequestCacheContext

markValueLoading

public void markValueLoading()

Description copied from interface: RequestCacheContext

Mark the success of adding the value to map returned by RequestCacheContext.getLocalMap(RequestCache) or RequestCacheContext.getLocalMapIfExists(RequestCache)

Specified by:

markValueLoading in interface RequestCacheContext
