int interop_atom_term_select_int(const AtomStringIntPair *table, term atom, GlobalContext *global)

Finds on a table the first matching atom string.

Allows to quickly translate atoms to any integer constant. This function is useful for creating switch statements for atom values. A linear search is performed, so table entries should be sorted by frequency.

Parameters:

• table – an array AtomStringIntPair structs, terminated with a default entry marked with SELECT_INT_DEFAULT macro.

• atom – the atom used for comparison.

• global – the global context.

Returns:

the found int value which corresponds to the given atom.

term interop_kv_get_value_default(term kv, AtomString key, term default_value, GlobalContext *glb)

Get a value given a key (as AtomString) from any proplist or map.

This function allows to easily get values from proplists or maps, without poluting the atom table.

Parameters:

• kv – any proplist or map.

• key – an AtomString, such as ATOM_STR(“\x3”, “key”).

• default_value – that is returned in case of missing item.

• glb – the global context.

Returns:

the value term in case given key exists, otherwise the default_value.

term interop_atom_term_select_atom(const AtomStringIntPair *table, int value, GlobalContext *global)

Finds the first matching atom in an atoms table .

Allows to quickly translate integer constants to an atom in an atoms table. This function is the inverse of interop_atom_term_select_int.

Parameters:

• table – an array AtomStringIntPair structs, terminated with a default entry marked with SELECT_INT_DEFAULT macro.

• value – the in value used for comparison.

• global – the global context.

Returns:

the found atom which corresponds to the given int value, or the invalid term, if there is no such value in the table.
