public class DefaultRateThrottlingPolicyHeaplet
extends GenericHeaplet

Creates and initializes a DefaultRateThrottlingPolicy in a heap environment. Configuration options:

 
 {
     "type": "DefaultRateThrottlingPolicy",
     "config": {
         "delegateThrottlingRatePolicy"  : reference or               [REQUIRED - the policy that will define the
                                           inlined declaration                    throttling rate to apply]
         "defaultRate" {                 : reference                  [OPTIONAL - the default rate to apply if
                                                                                  the delegated throttling rate
                                                                                  policy returns no rate to apply]
                "numberOfRequests"             : integer              [REQUIRED - The number of requests allowed
                                                                                  to go through this filter during
                                                                                  the duration window.]
                "duration"                     : duration             [REQUIRED - The time window during which the
                                                                                  incoming requests are counted.]
         }
     }
 }
 
 

Example : it applies a rate of 15 requests / sec if the scripted throttling rate policy returns no rate.

 
 {
     "type": "DefaultRateThrottlingPolicy",
     "config": {
         "delegateThrottlingRatePolicy" : "customThrottlingRatePolicy"
         "defaultRate" : {
             "numberOfRequests" : 15,
             "duration" : "1 sec"
         }
     }
 }

create

public Object create()
              throws HeapException

Description copied from class: GenericHeaplet

Called to request the heaplet create an object. Called by Heaplet.create(Name, JsonValue, Heap) after initializing the protected field members. Implementations should parse configuration but not acquire resources, start threads, or log any initialization messages. These tasks should be performed by the GenericHeaplet.start() method.

Specified by:

create in class GenericHeaplet

Returns:

The created object.

Throws:

HeapException - if an exception occurred during creation of the heap object or any of its dependencies.
