This package defines buffer classes that are fundamental to the java.nio API. See Buffer for an overview of buffers, and see ByteBuffer (the most important of the buffer classes) for full documentation of byte buffers. The other type-specific buffer classes are close analogs to ByteBuffer and are documented in terms of that class. See the java.nio.channels package for classes that perform I/O operations on buffers.

Classes

public abstract class Buffer;
   public abstract class ByteBuffer extends Buffer 
   implements Comparable<ByteBuffer>;

   public abstract class CharBuffer extends Buffer 
      implements Comparable<CharBuffer>, Appendable, CharSequence, 
      Readable;
   public abstract class DoubleBuffer extends Buffer 
   implements Comparable<DoubleBuffer>;
   public abstract class FloatBuffer extends Buffer 
   implements Comparable<FloatBuffer>;
   public abstract class IntBuffer extends Buffer 
   implements Comparable<IntBuffer>;
