Class VMChannel.State

java.lang.Object

gnu.java.nio.VMChannel.State

Enclosing class:

VMChannel

public final class VMChannel.State
extends Object

A wrapper for a native file descriptor integer. This tracks the state of an open file descriptor, and ensures that This class need not be fully supported by virtual machines; if a virtual machine does not use integer file descriptors, or does and wishes to hide that, then the methods of this class may be stubbed out. System-specific classes that depend on access to native file descriptor integers SHOULD declare this fact.
