java.lang.Object java.nio.channels.spi.SelectorProviderService-provider class for selectors and selectable channels.
A selector provider is a concrete subclass of this class that has a zero-argument constructor and implements the abstract methods specified below. A given invocation of the Java virtual machine maintains a single system-wide default provider instance, which is returned by the provider method. The first invocation of that method will locate the default provider as specified below.
The system-wide default provider is used by the static open methods of the DatagramChannel , Pipe , Selector , ServerSocketChannel , and SocketChannel classes. It is also used by the System.inheritedChannel() method. A program may make use of a provider other than the default provider by instantiating that provider and then directly invoking the open methods defined in this class.
All of the methods in this class are safe for use by multiple concurrent threads.

public Channel inheritedChannel() throws IOException
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 Channel type returned by this method is determined as follows:
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.

The first invocation of this method locates the default provider object as follows:
Subsequent invocations of this method return the provider that was returned by the first invocation.
