To support multiple applications with the same AtcgGeneratorSchema schema, some options are passed in using app.atcgGetControlOptions method in the AtcgTestCodeSchema schema. This includes:
Generated schema name
Generated superschema name
Generated superclass name
Name of the logMessage method of the driver schema
List of schemas to be tracked
List of noise methods to exclude from method tracking
The global.atcgMyControl method in the GAtcgGeneratorSchema class can be accessed from the atcgGetControlOptions method, so you can actually set other options that are not provided for with explicit parameters.
