Method Detail

convertErrorToSoftError

protected com.google.common.util.concurrent.ListenableFuture<CacheResult> convertErrorToSoftError(com.google.common.util.concurrent.ListenableFuture<CacheResult> cacheResultListenableFuture,
                                                                                                  RuleKey ruleKey)

Converts a failed ListenableFuture<CacheResult> to a CacheResult error. Then logs all CacheResult of type CacheResultType.ERROR. Returns a ListenableFuture<CacheResult> without an Exception.

Parameters:

cacheResultListenableFuture - ListenableFuture input

ruleKey - rule key associated with that cache result

Returns:

a ListenableFuture that holds a CacheResult without Exception
