Assignment.

Parameters

other	The object from which we're assigning.
warnUnlocked	If true, then warn when we skip unlocked decorations.

We don't copy container/index, as assignment doesn't change where this object is. However, if we have aux data, then we copy aux data if we're copying from an object that also has it; otherwise, if we're copying from an object with no aux data, then we clear ours.

Parameters

name	Name of the aux variable.

This method has to translate from the aux data name to the internal representation each time it is called. Using this method inside of loops is discouraged; instead use the Accessor class.

other	The object from which to copy.
warnUnlocked	If true, then warn when we skip unlocked decorations.

If this object has no associated store, this does nothing. If the associated aux data is const, this throws ExcConstAuxData.

          return -1.0;
       }
       return weightTrackAcc( *this )[ i ];
    }

◆ trackWeights()

const std::vector< float >& xAOD::Vertex_v1::trackWeights ( ) const

Get all the track weights.

◆ type()

Type::ObjectType xAOD::Vertex_v1::type ( ) const

A little helper function for identifying the type in template code.

Definition at line 58 of file Vertex_v1.cxx.

                                         {
  
       return Type::Vertex;
    }

◆ usingPrivateStore()

bool SG::AuxElement::usingPrivateStore ( ) const

inherited

Test to see if this object is currently using a private store.

Definition at line 280 of file AuxElement.cxx.

 {
   return havePrivateData() && 
     typeid(*m_container) == typeid(AuxElementPrivateData);
 }

◆ usingStandaloneStore()

bool SG::AuxElement::usingStandaloneStore ( ) const

inherited

Test to see if this object is currently using a standalone store.

Test to see if this object is currently using a private store.

Definition at line 290 of file AuxElement.cxx.

 {
   return havePrivateData() &&
     typeid(*m_container) == typeid(AuxElementStandaloneData);
 }

◆ vertexType()

VxType::VertexType xAOD::Vertex_v1::vertexType ( ) const

The type of the vertex.

◆ vxTrackAtVertex() [1/2]

std::vector< Trk::VxTrackAtVertex > & xAOD::Vertex_v1::vxTrackAtVertex ( )

Non-const access to the VxTrackAtVertex vector.

This function can be used to attach an Athena-only, reconstruction specific information to the object.

The data is attached as a dynamic auxiliary property. And it needs to be explicitly disabled for writing out, as we don't have a valid dictionary for it. Not to mention that these objects are very large.

Returns: A modifiable object, creating it if necessary

Definition at line 181 of file Vertex_v1.cxx.

                                                                {
  
       return vxVertAcc( *this );
    }

◆ vxTrackAtVertex() [2/2]

const std::vector< Trk::VxTrackAtVertex > & xAOD::Vertex_v1::vxTrackAtVertex ( ) const

Const access to the vector of tracks fitted to the vertex (may not exist!)

This function can be used to access the Athena-only, reconstruction specific decoration on the object.

Keep in mind that this decoration is not available for most of the vertices. When calling this function on an object that doesn't have this decoration, an exception will be thrown. Use the vxTrackAtVertexAvailable() function to check if this function will succeed or not.

Returns: A constant reference to the decoration

Definition at line 198 of file Vertex_v1.cxx.

                                     {
  
       return vxVertAcc( *this );
    }

◆ vxTrackAtVertexAvailable()

bool xAOD::Vertex_v1::vxTrackAtVertexAvailable ( ) const

Check if VxTrackAtVertices are attached to the object.

This function can be used to check whether this Athena-only, reconstruction-specific decoration is available on the object.

In most cases it isn't.

Returns: The availablility of the decoration

Definition at line 209 of file Vertex_v1.cxx.

                                                   {
  
       return vxVertAcc.isAvailable( *this );
    }

◆ x()

float xAOD::Vertex_v1::x ( ) const

Returns the x position.

◆ y()

float xAOD::Vertex_v1::y ( ) const

Returns the y position.

◆ z()

float xAOD::Vertex_v1::z ( ) const

Returns the z position.

Member Data Documentation

◆ m_container

const SG::AuxVectorData* SG::ConstAuxElement::m_container

privateinherited

The container of which this object is an element.

Should be null if this object is not within a container, except that it may also point at a private store.

Definition at line 335 of file AuxElement.h.

◆ m_covariance

CxxUtils::CachedValue<AmgSymMatrix(3)> xAOD::Vertex_v1::m_covariance

private

Cached covariance of the vertex.

Definition at line 193 of file Vertex_v1.h.

◆ m_index

size_t SG::IAuxElement::m_index

privateinherited

The index of this element within its container.

Should be 0 if this object is not within a container.

Definition at line 128 of file IAuxElement.h.

◆ m_position

CxxUtils::CachedValue<Amg::Vector3D> xAOD::Vertex_v1::m_position

private

Cached position of the vertex.

Definition at line 191 of file Vertex_v1.h.

◆ m_privateStoreState

PrivateStoreState SG::IAuxElement::m_privateStoreState

privateinherited

Definition at line 137 of file IAuxElement.h.

◆ supportsThinning

constexpr bool SG::AuxElement::supportsThinning = true

staticconstexprinherited

Mark that this type supports thinning operations.

See AthContainers/supportsThinning.h and AthenaPoolCnvSvc/T_AthenaPoolCnv.h. Helps guide which pool converter template will be used. If false, the default pool converter will be used rather than the aux store-specific one. Ordinary xAOD type should not touch this, but may be overridden in a derived class to handle certain special cases.
