abstract member InheritedChannel : unit -> Java.Nio.Channels.IChannel
override this.InheritedChannel : unit -> Java.Nio.Channels.IChannel

Returns

The inherited channel, if any, otherwise null.

Attributes

if an I/O error occurs.

Remarks

Returns the channel inherited from the entity that created this Java virtual machine.

On many operating systems a process, such as a Java virtual machine, can be started in a manner that allows the process to inherit a channel from the entity that created the process. The manner in which this is done is system dependent, as are the possible entities to which the channel may be connected. For example, on UNIX systems, the Internet services daemon (inetd) is used to start programs to service requests when a request arrives on an associated network port. In this example, the process that is started, inherits a channel representing a network socket.

In cases where the inherited channel represents a network socket then the java.nio.channels.Channel Channel type returned by this method is determined as follows:

<ul>

<li>

If the inherited channel represents a stream-oriented connected socket then a java.nio.channels.SocketChannel SocketChannel is returned. The socket channel is, at least initially, in blocking mode, bound to a socket address, and connected to a peer.

</li>

<li>

If the inherited channel represents a stream-oriented listening socket then a java.nio.channels.ServerSocketChannel ServerSocketChannel is returned. The server-socket channel is, at least initially, in blocking mode, and bound to a socket address.

</li>

<li>

If the inherited channel is a datagram-oriented socket then a java.nio.channels.DatagramChannel DatagramChannel is returned. The datagram channel is, at least initially, in blocking mode, and bound to a socket address.

</li>

</ul>

In addition to the network-oriented channels described, this method may return other kinds of channels in the future.

The first invocation of this method creates the channel that is returned. Subsequent invocations of this method return the same channel.
