ObjectSupport
This module contains classes that provide generic functionality for objects: Organizing objects in hierarchies and reflection of objects.
An instance MasterO
of class Object.master
becomes a master of an Object.slave
object when the latter receives the message becomeSlave(
MasterO
)
.
Methods for Masters
init
init()
initialization; mandatory for internal reasons.
getSlaves
getSlaves(
?SlaveOs
)
returns the list of current slaves.
An instance of Object.slave
becomes a slave of an Object.master
object MasterO
when it receives the message becomeSlave(
MasterO
)
.
Methods for Slaves
becomeSlave
becomeSlave(
+MasterO
)
makes self
become a slave of MasterO
. self
must not yet be a slave of any object, else an exception is raised.
isFree
isFree(
?B
)
tests whether self
is not the slave of any object.
free
free()
frees self
. self
must be the slave of some object, else an exception is raised.
The unsited class ObjectSupport.reflect
provides the following methods:
clone
clone(
+O
)
returns a clone of self
(that is, features and current attribute values are equal).
toChunk
toChunk(
?Ch
)
returns a chunk that contains information on current attribute values and features.
fromChunk
fromChunk(
+Ch
)
Sets features and attributes according to chunk Ch
. Ch
must have been created with toChunk
. The current object must have the same class as that from which the chunk was computed.
