public class InitStorageCache
extends AbstractStandalone

Adds a LRU cache in the responsible storage handler (usually the Flow actor).

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: InitStorageCache
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-cache <java.lang.String> (property: cache)
    The name of the LRU cache to initialize.
    default:
 

-size <int> (property: size)
    The size of the LRU cache.
    default: 50
    minimum: 1
