#{<7B>g<EFBFBD> <00> <00>X <00> d Z ddlmZ ddlmZ ej e<05> Zdd<04>Zd<05> Zd<06> Z y) a The inspection module provides the :func:`.inspect` function,
|
|||
|
|
which delivers runtime information about a wide variety
|
|||
|
|
of SQLAlchemy objects, both within the Core as well as the
|
|||
|
|
ORM.
|
|||
|
|
|
|||
|
|
The :func:`.inspect` function is the entry point to SQLAlchemy's
|
|||
|
|
public API for viewing the configuration and construction
|
|||
|
|
of in-memory objects. Depending on the type of object
|
|||
|
|
passed to :func:`.inspect`, the return value will either be
|
|||
|
|
a related object which provides a known interface, or in many
|
|||
|
|
cases it will return the object itself.
|
|||
|
|
|
|||
|
|
The rationale for :func:`.inspect` is twofold. One is that
|
|||
|
|
it replaces the need to be aware of a large variety of "information
|
|||
|
|
getting" functions in SQLAlchemy, such as :meth:`.Inspector.from_engine`,
|
|||
|
|
:func:`.orm.attributes.instance_state`, :func:`.orm.class_mapper`,
|
|||
|
|
and others. The other is that the return value of :func:`.inspect`
|
|||
|
|
is guaranteed to obey a documented API, thus allowing third party
|
|||
|
|
tools which build on top of SQLAlchemy configurations to be constructed
|
|||
|
|
in a forwards-compatible way.

The returned value in some cases may be the

|
|
same object as the one given, such as if a
|
|||
|
|
:class:`.Mapper` object is passed. In other
|
|||
|
|
cases, it will be an instance of the registered
|
|||
|
|
inspection type for the given object, such as
|
|||
|
|
if an :class:`.engine.Engine` is passed, an
|
|||
|
|
:class:`.Inspector` object is returned.
