// class G4LogicalVolume
|
|
//
|
|
// Class description:
|
|
//
|
|
// Represents a leaf node or unpositioned subtree in the geometry hierarchy.
|
|
// Logical volumes are named, and may have daughters ascribed to them.
|
|
// They are responsible for retrieval of the physical and tracking attributes
|
|
// of the physical volume that it represents: solid, material, magnetic field,
|
|
// and optionally, user limits, sensitive detectors, regions, biasing weights.
|
|
//
|
|
// Get and Set functionality is provided for all attributes, but note that
|
|
// most set functions should not be used when the geometry is `closed'.
|
|
// As a further development, `Guard' checks can be added to ensure
|
|
// only legal operations at tracking time.
|
|
//
|
|
// On construction, solid, material and name must be specified.
|
|
//
|
|
// Daughters are ascribed and managed by means of a simple
|
|
// GetNoDaughters,Get/SetDaughter(n),AddDaughter interface.
|
|
//
|
|
// Smart voxels as used for tracking optimisation. They're also an attribute.
|
|
//
|
|
// Logical volumes self register to the logical volume Store on construction,
|
|
// and deregister on destruction.
|
|
//
|
|
// NOTE: This class is currently *NOT* subclassed, since not meant to
|
|
// act as a base class. Therefore, the destructor is NOT virtual.
|
|
