Description

This function removes an element from the container.

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

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.

Exceptions

Name Thrown on

system_error

key contains an invalid percent‐encoding.

Return Value

An iterator to one past the removed element.

Parameters

Name Description

pos

An iterator to the element.

first,

last The range of params to erase.

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.
