    • 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(java.net.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 java.net.SocketAddress>

    • isResolved

      public final boolean isResolved(java.net.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 java.net.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(java.net.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 java.net.SocketAddress>
      Parameters:
      address - the address to resolve
      Returns:
      the SocketAddress as the result of the resolution

    • resolve

      public final Future<T> resolve(java.net.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 java.net.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<java.util.List<T>> resolveAll(java.net.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 java.net.SocketAddress>
      Parameters:
      address - the address to resolve
      Returns:
      the list of the SocketAddresses as the result of the resolution

    • resolveAll

      public final Future<java.util.List<T>> resolveAll(java.net.SocketAddress address, Promise<java.util.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:
      resolveAll in interface AddressResolver<T extends java.net.SocketAddress>
      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

    • doResolve

      protected abstract void doResolve(T unresolvedAddress, Promise<T> promise) throws java.lang.Exception
      Invoked by resolve(SocketAddress) to perform the actual name resolution.
      Throws:
      java.lang.Exception

    • doResolveAll

      protected abstract void doResolveAll(T unresolvedAddress, Promise<java.util.List<T>> promise) throws java.lang.Exception
      Invoked by resolveAll(SocketAddress) to perform the actual name resolution.
      Throws:
      java.lang.Exception
