Node demonstrating how to read from/write to lists of tables.




Documentation
:::::::::::::

This example node demonstrates how to read from and write to a list of
tables. It forwards tables from the input to the output using the source
method available for tables and other data types. This will forward data
from one file to another, without making needless copies. Instead the data
is linked to the source whenever possible.

To run this node you can connect its input port to e.g. a
:ref:`Random Tables` node.

See :ref:`nodewriting` for more information about writing nodes. See
:ref:`datatypeapis` for more information on how to use the APIs of the
different data types in Sympathy for Data.
