Detailed Description

Base class for projections which define a spatial basis.

A pure virtual interface for projections which define a set of 3 basis vectors. This allows e.g. Thrust and Sphericity to be used interchangeably as defining bases for e.g. hemisphere mass and broadening calculations.

axis1()

virtual const Vector3 & Rivet::AxesDefinition::axis1 ( ) const

pure virtual

Axis accessors, in decreasing order of significance. The main axis.

Implemented in Rivet::Sphericity, Rivet::Spherocity, and Rivet::Thrust.

axis2()

virtual const Vector3 & Rivet::AxesDefinition::axis2 ( ) const

pure virtual

The 2nd most significant ("major") axis.

Implemented in Rivet::Sphericity, Rivet::Spherocity, and Rivet::Thrust.

axis3()

virtual const Vector3 & Rivet::AxesDefinition::axis3 ( ) const

pure virtual

The least significant ("minor") axis.

Implemented in Rivet::Sphericity, Rivet::Spherocity, and Rivet::Thrust.

before()

bool Rivet::Projection::before ( const Projection &  p ) const

inherited

Determine whether this object should be ordered before the object p given as argument. If p is of a different class than this, the before() function of the corresponding type_info objects is used. Otherwise, if the objects are of the same class, the virtual compare(const Projection &) will be returned.

clone()

virtual unique_ptr< Projection > Rivet::AxesDefinition::clone ( ) const

pure virtual

Clone on the heap.

Implements Rivet::Projection.

compare()

virtual CmpState Rivet::Projection::compare ( const Projection &  p ) const

pure virtualinherited

This function is used to define a unique ordering between different Projection objects of the same class. If this is considered to be equivalent to the Projector object, p, in the argument the function should return 0. If this object should be ordered before p a negative value should be returned, otherwise a positive value should be returned. This function must never be called explicitly, but should only be called from the operator<(const Projection &). When implementing the function in concrete sub-classes, it is then guaranteed that the Projection object p in the argument is of the same class as the sub-class and can be safely dynamically casted to that class.

When implementing this function in a sub-class, the immediate base class version of the function should be called first. If the base class function returns a non-zero value, that value should be returned immediately. Only if zero is returned should this function check the member variables of the sub-class to determine whether this should be ordered before or after p, or if it is equivalent with p.
