API and Code
============
Below is the API documention for the the Stetl Python code.
Main Entry Points
-----------------
There are several entry points through which Stetl can be called.
The most common is to use the commandline script `bin/stetl`. This command should
be available after doing an install.
In some contexts like integrations
you may want to call Stetl via Python. The entries are then.
.. automodule:: stetl.main
:members:
.. automodule:: stetl.etl
:members:
Core Framework
--------------
The core framework is directly under the directory `src/stetl`.
Below are the main seven classes. Their interrelation is as follows:
One or more :class:`stetl.chain.Chain` objects are built from
a Stetl ETL configuration via the :class:`stetl.factory.Factory` class.
A :class:`stetl.chain.Chain` consists of a set of connected :class:`stetl.component.Component` objects.
A :class:`stetl.component.Component` is either an :class:`stetl.input.Input`, an :class:`stetl.output.Output`
or a :class:`stetl.filter.Filter`. Data and status flows as :class:`stetl.packet.Packet` objects
from an :class:`stetl.input.Input` via zero or more :class:`stetl.filter.Filter` objects to a final :class:`stetl.output.Output`.
As a trivial example: an :class:`stetl.input.Input` could be an XML file, a :class:`stetl.filter.Filter` could represent
an XSLT file and an :class:`stetl.output.Output` a PostGIS database. This is effected by specialized classes in
the subpackages inputs, filters, and outputs.
