Detailed Description

Class to identify a wire inside the CDC.

There are three representations for this:

  • Super-Layer, Layer within the Super-Layer, Wire within the Layer as documented here,
  • Layer as continuous counted through all Super-Layers, Wire within the Layer,
  • Wire number encoded into a single unsigned short. This works as following:
    SuperLayer: bits 1 - 4 (/4096)
    Layer: bits 5 - 7 (% 4096, / 512)
    Wire: bits 8 - 16 (% 512)
    Note: These operations could as well be achieved by bit-shifting operations.

Constructor & Destructor Documentation

◆ WireID() [1/3]

WireID ( unsigned short  eWire = 65535)
inlineexplicit

Constructor taking the encoded wire number.

Parameters
eWireNumber of wire using the encoded format. Careful - wires are not continuously within the encoded number. The default is set to the maximum allowed value, as 0 corresponds already to some wire. This assigned value does NOT correspond to any real wire.

Definition at line 45 of file WireID.h.

Belle2::WireID::m_eWire
unsigned short m_eWire

◆ WireID() [2/3]

WireID ( unsigned short  iSuperLayer,
unsigned short  iLayer,
unsigned short  iWire 
)

Constructor using the official numbering scheme.

Parameters
iSuperLayerNumber of Super-Layer.
iLayerNumber of Layer within the Super-Layer.
iWireWire number within the layer.

Definition at line 35 of file WireID.cc.

37  setWireID(iSuperLayer, iLayer, iWire);

Belle2::WireID::setWireID
void setWireID(unsigned short iSuperLayer, unsigned short iLayer, unsigned short iWire)
Setter using official numbering.
Definition: WireID.h:112

◆ WireID() [3/3]

WireID ( unsigned short  iCLayer,
unsigned short  iWire 
)

Constructor using continuous layer numbers as used in the geometry build-up for the simulation.

Parameters
iCLayerNumber of Layer counted continuously over the full CDC.
iWireNumber of Wire within the layer equivalenty to the official numbering.

Definition at line 30 of file WireID.cc.

Member Function Documentation

◆ getIWire()

unsigned short getIWire ( ) const
inline

Getter for wire within the layer.

This getter works for the official numbering scheme as well as the one used in the geometry build-up.

Definition at line 145 of file WireID.h.

◆ operator=()

WireID& operator= ( unsigned short  eWire)
inline

Assignment from unsigned short.

Parameters
eWireThis parameter should be the wire number in the encoded format.
