Implementation of serialization to a tree.

Function Documentation

scalar_flags_val()

template<class T>

type_bits c4::yml::scalar_flags_val ( T const & )

inlinenoexcept

Return extra style flags to use when setting a scalar as val.

Defaults to VAL_PLAIN for arithmetic types, or NOTYPE otherwise

Definition at line 1785 of file tree.hpp.

{
    if constexpr (std::is_arithmetic_v<T>)
        return VAL_PLAIN;
    else
        return NOTYPE;
}

scalar_flags_key()

template<class T>

type_bits c4::yml::scalar_flags_key ( T const & )

inlinenoexcept

Return extra style flags to use when setting a scalar as key.

Defaults to KEY_PLAIN for arithmetic types, or NOTYPE otherwise

Definition at line 1795 of file tree.hpp.

{
    if constexpr (std::is_arithmetic_v<T>)
        return KEY_PLAIN;
    else
        return NOTYPE;
}

write()

template<class T>

void c4::yml::write ( Tree * tree, id_type id, T const & v )

inline

Serialize a variable to the tree's arena, and set it as the node's val.

Definition at line 1838 of file tree.hpp.

{
    tree->set_val(id, serialize_to_arena(tree, v), scalar_flags_val(v));
}

write_key()

template<class T>

void c4::yml::write_key ( Tree * tree, id_type id, T const & v )

inline

Serialize a variable to the tree's arena, and set it as the node's key.

Warning

The key MUST be a scalar value. The tree cannot handle container keys.

Definition at line 1848 of file tree.hpp.

{
    tree->set_key(id, serialize_to_arena(tree, v), scalar_flags_key(v));
}
