provider back to summary

provider	back to summary
public static AsynchronousChannelProvider provider() Returns the system-wide default asynchronous channel provider for this invocation of the Java virtual machine. The first invocation of this method locates the default provider object as follows: If the system property `java.nio.channels.spi.AsynchronousChannelProvider` is defined then it is taken to be the fully-qualified name of a concrete provider class. The class is loaded and instantiated; if this process fails then an unspecified error is thrown. If a provider class has been installed in a jar file that is visible to the system class loader, and that jar file contains a provider-configuration file named `java.nio.channels.spi.AsynchronousChannelProvider` in the resource directory `META-INF/services`, then the first class name specified in that file is taken. The class is loaded and instantiated; if this process fails then an unspecified error is thrown. Finally, if no provider has been specified by any of the above means then the system-default provider class is instantiated and the result is returned. Subsequent invocations of this method return the provider that was returned by the first invocation. Returns:AsynchronousChannelProvider The system-wide default AsynchronousChannel provider

public static AsynchronousChannelProvider provider()
