# boost::urls::params_encoded_ref::erase

Erase params

## Synopsis

Declared in `<boost/url/params_encoded_ref.hpp>`

    iterator
    erase(iterator pos) noexcept;

## Description

This function removes an element from the container.

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

## Example

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

    params_encoded_ref::iterator it = u.encoded_params().erase( u.encoded_params().begin() );

    assert( u.encoded_query() == "last=Doe" );

## Complexity

Linear in `this‐>url().encoded_query().size()`.

## Exception Safety

Throws nothing.

## Return Value

An iterator to one past the removed element.

## Parameters

Name | Description
--- | ---
pos | An iterator to the element.
