Appendix C. NIO Quick Reference

I still haven’t found what I’m looking for.

U2

This appendix is a quick reference to the NIO classes and interfaces. Packages, classes, and methods are sorted alphabetically to make things easier to find. The API listings were created programmatically using the Java Reflection API to extract information directly from the compiled class files of the JDK. Regular expressions (autogenerated from the class information) were used to retrieve parameter names from the source. Descriptive text (such as this) was composed in XML then processed by an XSL stylesheet to merge with the API information (by invoking the Java code as an extension function) for each class.

The same convention is used here as in the main text. A missing semicolon at the end of a method signature implies that the method body follows in the source. Abstract methods end with a semicolon because they have no concrete body. The values to which constants are initialized are not listed.

This reference was generated against the J2SE 1.4.0 release.

Package java.nio

The java.nio package contains Buffer classes used by classes in the java.nio.channels and java.nio.charset subpackages.

Buffer

Buffer is the base class from which all other buffer classes extend. It contains generic methods common to all buffer types.

public abstract class Buffer
{
    public final int capacity()
    public final Buffer clear()
    public final Buffer flip()
    public final boolean hasRemaining()
    public abstract boolean isReadOnly ...
