Detailed Description

Interface for a class providing readout channel mapping to geometry.

Note

A number of methods react specifically when provided with invalid IDs as arguments. An invalid ID is an ID with the isValid flag unset, or, in case of channel IDs, an ID with value raw::InvalidChannelID. An ID that does not present this feature is by definition "valid"; this does not imply that the represented entity (channel, geometry entity or readout group) actually exists. The behaviour of the methods to valid, non-existent IDs should be considered undefined, and it is recommended that the existence of the entity is checked beforehand. Unless the documentation explicitly defines a behaviour, an undefined behaviour should be assumed; nevertheless, the documentation of some of the methods still reminds of this.

     { return map[id.Cryostat][id.TPC].size(); }

size_t geo::ChannelMapAlg::ChannelToAuxDet ( std::vector< geo::AuxDetGeo > const &  auxDets, std::string const &  detName, uint32_t const &  channel  ) const

virtual

Returns the index of the detector containing the specified channel.

Parameters

auxDets	list of the auxiliary detectors
detName	name of the auxiliary detector being investigated
channel	number of the channel within that auxiliary detector

Returns

index of the sought auxiliary detector within auxDets

Bug:

This function is somehow broken in that it ignores the auxDets in the arguments and instead relies on a cache that is never filled by this class (derived classes can fill it though).

Definition at line 152 of file ChannelMapAlg.cxx.

  {
    // loop over the map of AuxDet names to Geo object numbers to determine which auxdet
    // we have.  If no name in the map matches the provided string, throw an exception
    for(auto itr : fADNameToGeo)
      if( itr.first.compare(detName) == 0 ) return itr.second;

    return UINT_MAX;
  }

virtual readout::ROPID geo::ChannelMapAlg::ChannelToROP ( raw::ChannelID_t  channel ) const

pure virtual

Returns the ID of the ROP the channel belongs to.

Returns

the ID of the ROP the channel belongs to (invalid if channel is)

See Also

HasChannel()

The channel must exist, or be the invalid channel value. With a channel that is not present in the mapping and that is not the invalid channel (raw::InvalidChannelID), the result is undefined.

Implemented in icarus::ICARUSChannelMapAlg, and geo::ChannelMapStandardAlg.

Parameters

auxDets	list of the sensitive auxiliary detectors
detName	name of the auxiliary detector being investigated
channel	number of the channel within that auxiliary detector

Parameters

ropid

ID of the readout plane

Returns

ID of first channel, or raw::InvalidChannelID if ID is invalid

bool geo::ChannelMapAlg::IsValidOpChannel ( unsigned int  opChannel, unsigned int  NOpDets  ) const

virtual

Returns whether the ID identifies a valid optical detector channel.

Parameters

opChannel	channel number
NOpDets	number of optical detectors in the detector

Returns

whether opChannel would be a valid channel

The specification of the number of optical channels reflects the logic described in NOpChannel().

    if (hChan >= this->NOpHardwareChannels(opdet)) return false;

    return true;
  }

unsigned int geo::ChannelMapAlg::MaxOpChannel ( unsigned int  NOpDets ) const

virtual

Returns the number of optical channels contained in some detectors.

Parameters

NOpDets

number of optical detectors

Returns

optical channels contained in NOpDets detectors

This function returns the first optical channel ID larger than the last channel ID in a detector with NOpDets optical detectors (with the same logic as NOpChannels()). For example, in a detector with 32 channels with contiguous IDs starting at 0, this function would return 32. If the channels started with ID 1, this function would instead return 33 and if there were a 16 channel gap, so that valid channels are from 0 to 15 and from 32 to 47, this function would return 48.

inlinevirtual

Returns the ID of the wire nearest to the specified position.

Parameters

worldPos	position to be tested
planeID	plane containing the wire

Returns

the ID of the wire closest to worldPos in the specified plane

Exceptions

InvalidWireIDError

the ID found is not present in the detector

See Also

WireCoordinate(double, double, geo::PlaneID const&)

The plane is required to be valid and exist in the detector. Otherwise, the behaviour is undefined. An exception is thrown if the wire that would be the closest is actually not present; but no check is performed whether the specified position is outside the wire plane: wires are extrapolated to be infinitely long. In other words, the result can be trusted only as long as the position is within the specified wire plane.

unsigned int geo::ChannelMapAlg::NOpChannels ( unsigned int  NOpDets ) const

virtual

Returns the number of optical channels contained in some detectors.

Parameters

NOpDets

number of optical detectors

Returns

optical channels contained in NOpDets detectors

This function returns how many channels can be expected to be present in a detector with NOpDets optical detectors. This is an upper limit, as not all channels have necessarily to be present.

For example: if a detector has four channels per optical detector, the returned value will be four times the argument NOpDets. If there is a single channel on each optical detector, the return value will be the value NOpDets (this is in fact the fallback implementation). If each optical detector can have anywhere between 2 and 12 channels, the returned value is 12 times NOpDets, and it will be an overestimation of the number of channels.

Definition at line 22 of file ChannelMapAlg.cxx.

  {
    // By default just return the number of optical detectos
    return NOpDets;
  }

unsigned int geo::ChannelMapAlg::NOpHardwareChannels ( unsigned int  opDet ) const

virtual

Returns the number of channels in the specified optical detectors.

Parameters

opDet

ID of the chosen optical detector

Returns

optical channels contained in optical detector with ID opDet

This function returns how many channels are actually present in the optical detector with the specified ID.

For example: if a detector has four channels per optical detector, the returned value will be four, regardless opDet, and . If there is a single channel on each optical detector, the return value will be 1, again ignoring opDet (this is in fact the fallback implementation). If each optical detector can have anywhere between 2 and 12 channels, the returned value will be 2, 12, etc., that is the exact number of channels in opDet.

Although implementations are encouraged to return 0 on invalid optical detectors, the actual return value in that case is undefined.
