Detailed Description
template<typename _FactoryEntries>
struct Ponca::internal::ComputeObjectList< _FactoryEntries >
struct Ponca::internal::ComputeObjectList< _FactoryEntries >
List of compute object that can be iterated over.
Unlike a Factory, this object has non static methods and stores a copy of object.
- Template Parameters
-
_FactoryEntries A std::tuple of FactoryEntry

Applies a function to each entry of the list.
This is expected to be a template function. Example usage is: ComputeObjectList.foreach([&](auto& x) { // Code here should be valid for all possible // types !
// If you know the type, you may run specialized code using CurrentType = std::decay_t<decltype(x)>; if constexpr (std::is_same_v<CurrentType, TheExpectedType>) { // The code goes here. } });
- Template Parameters
-
Func The function to apply to each element
◆ GetMethod()
template<typename _FactoryEntries >
template<StringLiteral Name>
|
inlinestatic |
Return an object by it's id.
In order for this method to work, it is expected that only one method has the specified id !
This method returns the ComputeObject, not a ComputeObjectList !
- Template Parameters
-
id The id of the method
