Attributes


IS_IN_DB.__call__ <type 'instancemethod'> belongs to class <type 'instancemethod'>

IS_IN_DB.__class__ <type 'type'> extends (<type 'object'>,) belongs to class <type 'type'>
type(object) -> the object's type type(name, bases, dict) -> a new type

IS_IN_DB.__delattr__ <type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'>
x.__delattr__('name') <==> del x.name

IS_IN_DB.__dict__ <type 'dictproxy'> belongs to class <type 'dictproxy'>

IS_IN_DB.__doc__ <type 'str'> belongs to class <type 'str'>
str(object='') -> string Return a nice string representation of the object. If the argument is a string, the return value is the same object.

IS_IN_DB.__format__ <type 'method_descriptor'> belongs to class <type 'method_descriptor'>
default object formatter

IS_IN_DB.__getattribute__ <type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'>
x.__getattribute__('name') <==> x.name

IS_IN_DB.__hash__ <type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'>
x.__hash__() <==> hash(x)

IS_IN_DB.__init__ <type 'instancemethod'> belongs to class <type 'instancemethod'>

IS_IN_DB.__module__ <type 'str'> belongs to class <type 'str'>
str(object='') -> string Return a nice string representation of the object. If the argument is a string, the return value is the same object.

IS_IN_DB.__new__ <type 'builtin_function_or_method'> belongs to class <type 'builtin_function_or_method'>
T.__new__(S, ...) -> a new object with type S, a subtype of T

IS_IN_DB.__reduce__ <type 'method_descriptor'> belongs to class <type 'method_descriptor'>
helper for pickle

IS_IN_DB.__reduce_ex__ <type 'method_descriptor'> belongs to class <type 'method_descriptor'>
helper for pickle

IS_IN_DB.__repr__ <type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'>
x.__repr__() <==> repr(x)

IS_IN_DB.__setattr__ <type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'>
x.__setattr__('name', value) <==> x.name = value

IS_IN_DB.__sizeof__ <type 'method_descriptor'> belongs to class <type 'method_descriptor'>
__sizeof__() -> int size of object in memory, in bytes

IS_IN_DB.__str__ <type 'wrapper_descriptor'> belongs to class <type 'wrapper_descriptor'>
x.__str__() <==> str(x)

IS_IN_DB.__subclasshook__ <type 'builtin_function_or_method'> belongs to class <type 'builtin_function_or_method'>
Abstract classes can override this to customize issubclass(). This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

IS_IN_DB.__weakref__ <type 'getset_descriptor'> belongs to class <type 'getset_descriptor'>
list of weak references to the object (if defined)

IS_IN_DB.build_set <type 'instancemethod'> belongs to class <type 'instancemethod'>

IS_IN_DB.formatter <type 'instancemethod'> belongs to class <type 'instancemethod'>
For some validators returns a formatted version (matching the validator) of value. Otherwise just returns the value.

IS_IN_DB.options <type 'instancemethod'> belongs to class <type 'instancemethod'>

IS_IN_DB.set_self_id <type 'instancemethod'> belongs to class <type 'instancemethod'>
