All Known Implementing Classes:

SequenceGroupImpl

public interface SequenceGroup
extends DynamicGroup

A group that sets a sequence of values as sensors on its member entities

Usage:

 - type: org.apache.brooklyn.entity.group.SequenceGroup
   id: entity-sequence
   brooklyn.config:
     entityFilter:
       $brooklyn:object:
         type: com.google.common.base.Predicates
         factoryMethod.name: "and"
         factoryMethod.args:
           - $brooklyn:object:
               type: org.apache.brooklyn.core.entity.EntityPredicates
               factoryMethod.name: "applicationIdEqualTo"
               factoryMethod.args:
                 - $brooklyn:attributeWhenReady("application.id")
           - $brooklyn:object:
               type: org.apache.brooklyn.core.entity.EntityPredicates
               factoryMethod.name: "configEqualTo"
               factoryMethod.args:
                 - "sequence.set"
                 - true
     sequenceStart: 0
     sequenceIncrement: 1
     sequenceFormat: "Entity %04x"
     sequenceValueSensor: $brooklyn:sensor("entity.sequence")
     sequenceStringSensor: $brooklyn:sensor("entity.name")
