# boost::urls::params_ref::erase

Erase elements

## Synopsis

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

    std::size_t
    erase(
        core::string_view key,
        ignore_case_param ic = {}) noexcept;

## Description

All iterators are invalidated.

## Postconditions

    this->count( key, ic ) == 0

## Complexity

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

## Exception Safety

Throws nothing.

## Return Value

The number of elements removed from the container.

## Parameters

Name | Description
key | The key to match. By default, a case‐sensitive comparison is used.
ic | An optional parameter. If the value `ignore_case` is passed here, the comparison is case‐insensitive.
