Comparator
==========

API Access
----------

This example uses the :mod:`stopeight.legacy`, :mod:`stopeight.tests` module and sample data. Please refer to :doc:`stopeight` and :doc:`sample-data` on how to install them.

This attempts to load all the files with ".sp" extension into parallel implementation of stroke analyzer::

    $ cd /path/to/where/stopeight
    >>> from stopeight.util import parser
    >>> lines = parser.process_directory('path/to/where/extracted/sample/data','.sp',legacy._parse_file,legacy.stroke_parallel)

The :mod:`stopeight.multiprocessing.pooling` makes parallel calls to :mod:`stopeight.comparator`.
Note: The IDLE shell does not support spawning.
Run from a Python shell instead::

    >>> from stopeight.multiprocessing import pooling
    >>> comparator = pooling.MPLine(lines)

.. autoclass:: stopeight.comparator.shapeMatchSubSection.ShapeMatchSubSectionClass

   .. automethod:: stopeight.comparator.shapeMatchSubSection.ShapeMatchSubSectionClass.match

   Note: This includes a check for occurences in reverse order.

It tests every line against the whole dataset and itself::

    >>> for i,line in enumerate(lines):
    >>>     matches = comparator.matchLine(line)
    >>>     print('Line '+str(i)+' matched '+str(len(matches))+' occurences '+str(matches))
