|
|
* Class LIB_TABLE
|
|
* holds LIB_TABLE::ROW records, and can be searched in a very high speed
|
|
* way based on logical library name.
|
|
* <p>
|
|
* This class owns the <b>library table</b>, which is like fstab in concept and maps logical
|
|
* library name to library URI, type, and options. It has the following columns:
|
|
* <ul>
|
|
* <li> Logical Library Name
|
|
* <li> Library Type
|
|
* <li> Library URI. The full URI to the library source, form dependent on Type.
|
|
* <li> Options, used for access, such as password
|
|
* </ul>
|
|
* <p>
|
|
* The Library Type can be one of:
|
|
* <ul>
|
|
* <li> "dir"
|
|
* <li> "schematic" i.e. a parts list from another schematic.
|
|
* <li> "subversion"
|
|
* <li> "http"
|
|
* </ul>
|
|
* <p>
|
|
* For now, the Library URI types needed to support the various types can be one of those
|
|
* shown below, which are typical of each type:
|
|
* <ul>
|
|
* <li> "file://C:/mylibdir"
|
|
* <li> "file://home/user/kicadwork/jtagboard.sch"
|
|
* <li> "svn://kicad.org/partlib/trunk"
|
|
* <li> "http://kicad.org/partlib"
|
|
* </ul>
|
|
* <p>
|
|
* The applicable library table is built up from several additive rows (table fragments),
|
|
* and the final table is a (conceptual) merging of the table fragments. Two
|
|
* anticipated sources of the rows are a personal table, and a schematic resident
|
|
* table. The schematic resident table rows are considered a higher priority in
|
|
* the final dynamically assembled library table. A row in the schematic
|
|
* contribution to the library table takes precedence over the personal table
|
|
* if there is a collision on logical library name, otherwise the rows simply
|
|
* combine without issue to make up the applicable library table.
