gavo.grammars.rowsetgrammar module

A grammar that takes standard tuples as input and turns them into rows of a table.

class gavo.grammars.rowsetgrammar.RowsetGrammar(parent, **kwargs)

Bases: Grammar

A grammar handling sequences of tuples.

To add semantics to the field, it must know the “schema” of the data. This is defined via the table it is supposed to get the input from.

This grammar probably is only useful for internal purposes.
