File_AT — Test task representing an arbitrary disk file.¶
This module defines the File_AT class.
-
class
admit.at.File_AT.File_AT(**keyval)[source]¶ Hold a file reference.
See also File_AT for the design document.
The resulting File_BDP holds a reference to a file, useful for bootstrapping your flow if you don’t strictly need something complex such as Ingest_AT. Used primarily by the Flow*_AT family for testing.
Other realistic examples, besides Ingest_AT, are BDPIngest_AT and GenerateSpectrum_AT.py.
Keywords
- file: string
- The name of the file. See below for controlling parameters if the file needs to exist or if it can be created. File has to be a file within the admit project, absolute paths are not allowed. No default.
- touch: bool
- If True, the “touch” system command is used on the file, which will then either create a zero length file, or else update the timestamp of an existing file. Probably only useful for testing. Default: False.
- exist: bool
- If True, the input file is checked for existence before it could even be touched. An exception is thrown if the file does not exist and should exist. Default: True.
- Input BDPs
- None
Output BDPs
File_BDP: count: 1Parameters: keyval : dictionary, optional
Keyword-value pairs, directly passed to the contructor for ease of assignment.
Methods
addinput(item[, slot])Add a BDP input to an AT. addinputbdp(item[, slot, insert])Add a BDP to the _bdp_in list. addoutput(item[, slot])Add a BDP output product to an AT. addoutputbdp(item[, slot, insert])Add a BDP to the _bdp_out list. baseDir([path])Get/set project base directory. bestMatch(at1, at2)Determines the better match of two tasks to the current one. checkfiles()Check if the files from all the BDP_out’s in an AT exist. checktype(item)Check the type of an object to see if it is a BDP. clearinput()Clear the input BDP list. clearoutput([delete])Clear the output BDP list. copy()Creates an independent duplicate of the task. delete()Method to delete the AT and underlying BDPs. delinput(slot)Delete a specific BDP in the _bdp_in list. deloutput(slot)Delete a specific BDP in the _bdp_out list. dir([filename])Absolute directory reference of the ADMIT project. dryrun()Method to do a dry run of the AT, generally just checks input values for errors. enabled([state])Returns current task enabled setting, with optional reset. execute([args])Executes the task. freeAlias(aliases[, alias])Deletes alias reservation, if present. get(attrib)Method to get the given attributes value getProject()Retrieves project ID associated with the task. getVersion()Return the version string. getdtd(fl)Method to write out the dtd data. geteffectivelevel()Method to get the effective logging level of the logging subsystem getkey(key)Retrieval value for a key. getloggername()Method to get the name of the logger for this AT instance getlogginglevel()Method to get the current logging level of the AT haskey(key)Query if a key exists for an AT. html(inheader)Method to represent the current AT in HTML format. id([strip])Returns task ID number. isAutoAlias([withEmpty, compat])Whether the task alias appears to be auto-generated. isequal(at)Method to determine if two ATs are the same. isstale()Returns whether the AT is out of date. len2()Returns the length of _bdp_in and _bdp_out in a tuple. link()Increments the task link count. markChanged()Mark an AT that it’s state was changed, so it would need to be rerun. markUpToDate()Resets _stale to indicate that the AT does not need to be run. merge(at[, aliases])Merges attributes from another task. mkdir(dirname)Make a directory in the ADMIT hierarchy. mkext(filename, ext[, alias])Return a new filename with a new extension with optional ADMIT alias. newId(tid)Assigns the task a new ID number. reset(a)Performs an in-place shallow copy. run()running the File_AT task running([state])Returns current task execution flag, with optional reset. save()Save (write) any BDPs connected to this AT. set(item, val)Method to set protected attributes, rather than direct access setAlias(aliases[, alias, auto])Sets and registers the task alias, guaranteed unique among registered aliases. setProject(pid)Adds a project ID to task ID. set_bdp_in([bdpin])Validate the _valid_bdp_in list and digest it into the appropriate attributes. set_bdp_out([bout])Validate the _valid_bdp_out list and digest it into the appropriate attributes. seteffectivelevel(level)Method to set the effective logging level of the logging subsystem setkey([name, value, isinit])Set keyword value. setloggername(name)Method to set the name of the logger for this AT instance setlogginglevel(level)Method to set the logging level show()Return the AT type. statusicons()return some html icons representing the enabled/stale status of this task summary()Returns the summary dictionary from the AT, for merging into the ADMIT Summary object. unlink()Decrements the task link count. userdata()Returns the user dictionary from the AT, for merging into the ADMIT userdata object. validateinput([describe])Method to validate the _bdp_in’s against a dictionary of expected types. validatekeys()Method to error check all input keys. write(node)Method to write the AT to disk.
