This class is the central service-provider
class for the channels and selectors of the
java.nio.channels API. A concrete subclass of
SelectorProvider implements factory methods that
return open socket channels, server socket channels, datagram
channels, pipes (with their two internal channels) and
Selector objects. There is one default
SelectorProvider object per JVM: this object can
be obtained with the static SelectorProvider.provider(
) method.
You can specify a custom SelectorProvider
implementation by setting its class name as the value of the system
property java.nio.channels.spi.SelectorProvider.
Or, you can put the class name in a file named
META-INF/services/java.nio.channels.spi.SelectorProvider ,
in your application's JAR file. The
provider( ) method first looks for the
system property, then looks for the JAR file entry. If it finds
neither, it instantiates the implementation's
default SelectorProvider.
Applications are not required to use the default
SelectorProvider exclusively. It is legal to
instantiate other SelectorProvider objects and
explictly invoke their open( ) methods to create
channels in that way.
