* \brief Root base class for all PixInsight module components.
|
||||
*
|
||||
* In PCL, a \e metaobject is a special class describing in formal terms the
|
||||
* functionality and properties of a \e component in a PixInsight module.
|
||||
*
|
||||
* The %MetaObject class provides basic functionality to implement the existing
|
||||
* hierarchical relationships between a module and all of its components. A
|
||||
* %MetaObject contains a list of %MetaObject instances, which generates a tree
|
||||
* structure based on parent-children container relations. This structural
|
||||
* layout has been used in PCL to automatize communication between the core
|
||||
* PixInsight application, modules, and all module components.
