variable_info_implementation Namespace Reference

Classes
class	vi_policy_const
	The variable_info policy classes. More...
class	vi_policy_create
	Creates a child table when resolving name if it doesn't exist yet. More...
class	vi_policy_throw
	Will throw an exception when trying to access a nonexistent table. More...
struct	maybe_const
struct	maybe_const< config::child_itors, const vi_policy_const >
struct	variable_info_state
class	info_visitor_base
	Visitor base class. More...
class	get_variable_key_visitor
	Adds a '. More...
class	get_variable_index_visitor
	Appends an [index] to the variable. More...
class	as_scalar_visitor
	Tries to convert it to an (maybe const) attribute value. More...
class	as_container_visitor
	Tries to convert to a [const] config&. More...
class	as_array_visitor
	This currently isn't implemented as a range-based operation because doing it on something like range 2-5 on vi_policy_const if child_ has only 4 elements would be too hard to implement. More...
class	as_range_visitor_base
class	clear_value_visitor
class	exists_as_container_visitor
class	replace_range_h
	Replaces the child in [startindex, endindex) with 'source' 'insert' and 'append' are subcases of this. More...
class	insert_range_h
class	append_range_h
class	merge_range_h

Enumeration Type Documentation

variable_info_state_type

enum variable_info_implementation::variable_info_state_type

Enumerator
state_start	Represents the initial variable state before processing.
state_named	The result of .someval. This can either mean an attribute value or a child range.
state_indexed	The result of .someval[index]. This is never an attribute value and is always a single config.
state_temporary	The result of .length. This value can never be written, it can only be read.

Definition at line 119 of file variable_info_detail.hpp.

Function Documentation

apply_visitor()

template<typename V , typename... T>

V::result_t variable_info_implementation::apply_visitor	(	typename V::param_t	state,
		T &&...	args
	)

Helper function to apply the result of a specified visitor to a variable_info object.

Template Parameters

V	Visitor type.
T	Visitor argument parameter pack.

Parameters

state	Info state (the actual variable data).
args	Arguments to forward to visitor constructor.

Returns

Visitor output in its specified type.

Exceptions

std::range_error

If state has an invalid type_ field.

parse_index()

Parses a ']' terminated string.

This is a important optimization of lexical_cast_default
