Member Function Documentation

create()

virtual void create ( const GearDir &  content, G4LogicalVolume &  topVolume, geometry::GeometryTypes  type  )

inlineoverridevirtual

The old create member: create the configuration object(s) on the fly and call the geometry creation routine.

If more than one object is needed adjust accordingly

Implements CreatorBase.

Definition at line 71 of file DBCreatorExample.cc.

    {
      MyDBPayloadClass config = createConfiguration(content);
      createGeometry(config, topVolume, type);
    }

createConfiguration()

MyDBPayloadClass createConfiguration ( const GearDir &  param )

private

Create a parameter object from the Gearbox XML parameters.

If more than one object is created these could be assigned to members or you could return a tuple.

createFromDB()

virtual void createFromDB ( const std::string &  name, G4LogicalVolume &  topVolume, geometry::GeometryTypes  type  )

inlineoverridevirtual

Create the geometry from the Database.

Reimplemented from CreatorBase.

Definition at line 87 of file DBCreatorExample.cc.

    {
      DBObjPtr<MyDBPayloadClass> dbObj;
      if (!dbObj) {
        // Check that we found the object and if not report the problem
        B2FATAL("No configuration for " << name << " found.");
      }
      createGeometry(*dbObj, topVolume, type);
    }

createGeometry()

void createGeometry ( const MyDBPayloadClass &  parameters, G4LogicalVolume &  topVolume, geometry::GeometryTypes  type  )

private

Create the geometry from a parameter object.

If more than one object is needed these could instead be taken from member variables or the number of parameters could be increased.

createPayloads()

virtual void createPayloads ( const GearDir &  content, const IntervalOfValidity &  iov  )

inlineoverridevirtual

Create the configuration objects and save them in the Database.

If more than one object is needed adjust accordingly

Reimplemented from CreatorBase.

Definition at line 79 of file DBCreatorExample.cc.

    {
      DBImportObjPtr<MyDBPayloadClass> importObj;
      importObj.construct(createConfiguration(content));
      importObj.import(iov);
    }
