Detailed Description

A base class that BOARD loading and saving plugins should derive from.

Implementations can provide either Load() or Save() functions, or both. PLUGINs throw exceptions, so it is best that you wrap your calls to these functions in a try catch block. Plugins throw exceptions because it is illegal for them to have any user interface calls in them whatsoever, i.e. no windowing or screen printing at all.

The compiler writes the "zero argument" constructor for a PLUGIN automatically if you do not provide one. If you decide you need to provide a zero argument constructor of your own design, that is allowed. It must be public, and it is what the IO_MGR uses. Parameters may be passed into a PLUGIN via the PROPERTIES variable for any of the public API functions which take one.

   try
   {
        IO_MGR::Load(...);
   or
        IO_MGR::Save(...);
   }
   catch( const IO_ERROR& ioe )
   {
        // grab text from ioe, show in error window.
   }

◆ FootprintDelete()

void PLUGIN::FootprintDelete	(	const wxString &	aLibraryPath,
		const wxString &	aFootprintName,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

Delete aFootprintName from the library at aLibraryPath.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several footprints.
aFootprintName	is the name of a footprint to delete from the specified library.
aProperties	is an associative array that can be used to tell the library delete function anything special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR if there is a problem finding the footprint or the library, or deleting it.

Reimplemented in PCB_IO, and GPCB_PLUGIN.

◆ FootprintEnumerate()

void PLUGIN::FootprintEnumerate	(	wxArrayString &	aFootprintNames,
		const wxString &	aLibraryPath,
		bool	aBestEfforts,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

Return a list of footprint names contained within the library at aLibraryPath.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several footprints.
aProperties	is an associative array that can be used to tell the plugin anything needed about how to perform with respect to aLibraryPath. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.
aFootprintNames	is the array of available footprint names inside a library.
aBestEfforts	if true, don't throw on errors, just return an empty list.

Exceptions

IO_ERROR if the library cannot be found, or footprint cannot be loaded.

◆ FootprintExists()

bool PLUGIN::FootprintExists	(	const wxString &	aLibraryPath,

virtual

Check for the existence of a footprint.

◆ FootprintLibCreate()

void PLUGIN::FootprintLibCreate	(	const wxString &	aLibraryPath,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

Create a new empty footprint library at aLibraryPath empty.

It is an error to attempt to create an existing library or to attempt to create on a "read only" location.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several footprints.
aProperties	is an associative array that can be used to tell the library create function anything special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR if there is a problem finding the library, or creating it.

◆ FootprintLibDelete()

bool PLUGIN::FootprintLibDelete	(	const wxString &	aLibraryPath,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

Delete an existing footprint library and returns true, or if library does not exist returns false, or throws an exception if library exists but is read only or cannot be deleted for some other reason.

Parameters

aLibraryPath	is a locator for the "library", usually a directory or file which will contain footprints.
aProperties	is an associative array that can be used to tell the library delete implementation function anything special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Returns: true if library deleted, false if library did not exist.

Exceptions

IO_ERROR if there is a problem deleting an existing library.

◆ FootprintLibOptions()

void PLUGIN::FootprintLibOptions ( PROPERTIES * aListToAppendTo ) const

virtual

Append supported PLUGIN options to aListToAppenTo along with internationalized descriptions.

Options are typically appended so that a derived PLUGIN can call its base class function by the same name first, thus inheriting options declared there. Some base class options could pertain to all Footprint*() functions in all derived PLUGINs.

Note: Since aListToAppendTo is a PROPERTIES object, all options will be unique and last guy wins.

Parameters

aListToAppendTo

holds a tuple of

option: This eventually is what shows up into the fp-lib-table "options" field, possibly combined with others.
internationalized description: The internationalized description is displayed in DIALOG_FP_PLUGIN_OPTIONS. It may be multi-line and be quite explanatory of the option.

In the future perhaps aListToAppendTo evolves to something capable of also holding a wxValidator for the cells in said dialog: http://forums.wxwidgets.org/viewtopic.php?t=23277&p=104180. This would require a 3 column list, and introducing wx GUI knowledge to PLUGIN, which has been avoided to date.

