Inspector examples

These are some examples of Inspectors.

Example 1

import os
import re
from spacepy import pycdf
from dbprocessing import DBlogging
from dbprocessing import inspector
from dbprocessing import Version

class Inspector(inspector.inspector):

    code_name = 'ect_L2_V1.0.0.py'

    def inspect(self, kwargs):
        re1 = r'{product_name}_\d\d\d\d\d\d\d\d.*.cdf$'.format(**kwargs)
        if not re.match(re1, self.basename):
            DBlogging.dblogger.debug("Inspector {0}:  re did not match {1} {2}".format(self.code_name, re1, self.basename))
            return None
     try:
         cdf = pycdf.CDF(self.filename)
     except:
         DBlogging.dblogger.debug("Inspector {0}: error in pycdf.CDF()".format(self.code_name))
         return None # malformed file

     try:
         self.diskfile.params['utc_file_date'] = self.extract_YYYYMMDD().date()
     except:
         return None
     ## get the start time from the file
     min_time = min([v[0] for v in cdf.values() if v.type() in (pycdf.const.CDF_EPOCH.value, pycdf.const.CDF_EPOCH16.value) and v.rv() and len(v) > 0])
     max_time = max([v[-1] for v in cdf.values() if v.type() in (pycdf.const.CDF_EPOCH.value, pycdf.const.CDF_EPOCH16.value) and v.rv() and len(v) > 0])
     self.diskfile.params['utc_start_time'] = min_time
     self.diskfile.params['utc_stop_time']  = max_time
     self.diskfile.params['version'] = inspector.extract_Version(self.basename)
     return "That is not my dog." # anything that is not None is good

Example 2

import datetime
import os
import re

from dbprocessing import DBlogging
from dbprocessing import inspector
from dbprocessing import Version

class Inspector(inspector.inspector):

    code_name = 'ephem_0_insp.py'

    def inspect(self, kwargs):
        re1 = r'.*{product_name}.*'.format(**kwargs)
        if not re.match(re1, self.basename):
            DBlogging.dblogger.debug("Inspector {0}:  re did not match {1} {2}".format(self.code_name, re1, self.basename))
            return None

        try:
            dt = self.extract_YYYYMMDD()
        except:
            return None

        self.diskfile.params['utc_file_date'] = dt.date()

        ## get the start time from the file
        min_time = dt
        max_time = dt + datetime.timedelta(days=1) - datetime.timedelta(microseconds=1)
        self.diskfile.params['utc_start_time'] = min_time
        self.diskfile.params['utc_stop_time']  = max_time

        try:
            self.diskfile.params['version'] = Version.Version(1, 0, 0)
        except:
            return None

        return "That is not my dog." # anything that is not None is good
