Member Functions

Name	Description
append	Construct element at the last position of the container.
assign	Assignment from initializer list. — Assignment from iterators.
at	Return indexed element with bounds checking. — Return first element matching key with bounds checking.
back	Return last element.
begin	Returns an iterator to the beginning of container.
clear	Clears the contents of the container.
contains	Check if container contains an element with the specified key.
count	Count number of elements with a specified key.
decoded	Return a view of this container as percent-decoded query parameters.
empty	Return true if the container is empty.
end	Returns an iterator to one past the last element.
erase	Erases element from container at position. — Erases range of elements from container. — Erases elements associated with a specified key from container.
find	Find element with a specified key. — Find element with a specified key after specified position.
front	Return first element.
insert	Insert element in container. — Insert elements in container. — Constructs a key-only query parameter at container position. — Constructs a value at container position.
operator=	Assignment. — Assignment from initializer list.
operator[]	Return indexed element.
params_encoded [constructor]	Constructor.
pop_back	Remove element at the last position of the container.
push_back	Insert value at the last position of the container.
remove_value	Remove a value from the container.
replace	Replace container element. — Replace container elements. — Constructs a value at container position. — Constructs a key-only value at container position.
replace_value	Replace element value.
size	Returns the number of query parameters in the url.

Description

The elements of this class dereference directly to the percent-encoded values as string views. This avoids the necessity allocating decoded strings.
