Static Public Member Functions | |
static bool | exists (std::type_index const &baseIndex, std::type_index const &derivedIndex) |

template<class F > | |
static std::vector< PolymorphicCaster const * > const & | lookup (std::type_index const &baseIndex, std::type_index const &derivedIndex, F &&exceptionFunc) |

template<class Derived > | |
static const Derived * | downcast (const void *dptr, std::type_info const &baseInfo) |
Performs a downcast to the derived type using a registered mapping. | |
template<class Derived > | |
static void * | upcast (Derived *const dptr, std::type_info const &baseInfo) |
Performs an upcast to the registered base type using the given a derived type. More... | |

static std::shared_ptr< void > | upcast (std::shared_ptr< Derived > const &dptr, std::type_info const &baseInfo) |
Upcasts for shared pointers. | |
Public Attributes | |
std::map< std::type_index, std::map< std::type_index, std::vector< PolymorphicCaster const * > > > | map |
Maps from base type index to a map from derived type index to caster. | |
std::multimap< std::type_index, std::type_index > | reverseMap |
Holds registered mappings between base and derived types for casting.
This will be allocated as a StaticObject and holds a map containing all registered mappings between base and derived types.

inlinestatic |
Checks if the mapping object that can perform the upcast or downcast.
Uses the type index from the base and derived class to find the matching registered caster. If no matching caster exists, returns false.
|
inlinestatic |
Gets the mapping object that can perform the upcast or downcast.
Uses the type index from the base and derived class to find the matching registered caster. If no matching caster exists, calls the exception function.
The returned PolymorphicCaster is capable of upcasting or downcasting between the two types.
|
inlinestatic |
Performs an upcast to the registered base type using the given a derived type.
The return is untyped because the final casting to the base type must happen in the polymorphic serialization function, where the type is known at compile time
