N)exc) inspection)util) expressionPASSIVE_NO_RESULTzSymbol returned by a loader callable or other attribute/history retrieval operation when a value could not be determined, based on loader callable flags. PASSIVE_CLASS_MISMATCHzSymbol indicating that an object is locally present for a given primary key identity but it is not of the requested class. The return value is therefore None and no SQL should be emitted. ATTR_WAS_SETzSymbol returned by a loader callable to indicate the retrieved value, or values, were assigned to their attributes on the target object. ATTR_EMPTYz@Symbol used internally to indicate an attribute had no callable.NO_VALUEzSymbol which may be placed as the 'previous' value of an attribute, indicating no value was loaded for an attribute when it was modified, and flags indicated we were not to load it. NEVER_SETzSymbol which may be placed as the 'previous' value of an attribute indicating that the attribute had not been assigned to previously.

SQL_OKzBLoader callables can emit SQL at least on scalar value attributes.RELATED_OBJECT_OKzZCallables can use SQL to load related objects as well as scalar value attributes. INIT_OKzAttributes should be initialized with a blank value (None or an empty collection) upon get, if no other value can be obtained. NON_PERSISTENT_OKz9Callables can be emitted if the parent is not persistent.LOAD_AGAINST_COMMITTEDzUCallables should use committed values as primary/foreign keys during a load.

The attributes defined here allow the usage of simple boolean checks to test basic facts about the object returned. While the boolean checks here are basically the same as using the Python isinstance() function, the flags here can be used without the need to import all of these classes, and also such that the SQLAlchemy class system can change while leaving the flags here intact for forwards-compatibility. rFN)r5 __module__ __qualname____doc__ __slots__rru is_instancert is_property is_attribute_is_internal_proxyrsr/extension_typerr>r<rrs}  IM(GKHIEKIL  +#N  r>rc2eZdZdZejdZdS)InspectionAttrInfoaAdds the ``.info`` attribute to :class:`.InspectionAttr`.
