Detailed Description

Class describing an electron reconstructed in the HLT

The HLT reconstructs electrons in a simplified manner before using parts of the offline software to reconstruct electrons in a manner that's very similar to what the offline reconstruction is doing.

Constructor & Destructor Documentation

xAOD::TrigElectron_v1::TrigElectron_v1 (  ) 

Default constructor.

The default constructor doesn't do much, it just sets up the object in a reasonable state. Remember that an object created with this constructor is not usable yet. You either have to add it to a container, or give it a private auxiliary store before setting properties on it.

Member Function Documentation

double xAOD::TrigElectron_v1::e (  )  const [virtual]

The total energy of the particle.

This function gets the energy of the electron using the internal TLorentzVector. Which calculates the energy based on the eta, phi, pt, and m properties.

Returns:
The energy of the electron

Implements xAOD::IParticle.

const TrigElectron_v1::FourMom_t & xAOD::TrigElectron_v1::p4 (  )  const [virtual]

The full 4-momentum of the particle.

This is one of the trickier functions. It provides the 4-momentum of the object as a TLorentzVector. It does this by caching such an object internally, and returning a reference to this cached object.

Returns:
The full 4-momentum of the electron

Implements xAOD::IParticle.

double xAOD::TrigElectron_v1::rapidity (  )  const [virtual]

The true rapidity (y) of the particle.

This function gets the rapidity of the electron using the internal TLorentzVector. Which calculates the rapidity based on the eta, phi, pt, and m properties.

Returns:
The rapidity (y) of the electron

Implements xAOD::IParticle.
