fcf::TypeInfo class

Type:

class fcf::TypeInfo

File: bits/PartType/TypeInfoDefinition.hpp

Available from version: 1.0.1

Structure containing metadata and runtime information for a registered type.

fcf::TypeInfo is the core descriptor used by the fcf type system to perform dynamic type checking, conversions, and specifier-based operations.

The structure is initialized by the framework itself. Type information can be obtained using the fcf::getTypeInfo function or the fcf::Type::typeInfo method.

Typedef

typedef ConvertersType - The type is a map for storing converter functions.

typedef SpecifiersType - Map type of the mapping from the specifier type index to the specifier information

Properties

fcf::TypeIndex index

- Unique identifier for the type

std::string name

- The human-readable name of the type.

unsigned char flags

- Internal flags for framework operation

size_t size

- The size of a data type in bytes.

fcf::TypeInfo::ConvertersType converters

- Map of conversion functions for converting FROM this type.

fcf::TypeInfo::ConvertersType backConverters

- Map of conversion functions for converting TO this type.

fcf::TypeInfo::SpecifiersType specifiers

- Registered specifiers (e.g., Less, Equal, Add) for this type

fcf::UniversalCall containerAccessUniversalCall

- Universal call for the container access specifier for fast access.

fcf::ResolveSpecifier::CallType resolveCall

- The function pointer for the "resolve" specifier for fast access.

size_t variantInnerSize

- Filled for type fcf::Variant, stores the size of the inner buffer. Necessary for internal framework work.

fcf::TypeFactoryBase* initializer

- A pointer to a factory object used to create/destroy instances of this type.

Methods

template <typename TSpecifier>
TSpecifier::CallType specifierCall()

template <typename TSpecifier>
TSpecifier::CallType specifierCall(fcf::Exception* a_dstError)

- Retrieves a specifier call as a pointer to a specialized function for the given specifier.

template <typename TSpecifier>
fcf::UniversalCall specifierUniversalCall()

template <typename TSpecifier>
fcf::UniversalCall specifierUniversalCall(fcf::Exception* a_dstError)

- Retrieves a universal call function pointer for the given specifier.

Example:

#include <iostream> // Define an implementation macro to include the implementation section in header files. #define FCF_BASIS_IMPLEMENTATION #include <fcfBasis/basis.hpp> int main() { // We get information about the type const fcf::TypeInfo* ti = fcf::Type< std::string* >().typeInfo(); std::cout << "Type index: 0x" << std::hex << ti->index << std::dec << std::endl; std::cout << "Type name: " << ti->name << std::endl; std::cout << "Type size: " << ti->size << std::endl; return 0; }

Output:

Type index: 0x1000001e Type name: std::string* Type size: 8
