Member Function Documentation

◆ clone()

virtual IBPtr Herwig::ResonantProcessConstructor::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ doinit()

virtual void Herwig::ResonantProcessConstructor::doinit ( )
protectedvirtual

Initialize this object after the setup phase before saving an EventGenerator to disk.

Exceptions
InitExceptionif object could not be initialized properly.

Reimplemented from Herwig::HardProcessConstructor.

◆ fullclone()

virtual IBPtr Herwig::ResonantProcessConstructor::fullclone ( ) const
protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns
a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

◆ Init()

static void Herwig::ResonantProcessConstructor::Init ( )
static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

◆ operator=()

ResonantProcessConstructor& Herwig::ResonantProcessConstructor::operator= ( const ResonantProcessConstructor )
private

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::ResonantProcessConstructor::persistentInput ( PersistentIStream is,
int  version 
)

Function used to read in object persistently.

Parameters
isthe persistent input stream read from.
versionthe version number of the object when written.

◆ persistentOutput()

void Herwig::ResonantProcessConstructor::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.

◆ search()

tPDSet Herwig::ResonantProcessConstructor::search ( VertexBasePtr  vertex,
long  part1,
direction  d1,
long  part2,
direction  d2,
direction  d3 = outgoing 
)
private

Given a vertex and 2 particle id's find the possible states that can be the 3rd external particle.

Parameters
vertexPointer to the vertex
part1id of first particle
d1direction of particle one
part2id of other particle
d2direction of particle two
d3required direction of 3rd state (default = outgoing)
Returns
container of third particles
