The following example illustrates the use of the snapshot journal. The AcisOptions object is created and the name JOURNAL_3D is assigned. The AcisOptions object is passed into every API (remember that this object also contains the version information). The journal is inactive until
api_start_journal is called. The function produces scripts only after the journal is enabled. The journal operation can be paused, resumed or ended.
|
|
|
This example generates
JOURNAL_3D.scm and five SAT files - JOURNAL_3D_0.sat,
JOURNAL_3D_1.sat,
JOURNAL_3D_2.sat,
JOURNAL_3D_3.sat,
JOURNAL_3D_4.sat.
JOURNAL_3D.scm contains the snapshots of five API calls. The options set in the scheme file might vary depending on the state of
ACIS.
