Detailed Description

Wrapper module that evaluates the computational performance of python modules.

Uses cProfile.

Attributes:
  module (basf2.Module): The wrapped module that should be profiled.
    Should be a module written in Python, since the profile interacts
    with the interpreter for the measurements, but cannot look into c++ implementations.

  output_file_name (str, optional): Path to the file where the profiling information
    shall be stored. Defaults to profile.txt.

  profiler (cProfile.Profile): Profiler instance to manage and extract the profiling statistics.

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			module,
			output_file_name = None
	)

Create a new PyProfilingModule wrapped around the given module
   which outputs its results to the output_file_name of given (if not, to profile.txt).

Reimplemented from WrapperModule.
