Detailed Description

template<typename _FactoryEntries>
struct Ponca::internal::FactoryBase< _FactoryEntries >

Base class for factory.

This class behaves similarly to ComputeObjectList but do not store any information. It is here to have plain static methods.

Template Parameters

_FactoryEntries

A std::tuple<FactoryEntry>

Member Function Documentation

Filter() [1/2]

template<typename _FactoryEntries >

template<template< typename > class... Preds>

static decltype(auto) Ponca::internal::FactoryBase< _FactoryEntries >::Filter ( )

inlinestatic

Returns a new object that is a filtered version of the current one.

Template Parameters

Preds

List of predicate to filter by

Definition at line 165 of file factory.h.

Filter() [2/2]

template<typename _FactoryEntries >

template<StringLiteral... Names>

static decltype(auto) Ponca::internal::FactoryBase< _FactoryEntries >::Filter ( )

inlinestatic

Returns a new object that is a filtered version of the current one.

Template Parameters

Preds

List of predicate to filter by

Definition at line 174 of file factory.h.

foreach()

template<typename _FactoryEntries >

template<typename Func >

static void Ponca::internal::FactoryBase< _FactoryEntries >::foreach ( Func &&  fun )

inlinestatic

Definition at line 192 of file factory.h.

GetMethod()

template<typename _FactoryEntries >

template<StringLiteral Name>

static decltype(auto) Ponca::internal::FactoryBase< _FactoryEntries >::GetMethod ( )

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

Definition at line 183 of file factory.h.

GetNames()

template<typename _FactoryEntries >

static constexpr decltype(auto) Ponca::internal::FactoryBase< _FactoryEntries >::GetNames ( )

inlinestaticconstexpr

Return the names of the currently held objects.

Definition at line 205 of file factory.h.

size()

template<typename _FactoryEntries >

static constexpr size_t Ponca::internal::FactoryBase< _FactoryEntries >::size ( )

inlinestaticconstexpr

Return the number of object held within the Factory.
