Member Function Documentation

void GPCB_PLUGIN::FootprintDelete ( const wxString &  aLibraryPath,
const wxString &  aFootprintName,
const PROPERTIES aProperties = NULL 
)
overridevirtual

Function FootprintDelete deletes aFootprintName from the library at aLibraryPath.

Parameters
aLibraryPathis a locator for the "library", usually a directory, file, or URL containing several footprints.
aFootprintNameis the name of a footprint to delete from the specified library.
aPropertiesis 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_ERRORif there is a problem finding the footprint or the library, or deleting it.

Parameters

aPropertiesis 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.

Function FootprintLibDelete deletes 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
aLibraryPathis a locator for the "library", usually a directory or file which will contain footprints.
aPropertiesis 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.

void PLUGIN::FootprintLibOptions ( PROPERTIES aListToAppendTo) const
virtualinherited

Function FootprintLibOptions appends 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 that since aListToAppendTo is a PROPERTIES object, all options will be unique and last guy wins.

Parameters
aListToAppendToholds 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.

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

Parameters
aLibraryPathis a locator for the "library", usually a directory, file, or URL containing several footprints.
aFootprintNameis the name of the footprint to load.
aPropertiesis 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
MODULE* - if found caller owns it, else NULL if not found.
Exceptions
IO_ERRORif the library cannot be found or read. No exception is thrown in the case where aFootprintName cannot be found.

Function FootprintSave will write aModule to an existing library located at aLibraryPath.

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

Parameters
aLibraryPathis a locator for the "library", usually a directory, file, or URL containing several footprints.
aFootprintis what to store in the library. The caller continues to own the footprint after this call.
aPropertiesis 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_ERRORif there is a problem saving.

bool GPCB_PLUGIN::IsFootprintLibWritable ( const wxString &  aLibraryPath)
overridevirtual

Function IsFootprintLibWritable returns true iff the library at aLibraryPath is writable.

(Often system libraries are read only because of where they are installed.)

Parameters
aLibraryPathis a locator for the "library", usually a directory, file, or URL containing several footprints.
Exceptions
IO_ERRORif no library at aLibraryPath exists.

Reimplemented from PLUGIN.

BOARD * PLUGIN::Load ( const wxString &  aFileName,

virtualinherited

Function Load loads 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
aFileNameis the name of the file to use as input and may be foreign in nature or native in nature.
aAppendToMeis an existing BOARD to append to, but if NULL then this means "do not append, rather load anew".
aPropertiesis 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.
Returns
BOARD* - the successfully loaded board, or the same one as aAppendToMe if aAppendToMe was not NULL, and caller owns it.
Exceptions
IO_ERRORif 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.

void PLUGIN::PrefetchLib ( const wxString &  aLibraryPath,
const PROPERTIES aProperties = NULL

virtualinherited

Function PrefetchLib 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
aLibraryPathis a locator for the "library", usually a directory, file, or URL containing several footprints.
aPropertiesis 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_ERRORif there is an error prefetching the library.

void PLUGIN::Save ( const wxString &  aFileName,

Function Save will 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
aFileNameis the name of a file to save to on disk.
aBoardis 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.
aPropertiesis 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_ERRORif there is a problem saving or exporting.
