/** Info about complex hierarchies handling:
|
|
* A hierarchical schematic uses sheets (hierarchical sheets) included in a
|
|
* given sheet. Each sheet corresponds to a schematic drawing handled by a
|
|
* SCH_SCREEN structure. A SCH_SCREEN structure contains drawings, and have
|
|
* a filename to write it's data. Also a SCH_SCREEN display a sheet number
|
|
* and the name of the sheet.
|
|
*
|
|
* In simple (and flat) hierarchies a sheet is linked to a SCH_SCREEN,
|
|
* and a SCH_SCREEN is used by only one hierarchical sheet.
|
|
*
|
|
* In complex hierarchies the same SCH_SCREEN (and its data) is shared between
|
|
* more than one sheet. Therefore subsheets (like subsheets in a SCH_SCREEN
|
|
* shared by many sheets) can be also shared. So the same SCH_SCREEN must
|
|
* handle different components references and parts selection depending on
|
|
* which sheet is currently selected, and how a given subsheet is selected.
|
|
* 2 sheets share the same SCH_SCREEN (the same drawings) if they have the
|
|
* same filename.
|
|
*
|
|
* In KiCad each component and sheet receives (when created) an unique
|
|
* identification called Time Stamp. So each sheet has 2 ids: its time stamp
|
|
* (that cannot change) and its name ( that can be edited and therefore is
|
|
* not reliable for strong identification). KiCad uses Time Stamp ( a unique
|
|
* 32 bit id), to identify sheets in hierarchies.
|
|
* A given sheet in a hierarchy is fully labeled by its path (or sheet path)
|
|
* that is the list of time stamp found to access it through the hierarchy
|
|
* the root sheet is /. All other sheets have a path like /1234ABCD or
|
|
* /4567FEDC/AA2233DD/. This path can be displayed as human readable sheet
|
|
* name like: / or /sheet1/include_sheet/ or /sheet2/include_sheet/
|
|
*
|
|
* So to know for a given SCH_SCREEN (a given schematic drawings) we must:
|
|
* 1) Handle all references possibilities.
|
|
* 2) When acceded by a given selected sheet, display (update) the
|
|
* corresponding references and sheet path
|
|
*
|
|
* The class SCH_SHEET_PATH handles paths used to access a sheet. The class
|
|
* SCH_SHEET_LIST allows to handle the full (or partial) list of sheets and
|
|
* their paths in a complex hierarchy. The class EDA_ScreenList allow to
|
|
* handle the list of SCH_SCREEN. It is useful to clear or save data,
|
|
* but is not suitable to handle the full complex hierarchy possibilities
|
|
* (usable in flat and simple hierarchies).
