Initialization
- Parameters
conn (
Connection or Engine
) – SQLAlchemy connection or enginetables (
list
) – List of tables to reflect, (local name, table name) pairsschemas (
dict
) – schema -> module mappingsymbols (gensaschema.Symbols) – Symbol table
dbname (
str
) – Optional db identifier. Used for informational purposes. If omitted orNone
, the information just won’t be emitted.types (
callable
) – Extra type loader. If the type reflection fails, because SQLAlchemy cannot resolve it, the type loader will be called with the type name, (bound) metadata and the symbol table. It is responsible for modifying the symbols and imports and the dialect’sischema_names
. If omitted orNone
, the reflector will always fail on unknown types.
- __module__ = 'gensaschema._schema'
- __weakref__
list of weak references to the object (if defined)
