SQL::Translator::Parser - describes how to write a parser
Parser modules that get invoked by SQL::Translator need to implement a single
function: parse. This function will be called by the SQL::Translator
instance as $class::parse($tr,
$data_as_string), where $tr is
a SQL::Translator instance. Other than that, the classes are free to define
any helper functions, or use any design pattern internally that make the most
sense.
When the parser has determined what exists, it will communicate
the structure to the producer through the SQL::Translator::Schema object.
This object can be retrieved from the translator (the first argument pass to
parse) by calling the schema method:
my $schema = $tr->schema;
The Schema object has methods for adding tables, fields, indices,
etc. For more information, consult the docs for SQL::Translator::Schema and
its related modules. For examples of how this works, examine the source code
for existing SQL::Translator::Parser::* modules.
