Detailed Description

A container for handling SCH_SHEET_PATH objects in a flattened hierarchy.

SCH_SHEET objects are not unique, there can be many sheets with the same filename and that share the same SCH_SCREEN reference. Each The schematic file (SCH_SCREEN) may be shared between these sheets and symbol references are specific to a sheet path. When a sheet is entered, symbol references and sheet page number are updated.

SCH_SHEET_LIST()

SCH_SHEET_LIST::SCH_SHEET_LIST	(	SCH_SHEET *	aSheet = nullptr,
		bool	aCheckIntegrity = false
	)

Construct a flattened list of SCH_SHEET_PATH objects from aSheet.

If aSheet == NULL, then this is an empty hierarchy which the user can populate.

AllSheetPageNumbersEmpty()

bool SCH_SHEET_LIST::AllSheetPageNumbersEmpty

)

const

Check all of the sheet instance for empty page numbers.

Note

Returns

true if all sheet instance page numbers are not defined. Otherwise false.

AnnotatePowerSymbols()

void SCH_SHEET_LIST::AnnotatePowerSymbols

(

)

Silently annotate the not yet annotated power symbols of the entire hierarchy of the sheet path list.

It is called before creating a netlist, to annotate power symbols, without prompting the user about not annotated or duplicate for these symbols, if only these symbols need annotation ( a very frequent case ).

BuildSheetList()

void SCH_SHEET_LIST::BuildSheetList	(	SCH_SHEET *	aSheet,
		bool	aCheckIntegrity
	)

Build the list of sheets and their sheet path from aSheet.

If aSheet is the root sheet, the full sheet path and sheet list are built.

The list will be ordered as per SCH_SCREEN::GetSheets which results in sheets being ordered in the legacy way of using the X and Y positions of the sheets.

SortByPageNumbers to sort by page numbers

Parameters

aSheet

is the starting sheet from which the list is built, or NULL indicating that g_RootSheet should be used.

Exceptions

std::bad_alloc

if the memory for the sheet path list could not be allocated.

SortByPageNumbers()

void SCH_SHEET_LIST::SortByPageNumbers

(

bool

Sort the list of sheets by page number.

This should be called after BuildSheetList

If page numbers happen to be equal, then it compares the sheet names to ensure deterministic ordering.

Parameters

aUpdateVirtualPageNums

If true, updates the virtual page numbers to match the new ordering

Enforce strict ordering. If the page numbers are the same, use UUIDs

TestForRecursion()

bool SCH_SHEET_LIST::TestForRecursion	(	const SCH_SHEET_LIST &	aSrcSheetHierarchy,

	)

Test every SCH_SHEET_PATH in this SCH_SHEET_LIST to verify if adding the sheets stored in aSrcSheetHierarchy to the sheet stored in aDestFileName will cause recursion.

Parameters

aSrcSheetHierarchy	is the SCH_SHEET_LIST of the source sheet add to aDestFileName.
aDestFileName	is the file name of the destination sheet for aSrcFileName.

Returns

true if aFileName will cause recursion in the sheet path. Otherwise false.
