Detailed Description

A thin wrapper around std::map to allow aperture corrections to be attached to Exposures.

ApCorrMap simply adds error handling accessors, persistence, and a bit of encapsulation to std::map (given the simplified interface, for instance, we could switch to unordered_map or some other underyling container in the future).

◆ dynamicCast()

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::LogicErrorif the cast fails

param[in] ptr The pointer to be cast.

Returns
The cast pointer.
Exceptions
lsst::pex::exceptions::TypeErrorIf 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.

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

◆ 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
TThe class expected of the two objects to be compared.
Parameters
lhs,rhsThe 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);
}

Definition at line 151 of file Storable.h.

151 {
152 auto typedRhs = dynamic_cast<T const*>(&rhs);

◆ toString()

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

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

Exceptions

Note
