apptools.naming.context module

The base class for all naming contexts.

class apptools.naming.context.Context

Bases: HasTraits

The base class for all naming contexts.

INITIAL_CONTEXT_FACTORY = 'apptools.naming.factory.initial'

OBJECT_FACTORIES = 'apptools.naming.factory.object'

STATE_FACTORIES = 'apptools.naming.factory.state'

bind(name, obj, make_contexts=False)

Binds a name to an object.

If ‘make_contexts’ is True then any missing intermediate contexts are created automatically.

create_subcontext(name)

Creates a sub-context.

destroy_subcontext(name)

Destroys a sub-context.

get_unique_name(prefix)

Returns a name that is unique within the context.

The name returned will start with the specified prefix.

is_context(name)

Returns True if the name is bound to a context.

list_bindings(name='')

Lists the bindings in a context.

list_names(name='')

Lists the names bound in a context.

lookup(name)

Resolves a name relative to this context.

lookup_binding(name)

Looks up the binding for a name relative to this context.

lookup_context(name)

Resolves a name relative to this context.

The name MUST resolve to a context.

rebind(name, obj, make_contexts=False)

Binds an object to a name that may already be bound.

If ‘make_contexts’ is True then any missing intermediate contexts are created automatically.

The object may be a different object but may also be the same object that is already bound to the specified name. The name may or may not be already used. Think of this as a safer version of ‘bind’ since this one will never raise an exception regarding a name being used.

rename(old_name, new_name)

Binds a new name to an object.

search(obj)

Returns a list of namespace names that are bound to obj.

unbind(name)

Unbinds a name.
