portage.dbapi.DummyTree module¶

class portage.dbapi.DummyTree.DummyTree(dbapi)¶

Bases: object

Most internal code only accesses the “dbapi” attribute of the binarytree, portagetree, and vartree classes. DummyTree is useful in cases where alternative dbapi implementations (or wrappers that modify or extend behavior of existing dbapi implementations) are needed, since it allows these implementations to be exposed through an interface which is minimally compatible with the *tree classes.
