Detailed Description

A wrapper around the CRT default host resolution system that uses getaddrinfo() farmed off to separate threads in order to resolve names.

Constructor & Destructor Documentation

DefaultHostResolver() [1/4]

Aws::Crt::Io::DefaultHostResolver::DefaultHostResolver ( EventLoopGroup &  elGroup, size_t  maxHosts, size_t  maxTTL, Allocator *  allocator = ApiAllocator()  )

noexcept

Resolves DNS addresses.

Parameters

elGroup	EventLoopGroup to use.
maxHosts	the number of unique hosts to maintain in the cache.
maxTTL	how long to keep an address in the cache before evicting it.
allocator	memory allocator to use.

DefaultHostResolver() [2/4]

Aws::Crt::Io::DefaultHostResolver::DefaultHostResolver ( size_t  maxHosts, size_t  maxTTL, Allocator *  allocator = ApiAllocator()  )

noexcept

Resolves DNS addresses using the default EventLoopGroup.

For more information on the default EventLoopGroup see Aws::Crt::ApiHandle::GetOrCreateStaticDefaultEventLoopGroup

Parameters

maxHosts	the number of unique hosts to maintain in the cache.
maxTTL	how long to keep an address in the cache before evicting it.
allocator	memory allocator to use.

Member Function Documentation

LastError()

int Aws::Crt::Io::DefaultHostResolver::LastError ( ) const

inlinenoexcept

Returns

the value of the last aws error encountered by operations on this instance.

operator bool()

Aws::Crt::Io::DefaultHostResolver::operator bool ( ) const

inlinenoexcept

Returns

true if the instance is in a valid state, false otherwise.

operator=() [1/2]

DefaultHostResolver& Aws::Crt::Io::DefaultHostResolver::operator= ( const DefaultHostResolver &  )

operator=() [2/2]

delete

ResolveHost()

bool Aws::Crt::Io::DefaultHostResolver::ResolveHost ( const String &  host, const OnHostResolved &  onResolved  )

overridevirtualnoexcept

Kicks off an asynchronous resolution of host. onResolved will be invoked upon completion of the resolution.

Returns

False, the resolution was not attempted. True, onResolved will be called with the result.

Implements Aws::Crt::Io::HostResolver.
