Contains various base classes used throughout the ORM.

Defines some key base classes prominent within the internals,
as well as the now-deprecated ORM extension classes.

Other than the deprecated extensions, this module and the
classes within are mostly private, though some attributes
are exposed when inspecting mappings.

Represent a particular class attribute mapped by :class:`.Mapper`.

    The most common occurrences of :class:`.MapperProperty` are the
    mapped :class:`.Column`, which is represented in a mapping as
    an instance of :class:`.ColumnProperty`,
    and a reference to another class produced by :func:`.relationship`,
    represented in the mapping as an instance of
    :class:`.RelationshipProperty`.

        This step is the first of two steps to set up an InstrumentedAttribute,

        The second step is typically the init_class_attribute step,
        called from StrategizedProperty via the post_instrument_class()
        hook.  This step assigns additional state to the InstrumentedAttribute
        (specifically the "impl") which has been determined after the
        MapperProperty has determined what kind of persistence
        management it needs to do (e.g. scalar, object, collection, etc).

ZRS(sU
Defines SQL operators for :class:`.MapperProperty` objects.

    SQLAlchemy allows for operators to
    be redefined at both the Core and ORM level.  :class:`.PropComparator`
    is the base class of operator redefinition for ORM-level operations,
    including those of :class:`.ColumnProperty`,
    :class:`.RelationshipProperty`, and :class:`.CompositeProperty`.

    .. note:: With the advent of Hybrid properties introduced in SQLAlchemy
       0.7, as well as Core-level operator redefinition in
       SQLAlchemy 0.8, the use case for user-defined :class:`.PropComparator`
       instances is extremely rare.  See :ref:`hybrids_toplevel` as well
       as :ref:`types_operators`.

    User-defined subclasses of :class:`.PropComparator` may be created. The
    built-in Python comparison and math operator methods, such as
    :meth:`.operators.ColumnOperators.__eq__`,
    :meth:`.operators.ColumnOperators.__lt__`, and
    :meth:`.operators.ColumnOperators.__add__`, can be overridden to provide
    new operator behavior. The custom :class:`.PropComparator` is passed to
    the :class:`.MapperProperty` instance via the ``comparator_factory``
    argument. In each case,
    the appropriate subclass of :class:`.PropComparator` should be used::

        # definition of custom PropComparator subclasses

        from sqlalchemy.orm.properties import \
                                ColumnProperty,\
                                CompositeProperty,\
                                RelationshipProperty

        class MyColumnComparator(ColumnProperty.Comparator):
            def __eq__(self, other):
                return self.__clause_element__() == other

        class MyRelationshipComparator(RelationshipProperty.Comparator):
            def any(self, expression):
                "define the 'any' operation"
                # ...

        class MyCompositeComparator(CompositeProperty.Comparator):
            def __gt__(self, other):
                "redefine the 'greater than' operation"

                return sql.and_(*[a>b for a, b in
                                  zip(self.__clause_element__().clauses,
                                      other.__composite_values__())])


        # application of custom PropComparator subclasses

        from sqlalchemy.orm import column_property, relationship, composite
        from sqlalchemy import Column, String

        class SomeMappedClass(Base):
            some_column = column_property(Column("some_column", String),
                                comparator_factory=MyColumnComparator)

            some_relationship = relationship(SomeOtherClass,
                                comparator_factory=MyRelationshipComparator)

            some_composite = composite(
                    Column("a", String), Column("b", String),
                    comparator_factory=MyCompositeComparator
                )

    Note that for column-level operator redefinition, it's usually
    simpler to define the operators at the Core level, using the
    :attr:`.TypeEngine.comparator_factory` attribute.  See
    :ref:`types_operators` for more detail.

    .. seealso::

        :class:`.ColumnProperty.Comparator`

        :class:`.RelationshipProperty.Comparator`

        :class:`.CompositeProperty.Comparator`

        :class:`.ColumnOperators`

ZRS(s�A MapperProperty which uses selectable strategies to affect
    loading behavior.

    There is a single strategy selected by default.  Alternate
    strategies can be selected at Query time through the usage of
    ``StrategizedOption`` objects via the Query.options() method.

    The mechanics of StrategizedProperty are used for every Query
    invocation for every mapped attribute participating in that Query,
    to determine first how the attribute will be rendered in SQL
    and secondly how the attribute will retrieve a value from a result
    row and apply it to a mapped object.  The routines here are very
    performance-critical.

        or expired column attributes, however this may change in the future.

        This loader generates SQL for a query only once and attempts to  cache
        it; from that point on, if the SQL has been cached it will no longer
        run the :meth:`.Query.options` method of the :class:`.Query`.   The
        :class:`.MapperOption` object that wishes to participate within a lazy
        load operation therefore needs to tell the baked loader that it either
        needs to forego this caching, or that it needs to include the state of
        the :class:`.MapperOption` itself as part of its cache key, otherwise
        SQL or other query state that has been affected by the
        :class:`.MapperOption` may be cached in place of a query that does not
        include these modifications, or the option may not be invoked at all.

        By default, this method returns the value ``False``, which means
        the :class:`.BakedQuery` generated by the lazy loader will
        not cache the SQL when this :class:`.MapperOption` is present.
        This is the safest option and ensures both that the option is
        invoked every time, and also that the cache isn't filled up with
        an unlimited number of :class:`.Query` objects for an unlimited
        number of :class:`.MapperOption` objects.

        .. versionchanged:: 1.2.8 the default return value of
           :meth:`.MapperOption._generate_cache_key` is False; previously it
           was ``None`` indicating "safe to cache, don't include as part of
           the cache key"

        To enable caching of :class:`.Query` objects within lazy loaders, a
        given :class:`.MapperOption` that returns a cache key must return a key
        that uniquely identifies the complete state of this option, which will
        match any other :class:`.MapperOption` that itself retains the
        identical state.  This includes path options, flags, etc.    It should
        be a state that is repeatable and part of a limited set of possible
        options.

        If the :class:`.MapperOption` does not apply to the given path and
        would not affect query results on such a path, it should return None,
        indicating the :class:`.Query` is safe to cache for this given
        loader path and that this :class:`.MapperOption` need not be
        part of the cache key.

s�Describe the loading behavior of a StrategizedProperty object.

    The ``LoaderStrategy`` interacts with the querying process in three
    ways:

    * it controls the configuration of the ``InstrumentedAttribute``
      placed on a class to handle the behavior of the attribute.  this
      may involve setting up class-level callable functions to fire
      off a select operation when the attribute is first accessed
      (i.e. a lazy load)

    * it processes the ``QueryContext`` at statement construction time,
      where it can modify the SQL statement that is being produced.
      For example, simple column attributes will add their represented
      column to the list of selected columns, a joined eager loader
      may establish join clauses to add to the statement.

    * It produces "row processor" functions at result fetching time.
      These "row processor" functions populate a particular attribute
      on a particular mapped instance.
