Module twisted.python.components

Component architecture for Twisted.

Classes
`_NoImplementor`	Same as _Nothing but used by MetaInterface.__call__
`_Nothing`	An alternative to None - default value for functions which raise if default not passed.
`_Wrapper`	Makes any object be able to be dict key.
`Adapter`	I am the default implementation of an Adapter for some interface.
`AdapterRegistry`
`Componentized`	I am a mixin to allow you to be adapted in various ways persistently.
`Interface`	Base class for interfaces.
`MetaInterface`
`ReprableComponentized`

Exceptions
`CannotAdapt`	Can't adapt some object to some Interface.

Function Summary
	`classToInterfaces(k)`
	`getInterfaces(obj, attr)` Return list of all interfaces an object implements, using a particular attribute name.
	`getRegistry(r)`
	`implements(obj, interfaceClass)` Return boolean indicating if obj implements the given interface.
	`superInterfaces(interface)` Given an interface, return list of super-interfaces (including itself).
	`tupleTreeToList(t, l)` Convert an instance, or tree of tuples, into list.

Function Details

getInterfaces(obj, attr='implements')

Return list of all interfaces an object implements, using a particular attribute name. For example, if you wish to discover what interfaces a class implements directly, pass '__class_implements__' as the attribute name.

implements(obj, interfaceClass)

Return boolean indicating if obj implements the given interface.

superInterfaces(interface)

Given an interface, return list of super-interfaces (including itself).

tupleTreeToList(t, l=None)

Convert an instance, or tree of tuples, into list.

Variable Details

ALLOW_DUPLICATES

Type:: int
Value:: 0

theAdapterRegistry

Type:: AdapterRegistry
Value:: <twisted.python.components.AdapterRegistry instance at 0x81989cc>
