Replace params.

Synopsis

iterator
replace(
    iterator pos,
    param_pct_view const& p);

Description

This function replaces the contents of the element at pos with the specified param.

All iterators that are equal to pos or come after are invalidated.

Remarks

The strings passed in must not come from the element being replaced, or else the behavior is undefined.

Example

url u( "?first=John&last=Doe" );

u.encoded_params().replace( u.encoded_params().begin(), { "title", "Mr" });

assert( u.encoded_query() == "title=Mr&last=Doe" );

Complexity

Linear in this->url().encoded_query().size().

Exception Safety

Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.

Exceptions

Return Value

An iterator to the element.
