◆ access()

template<class Element, class NameField, class IdField>

template<class Field , class T >

element_type reactions::database::database< Element, NameField, IdField >::access ( T const & v ) const

inlineprotected

Access an element using the field accessor.

◆ all_elements()

template<class Element, class NameField, class IdField>

std::vector<element_type> reactions::database::database< Element, NameField, IdField >::all_elements ( ) const

inline

All the elements in the database file.

Calling this function does not alter the cache. If the cache is enabled a copy of its content is returned. If not, elements are read from the database file.

This function returns the elements in the database and those registered by the user.

◆ clear_cache()

template<class Element, class NameField, class IdField>

void reactions::database::database< Element, NameField, IdField >::clear_cache ( )

inline

Clear the cache, removing also user-registered elements.

◆ disable_cache()

template<class Element, class NameField, class IdField>

void reactions::database::database< Element, NameField, IdField >::disable_cache ( )

inline

Disable the cache.

◆ enable_cache()

template<class Element, class NameField, class IdField>

void reactions::database::database< Element, NameField, IdField >::enable_cache ( )

inline

◆ get_database_path()

template<class Element, class NameField, class IdField>

std::string const& reactions::database::database< Element, NameField, IdField >::get_database_path ( ) const

inline

Get the path to the database file.

◆ open_database()

template<class Element, class NameField, class IdField>

std::ifstream reactions::database::database< Element, NameField, IdField >::open_database ( ) const
