class idmtools.entities.ianalyzer.IAnalyzer(uid=None, working_dir: Optional[str] = None, parse: bool = True, filenames: Optional[List[str]] = None)

Bases: object

An abstract base class carrying the lowest level analyzer interfaces called by ExperimentManager.

abstract __init__(uid=None, working_dir: Optional[str] = None, parse: bool = True, filenames: Optional[List[str]] = None)

A constructor.

Parameters:

  • uid – The unique id identifying this analyzer.

  • working_dir – A working directory to place files.

  • parse – True to leverage the OutputParser; False to get the raw data in the select_simulation_data().

  • filenames – The files for the analyzer to download.

property filenames

Returns user filenames.

Returns:

filenames

initialize() → NoReturn

Call once after the analyzer has been added to the AnalyzeManager.

Add everything depending on the working directory or unique ID here instead of in __init__.

per_group(items: IItemList) → NoReturn

Call once before running the apply on the items.

Parameters:

items – Objects with attributes of type ItemId. IDs of one or more higher-level hierarchical objects can be obtained from these IDs in order to perform tasks with them.

Returns:

None

filter(item: Union[IWorkflowItem, Simulation]) → bool

Decide whether the analyzer should process a simulation/work item.

Parameters:

item – An IItem to be considered for processing with this analyzer.

Returns:

A Boolean indicating whether simulation/work item should be analyzed by this analyzer.

abstract map(data: Dict[str, Any], item: Union[IWorkflowItem, Simulation]) → Any

In parallel for each simulation/work item, consume raw data from filenames and emit selected data.

Parameters:

  • data – A dictionary associating filename with content for simulation data.

  • item – IItem object that the passed data is associated with.

Returns:

Selected data for the given simulation/work item.

abstract reduce(all_data: Dict[Union[IWorkflowItem, Simulation], Any]) → Any

Combine the map() data for a set of items into an aggregate result.

Parameters:

all_data – A dictionary with entries for the item ID and selected data.

destroy() → NoReturn

Call after the analysis is done.

class idmtools.entities.ianalyzer.BaseAnalyzer(uid=None, working_dir: Optional[str] = None, parse: bool = True, filenames: Optional[List[str]] = None)

Bases: idmtools.entities.ianalyzer.IAnalyzer

BaseAnalyzer to allow using previously used dtk-tools analyzers within idmtools.

__init__(uid=None, working_dir: Optional[str] = None, parse: bool = True, filenames: Optional[List[str]] = None)

Constructor for Base Analyzer.

Parameters:

  • uid – The unique id identifying this analyzer.

  • working_dir – A working directory to place files.

  • parse – True to leverage the OutputParser; False to get the raw data in the select_simulation_data().

  • filenames – The files for the analyzer to download.
