note description: "[ Objects that allow dockable sources to be inserted as part of the dockable mechanism. Use `enable_docking` to permit sources to be dropped, and `veto_dock_function` to restrict which sources will be accepted. If a source is rejected by the veto function, then the parent structure will be explored until there are no more parents, or the source being transported is accepted. `docked_actions` is fired after the source of transport has been parented in Current. ]" legal: "See notice at end of class." status: "See notice at end of class." date: "$Date: 2016-09-27 07:50:48 -0800 (Tue, 27 Sep 2016) $" revision: "$Revision: 99192 $" deferred class interface EV_DOCKABLE_TARGET feature -- Access data: detachable ANY -- Arbitrary user data may be stored here. -- (from EV_ANY) generating_type: TYPE [detachable EV_DOCKABLE_TARGET] -- Type of current object -- (type of which it is a direct instance) -- (from ANY) ensure -- from ANY generating_type_not_void: Result /= Void generator: STRING_8 -- Name of current object's generating class -- (base class of the type of which it is a direct instance) -- (from ANY) ensure -- from ANY generator_not_void: Result /= Void generator_not_empty: not Result.is_empty frozen id_object (an_id: INTEGER_32): detachable IDENTIFIED -- Object associated with an_id (void if no such object) -- (from IDENTIFIED) ensure -- from IDENTIFIED consistent: Result = Void or else Result.object_id = an_id is_docking_enabled: BOOLEAN -- May Current be docked to?
