Package gavo :: Package grammars :: Module customgrammar

Module customgrammar

A grammar that imports a user-defined module and takes the RowIterator from there.

The module has to define a RowIterator derived from CustomRowIterator. It may define a function makeDataPack receiving the grammar as its argument and returning anything. This anything will then be available as self.grammar.dataPack to the row iterator. Use this for expensive, one-time preparations your row iterator has to perform.

Classes
