Detailed Description

A representation of a detector in a mosaic camera.

Detector holds both simple data fields (see DetectorBase) and a set of related coordinate systems and transforms, and acts as a container of Amplifier objects.

Detector is immutable, but copies can be modified via one of its Builder classes. A Detector must be created initially as part of a Camera (see Camera::Builder::add), but can then be modified either individually (see Detector::rebuild and Detector::PartialRebuilder) or as part of modifying the full Camera (see Detector::InCameraBuilder).

The coordinate systems and transforms known to a Detector are shared with its parent Camera and all other Detectors in that Camera.

Member Function Documentation

begin()

auto lsst::afw::cameraGeom::Detector::begin ( ) const

inline

An iterator range over amplifers.

Iterators dereference to shared_ptr<Amplifier const>.

Definition at line 278 of file Detector.h.

{ return _amplifiers.begin(); }

cloneStorable()

std::shared_ptr< Storable > lsst::afw::typehandling::Storable::cloneStorable ( ) const

virtualinherited

Create a new object that is a copy of this one (optional operation).

This operation is required for Storables that are stored in GenericMap by value, but not for those stored by shared pointer.

Exceptions

UnsupportedOperationException

Thrown if this object is not cloneable.

Note

If this class supports a clone operation, the two should behave identically except for the formal return type.

When called on Python classes, this method delegates to __deepcopy__ if it exists.

dynamicCast()

template std::shared_ptr< meas::extensions::psfex::PsfexPsf > lsst::afw::table::io::PersistableFacade< Detector >::dynamicCast ( std::shared_ptr< Persistable > const &  ptr )

staticinherited

Dynamically cast a shared_ptr.

Dynamically cast a shared pointer and raise on failure.

You must provide an explicit template instantiation in the .cc file for each class that inherits from PersistableFacade. Designed to work around RTTI issues on macOS with hidden symbols;

Exceptions

lsst::pex::exceptions::LogicError

if the cast fails

param[in] ptr The pointer to be cast.

Returns

The cast pointer.

Exceptions

lsst::pex::exceptions::TypeError

If the dynamic cast fails.

equals()

bool lsst::afw::typehandling::Storable::equals ( Storable const &  other ) const

virtualnoexceptinherited

Compare this object to another Storable.

Subclasses that implement equality comparison must override this method to give results consistent with operator== for all inputs that are accepted by both.

Returns

This implementation returns whether the two objects are the same.

Warning

This method compares an object to any type of Storable, although cross-class comparisons should usually return false. If cross-class comparisons are valid, implementers should take care that they are symmetric and will give the same result no matter what the compile-time types of the left- and right-hand sides are.

singleClassEquals()

template<class T >

static bool lsst::afw::typehandling::Storable::singleClassEquals ( T const &  lhs, Storable const &  rhs  )

inlinestaticprotectedinherited

Test if a Storable is of a particular class and equal to another object.

This method template simplifies implementations of equals that delegate to operator== without supporting cross-class comparisons.

Template Parameters

T	The class expected of the two objects to be compared.

Parameters

lhs,rhs

The objects to compare. Note that rhs need not be a T, while lhs must be.

Returns

true if rhs is a T and lhs == rhs; false otherwise.

Exception Safety

Provides the same level of exception safety as operator==. Most implementations of operator== do not throw.

Note

This method template calls operator== with both arguments of compile-time type T const&. Its use is not recommended if there would be any ambiguity as to which operator== gets picked by overload resolution.

This method template is typically called from equals as:

bool MyType::equals(Storable const& other) const noexcept {
    return singleClassEquals(*this, other);
}

size()

std::size_t lsst::afw::cameraGeom::Detector::size ( ) const

Get the number of amplifiers.

Renamed to __len__ in Python.

{ return _amplifiers.size(); }

toString()

std::string lsst::afw::typehandling::Storable::toString ( ) const

Create a string representation of this object (optional operation).

Exceptions

UnsupportedOperationException

Thrown if this object does not have a string representation.

Note

When called on Python classes, this method delegates to __repr__.

	)		const

Transform a vector of points from one camera system to another.

Template Parameters
