hum.... yeah, looks kind of crappy... looked better before submitting.
I'll try again:
class init():
def __init__(self):
... some unrelated stuff here
* earlier, a bunch of tasks have been defined.
* the tasks are defined in a module (we may or may not
know the module)
* the following retrieves the these descriptions from a table
def loadBuildCmd(self, builtins=None):
#Use dictFunctionObject (DFO), to step through tasks
# dictionary object is like your 'storage' but uses xml
# as a starting point (converts/switched back and forth
# depending on what is needed
#1) retrieve required/defined tasks submitted to the DB
rows = self.db(self.db.buildData.id>0).select()
last_row = rows.last()
dfo_main = cPickle.loads(last_row.get('dfo_main'))
# 2) retrieve related data to submitted task (I.e. to
rows = self.db(self.db.cmdObjects.id>0).select()
'''--- * 3) retrieve cmd_Init DFO from cmdObjects table
retrieve all cmds/pyModules specified in build
file ---'''
for row in rows:
'''--- load serialized (pickled) data from data ---'''
cmdInit =
cPickle.loads(row.get('dfo_objCmd'))
'''--- iter through ---'''
if 'Cmd' in cmdInit.keys():
'''---

path
to
the module to be invoked. Pass pyModule to blueCmd
---'''
pyModule =
cmdInit.Cmd.pyModule
try:
self.blueCmd(pyModule,row.name)
except Exception as
errObj:
err = cmdException.cmdPlugin(self.db,row.name)
err.blueCmd(errObj,pyModule,all)

chloe,
rowName,
builtIn_CmdName=None):

components = chloe.split('.')
'''---

attributes

for comp in components[1:]:
miaZoe = getattr(miaZoe,
comp)
'''---

worry about __imported__ class since they inherit

step is done, chuck object and class reference

if caraAnne is not None:
del caraAnne
del miaZoe
