/**
* @class AliHLTTriggerPhosClusterEnergy
* HLT trigger component for high energy clusters in PHOS
*
* Triggers on PHOS clusters containing energy > threshold value.
* Configurable through database entry or from command line using "-energy" option
*
*
General properties:
*
* Component ID: \b PhosClusterEnergyTrigger
* Library: \b libAliHLTTrigger.so
* Input Data Types: kAliHLTDataTypeESDObject, kAliHLTDataTypeESDTree
* Output Data Types: ::kAliHLTAnyDataType
*
* Mandatory arguments:
*
*
* Optional arguments:
*
*
* Configuration:
*
* \li -energy e
* required energy of the cluster
*
* By default, configuration is loaded from OCDB, can be overridden by
* component arguments.
*
* Default CDB entries:
* HLT/ConfigHLT/PhosClusterEnergyTrigger: TObjString storing the arguments
*
* Performance:
*
*
* Memory consumption:
*
*
* Output size:
*
*
* \ingroup alihlt_trigger_components
