Object is the super-class of all classes with structural features in XMF.
Object provides access to slots via the 'get/1' and 'set/2' operations.
Object is the default super-class for a class definition - if you do not specify
a super-class then Object is assumed.

Operations |
| addDaemon(d:Element):Element |
All objects have a collection of daemons. A daemon is an operation that is
invoked whenever a slot of the object is updated. The operation is any
invokable value (either an operation or an object that implements the
'invoke/2' operation. The invocation occurs after the slot has been
updated and is supplied with 3 values as the second argument: the slot
(symbol) that has been updated, the new value and the old value.
|
| addMultiDaemon(d:Element,target:Element):Element |
This operation facilitates the addition of daemons that support synchronisation
of multiple objects.

| daemonNamed(name:Element):Element | No Documentation Specified |
| daemonWithId(id:Element):Element | No Documentation Specified |
| daemonWithIdAndTarget(id:Element,target:Element):Element | No Documentation Specified |
| daemons():Element |
Returns the currently defined daemons for the receiver.
Daemons are fired when the object changes state and when
the objects daemons are active.
|
| daemonsActive():Boolean |
Returns whether or not the daemons of this object will be
fired when an update takes place.
|
| destroyDaemon(d:Daemon):Element | No Documentation Specified |
| fire(slot:Element,newValue:Element,oldValue:Element):Element |
When the slot of an object is updated, its daemons are fired by calling
this operation. The operation is supplied with 3 arguments: the name of
the slot that was changed (a symbol), the new value of the slot and the
old value of the slot.
|
| get(name:String):Element |
Returns the value of the named slot of the receiver.
The name may be a string or a symbol. An exception is
raised if the receiver has no slot with the given name.
|
| getProperty(name:Element):Element | No Documentation Specified |
| getStructuralFeatureNames():Set(String) |
Returns the slot names of the object.
|
| hasDaemonNamed(name:Element):Element | No Documentation Specified |
| hasDaemonWithId(id:Element):Element | No Documentation Specified |
| hasDaemonWithIdAndTarget(id:Element,target:Element):Element | No Documentation Specified |
| hasDaemonWithTarget(target:Element):Element | No Documentation Specified |
| hasProperty(name:Element):Element | No Documentation Specified |
| hasSlot(name:Element):Boolean |
Returns true when the receiver has a slot with the given
name. The name may be a string or a symbol.
|
| hasStructuralFeature(name:String):Boolean | No Documentation Specified |
| hotLoad():Boolean |
Hot loading objects run the hotLoad operation when loaded by
the loader. the default is false for this property.
|
| hotLoaded():Object |
This operation is run when the value loader loads an object
that is tagged as being hot loading. By default this operation
does nothing. Specialize this in sub-classes to perform
actions when an object is loaded.
|
| init(args:Element):Element |
When an object is initialised, by default we look for a constructor
that has the same arity as the supplied arguments. If we find one
then it is invoked. Note that we always invoke the 'init/0' operation
after slot initialisation.
|
| initSlots():Element |
Attributes have a slot 'init' that contains an operation or null.
If the value is an operation then invoking the operation with an
object as the target will return an initial value for that slot
of the object.
|
| machineInit(args:Element):Element |
Called when the machine has detected initialization values defined
for one or more attributes. The machine relies on this operation to
perform the slot initialization and then call the init/1 operation.
|
| removeDaemon(d:Element,target:Element):Element |
Removes the supplied daemon.
|
| removeDaemonNamed(name:Element):Element | No Documentation Specified |
| removeDaemonsWithId(id:Element,destroy:Element):Element | No Documentation Specified |
| removeDaemonsWithTarget(target:Element,destroy:Element):Element | No Documentation Specified |
| removeStructuralFeature(name:String):Object | No Documentation Specified |
| renameSlot(oldName:String,newName:String):Element | No Documentation Specified |
| set(name:String,value:Element):Element |
Sets the named slot to the supplied value in the receiver.
Raises an exception if the receiver has no slot with the
supplied name. The name may be a symbol or a string.
|
| setDaemons(daemons:Element):Element | No Documentation Specified |
| setDaemonsActive(active:Boolean):Object |
Sets whether or not the daemons of this receiver will be
fired when an update takes place.
|
| setHotLoad(hotLoad:Boolean):Object |
Sets the hot load status of the receiver.
|
| setProperty(name:Element,value:Element):Element | No Documentation Specified |
| slotMissing(slot:Symbol,value:Element):Element |
Called when an we update the slot of an object and the
slot does not exist.
|
| slotMissing(slot:Symbol):Element |
Called when an we request the slot of an object and the
slot does not exist.