◆ FootprintLoad()

FOOTPRINT * PLUGIN::FootprintLoad	(	const wxString &	aLibraryPath,
		const wxString &	aFootprintName,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

Load a footprint having aFootprintName from the aLibraryPath containing a library format that this PLUGIN knows about.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several footprints.
aFootprintName	is the name of the footprint to load.
aProperties	is an associative array that can be used to tell the loader implementation to do something special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Returns: the FOOTPRINT object if found caller owns it, else NULL if not found.

Exceptions

IO_ERROR if the library cannot be found or read. No exception is thrown in the case where aFootprintName cannot be found.

◆ FootprintSave()

void PLUGIN::FootprintSave	(	const wxString &	aLibraryPath,
		const FOOTPRINT *	aFootprint,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

Write aFootprint to an existing library located at aLibraryPath.

If a footprint by the same name already exists, it is replaced.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several footprints.
aFootprint	is what to store in the library. The caller continues to own the footprint after this call.
aProperties	is an associative array that can be used to tell the saver how to save the footprint, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR if there is a problem saving.

◆ GetLibraryTimestamp()

virtual long long PLUGIN::GetLibraryTimestamp ( const wxString & aLibraryPath ) const

pure virtual

Generate a timestamp representing all the files in the library (including the library directory).

Timestamps should not be considered ordered, they either match or they don't.

Implemented in PCB_IO, EAGLE_PLUGIN, LEGACY_PLUGIN, GPCB_PLUGIN, FABMASTER_PLUGIN, ALTIUM_DESIGNER_PLUGIN, PCAD_PLUGIN, ALTIUM_CIRCUIT_MAKER_PLUGIN, ALTIUM_CIRCUIT_STUDIO_PLUGIN, and CADSTAR_PCB_ARCHIVE_PLUGIN.

◆ IsFootprintLibWritable()

bool PLUGIN::IsFootprintLibWritable ( const wxString & aLibraryPath )

virtual

Return true if the library at aLibraryPath is writable.

The system libraries are typically read only because of where they are installed..

Parameters

aLibraryPath is a locator for the "library", usually a directory, file, or URL containing several footprints.

Exceptions

IO_ERROR if no library at aLibraryPath exists.

◆ Load()

BOARD * PLUGIN::Load	(	const wxString &	aFileName,
		BOARD *	aAppendToMe,
		const PROPERTIES *	aProperties = `nullptr`,
		PROJECT *	aProject = `nullptr`
	)

virtual

Load information from some input file format that this PLUGIN implementation knows about into either a new BOARD or an existing one.

This may be used to load an entire new BOARD, or to augment an existing one if aAppendToMe is not NULL.

Parameters

aFileName	is the name of the file to use as input and may be foreign in nature or native in nature.
aAppendToMe	is an existing BOARD to append to, but if NULL then this means "do not append, rather load anew".
aProperties	is an associative array that can be used to tell the loader how to load the file, because it can take any number of additional named arguments that the plugin is known to support. These are tuning parameters for the import or load. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.
aProject	is the optional PROJECT object primarily used by third party importers.

Returns: the successfully loaded board, or the same one as aAppendToMe if aAppendToMe was not NULL, and caller owns it.

Exceptions

IO_ERROR if there is a problem loading, and its contents should say what went wrong, using line number and character offsets of the input file if possible.

◆ PrefetchLib()

void PLUGIN::PrefetchLib	(	const wxString &	aLibraryPath,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

If possible, prefetches the specified library (e.g.

performing downloads). Does not parse. Threadsafe.

This is a no-op for libraries that cannot be prefetched. Plugins that cannot prefetch need not override this; a default no-op is provided.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several footprints.
aProperties	is an associative array that can be used to tell the plugin anything needed about how to perform with respect to aLibraryPath. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR if there is an error prefetching the library.

◆ Save()

void PLUGIN::Save	(	const wxString &	aFileName,
		BOARD *	aBoard,
		const PROPERTIES *	aProperties = `nullptr`
	)

virtual

Write aBoard to a storage file in a format that this PLUGIN implementation knows about or it can be used to write a portion of aBoard to a special kind of export file.

Parameters

aFileName	is the name of a file to save to on disk.
aBoard	is the class BOARD in memory document tree from which to extract information when writing to aFileName. The caller continues to own the BOARD, and the plugin should refrain from modifying the BOARD if possible.
aProperties	is an associative array that can be used to tell the saver how to save the file, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it) and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR if there is a problem saving or exporting.
