    Parameters:
    
    executor - the EventExecutor which is used to notify the listeners of the Future returned by resolve(SocketAddress)
  - AbstractAddressResolver
```
protected AbstractAddressResolver(EventExecutor executor,
 Class<? extends T> addressType)
```
    Parameters:
    
    executor - the EventExecutor which is used to notify the listeners of the Future returned by resolve(SocketAddress)
    
    addressType - the type of the SocketAddress supported by this resolver
- Method Detail
  - executor
```
protected EventExecutor executor()
```
    Returns the EventExecutor which is used to notify the listeners of the Future returned by resolve(SocketAddress).
  - isSupported
```
public boolean isSupported(SocketAddress address)
```
    Description copied from interface: AddressResolver
    
    Returns true if and only if the specified address is supported by this resolved.
    
    Specified by:
    
    isSupported in interface AddressResolver<T extends SocketAddress>
  - isResolved
```
public final boolean isResolved(SocketAddress address)
```
    Description copied from interface: AddressResolver
    
    Returns true if and only if the specified address has been resolved.
    
    Specified by:
    
    isResolved in interface AddressResolver<T extends SocketAddress>
  - doIsResolved
```
protected abstract boolean doIsResolved(T address)
```
    Invoked by isResolved(SocketAddress) to check if the specified address has been resolved already.
  - resolve
```
public final Future<T> resolve(SocketAddress address)
```
    Description copied from interface: AddressResolver
    
    Resolves the specified address. If the specified address is resolved already, this method does nothing but returning the original address.
    
    Specified by:
    
    resolve in interface AddressResolver<T extends SocketAddress>
    
    Parameters:
    
    address - the address to resolve

    the SocketAddress as the result of the resolution
  - resolve
```
public final Future<T> resolve(SocketAddress address,
 Promise<T> promise)
```
    Description copied from interface: AddressResolver
    
    Resolves the specified address. If the specified address is resolved already, this method does nothing but returning the original address.
    
    Specified by:
    
    resolve in interface AddressResolver<T extends SocketAddress>
    
    Parameters:
    
    address - the address to resolve
    
    promise - the Promise which will be fulfilled when the name resolution is finished
    
    Returns:
    
    the SocketAddress as the result of the resolution
  - resolveAll
```
public final Future<List<T>> resolveAll(SocketAddress address)
```
    Description copied from interface: AddressResolver
    
    Resolves the specified address. If the specified address is resolved already, this method does nothing but returning the original address.
    
    Specified by:
    
    resolveAll in interface AddressResolver<T extends SocketAddress>
    
    Parameters:
    
    address - the address to resolve
    
    Returns:
    
    the list of the SocketAddresses as the result of the resolution
  - resolveAll
```
public final Future<List<T>> resolveAll(SocketAddress address,
 Promise<List<T>> promise)
```
    Description copied from interface: AddressResolver
    
    Resolves the specified address. If the specified address is resolved already, this method does nothing but returning the original address.
    
    Specified by:

    Parameters:
    
    address - the address to resolve
    
    promise - the Promise which will be fulfilled when the name resolution is finished
    
    Returns:
    
    the list of the SocketAddresses as the result of the resolution
