Member Function Documentation

barn()

def barn (   self )

inherited

Coroutine that receives the dictionaries of names and values from peel and store them.

Reimplemented in PickleHarvestingModule.

Definition at line 289 of file harvesting.py.

create_crop_part_collection()

def create_crop_part_collection ( )

staticinherited

Create the storing objects for the crop values

Currently a numpy.array of doubles is used to store all values in memory.

Definition at line 281 of file harvesting.py.

event()

def event (   self )

inherited

Event method of the module

* Does invoke the prepare method before the iteration starts.
* In each event fetch the StoreArray / iterable StoreObjPtr,
* Iterate through all instances
* Feed each instance to the pick method to deside it the instance is relevant
* Forward it to the peel method that should generated a dictionary of values
* Store each dictionary of values

Definition at line 241 of file harvesting.py.

gather()

def gather (   self )

inherited

Iterator that yield the instances form the StoreArray / iterable StoreObj.

Yields
------
Object instances from the StoreArray, iterable StoreObj or the StoreObj itself
in case it is not iterable.

Definition at line 334 of file harvesting.py.

id()

def id (   self )

inherited

Working around that name() is a method.

Exposing the name as a property using a different name

Definition at line 226 of file harvesting.py.

initialize()

def initialize (   self )

inherited

Initialisation method of the module.

Prepares the receiver stash of objects to be harvestered.

Definition at line 233 of file harvesting.py.

iter_store_obj()

def iter_store_obj (   store_obj )

staticinherited

Obtain a iterator from a StoreObj

Repeatly calls iter(store_obj) or store_obj.__iter__()
until the final iterator returns itself

Returns
-------
iterator of the StoreObj

Definition at line 452 of file harvesting.py.

peel()

def peel	(		self,
			legendre_track_cand
	)

Aggregate the track and MC information for track-fit validation

Reimplemented from HarvestingModule.

Definition at line 54 of file fitValidation.py.

pick()

def pick (   self,   crop  )

inherited

Indicate whether the instance should be forwarded to the peeling

Returns
-------
bool : Indicator if the instance is valueable in the current harverst.

Reimplemented in VxdCdcMergerHarvester, MCParticleHarvester, and VxdCdcMergerHarvesterMCSide.

Definition at line 398 of file harvesting.py.

prepare()

def prepare

(

self

)

 Initialize the harvester

Reimplemented from HarvestingModule.

Definition at line 48 of file fitValidation.py.

refine()

def refine (   self,   crops  )

inherited

Receive the gathered crops and forward them to the refiners.

Reimplemented in PickleHarvestingModule.

Definition at line 407 of file harvesting.py.

terminate()

def terminate (   self )

inherited

Termination method of the module.

Finalize the collected crops.
Start the refinement.

Definition at line 265 of file harvesting.py.
