Detailed Description

Class managing the creation of a new recob::Wire object.

In order to be as simple as possible (Plain Old Data), data products like recob::Wire need to be stripped of most of their functions, including the ability to communicate whether a value we try to store is invalid (that would require a art::Exception – art – or at least a message on the screen – MessageFacility) and the ability to read things from event, services (e.g. geometry) etc.

A Creator is a class that creates a temporary data product, and at the end it yields it to the caller for storage. This last step should be by move construction, although a copy method is also provided.

An example of creating a Wire object:

// let RoIsignal be a recob::Wire::RegionsOfInterest_t already filled
// with the signal regions, and rawdigit the raw::RawDigit of the
// channel; RoIsignal will become empty
recob::WireCreator wire(std::move(RoIsignal), rawdigit);
wires.push_back(wire.move()); // wire content is not valid any more

This is a one-step creation object: the wire is constructed at the same time the WireCreator is, and no facility is offered to modify the constructed wire, or to create another one.

Constructor & Destructor Documentation

recob::WireCreator::WireCreator	(	const RegionsOfInterest_t &	sigROIlist,
		const raw::RawDigit &	rawdigit
	)

Constructor: uses specified signal in regions of interest.

Parameters

sigROIlist	signal organized in regions of interest
rawdigit	the raw digit this channel is associated to

The information used from the raw digit are the channel ID and the length in samples (TDC ticks) of the original readout window.

Definition at line 28 of file WireCreator.cxx.

References recob::Wire::fSignalROI, lar::sparse_vector< T >::resize(), raw::RawDigit::Samples(), and wire.

    : wire(sigROIlist,
           rawdigit.Channel(),
           art::ServiceHandle<geo::Geometry const>()->View(rawdigit.Channel()))
  {
    // resize fSignalROI again:
    // just in case the user hasn't cared to set sigROIlist size right
    wire.fSignalROI.resize(rawdigit.Samples());
  } // Wire::Wire(RegionsOfInterest_t&)

recob::WireCreator::WireCreator	(	RegionsOfInterest_t &&	sigROIlist,
		const raw::RawDigit &	rawdigit
	)

Constructor: uses specified signal in regions of interest.

Parameters

sigROIlist	signal organized in regions of interest
rawdigit	the raw digit this channel is associated to

The information used from the raw digit are the channel ID and the length in samples (TDC ticks) of the original readout window.

Signal information is moved from sigROIlist, that becomes empty.

    : wire(std::move(sigROIlist),
           rawdigit.Channel(),
           art::ServiceHandle<geo::Geometry const>()->View(rawdigit.Channel()))
  {
    // resize fSignalROI again:
    // just in case the user hasn't cared to set sigROIlist size right
    wire.fSignalROI.resize(rawdigit.Samples());
  } // Wire::Wire(RegionsOfInterest_t&)

recob::WireCreator::WireCreator	(	RegionsOfInterest_t const &	sigROIlist,
		raw::ChannelID_t	channel,
		geo::View_t	view
	)

Constructor: uses specified signal in regions of interest.

Parameters

sigROIlist	signal organized in regions of interest
channel	the ID of the channel
view	the view the channel belongs to

The information used from the raw digit are the channel ID and the length in samples (TDC ticks) of the original readout window.

Definition at line 50 of file WireCreator.cxx.

    : wire(sigROIlist, channel, view)
  {}

recob::WireCreator::WireCreator	(	RegionsOfInterest_t &&	sigROIlist,
		raw::ChannelID_t	channel,
		geo::View_t	view
	)

Constructor: uses specified signal in regions of interest.

Parameters

sigROIlist	signal organized in regions of interest
channel	the ID of the channel
view	the view the channel belongs to

The information used from the raw digit are the channel ID and the length in samples (TDC ticks) of the original readout window.

Signal information is moved from sigROIlist, that becomes empty.

    : wire(std::move(sigROIlist), channel, view)
  {}

Member Function Documentation

const Wire& recob::WireCreator::copy ( ) const

inline

Returns the constructed wire.

Returns

a constant reference to the constructed wire

Despite the name, no copy happens in this function. Copy takes place in the caller code as proper; for example:

// be wire a WireCreator instance:
std::vector<recob::Wire> Wires;
wire.copy();                          // nothing happens
Wires.push_back(wire.copy());         // here a copy happens
recob::Wire single_wire(wire.copy()); // wire is copied again

Definition at line 138 of file WireCreator.h.

{ return wire; }

Wire&& recob::WireCreator::move ( )

inline

Prepares the constructed wire to be moved away.

Returns

a right-value reference to the constructed wire

Despite the name, no move happens in this function. Move takes place in the caller code as proper; for example:

// be wire a WireCreator instance:
std::vector<recob::Wire> Wires;
wire.move();                          // nothing happens
Wires.push_back(wire.move());         // here the copy happens
recob::Wire single_wire(wire.move()); // wrong! wire is empty now

Definition at line 122 of file WireCreator.h.

{ return std::move(wire); }
