IntBuffer

public abstract class IntBuffer extends Buffer
implements Comparable<IntBuffer>

An int buffer.

This class defines four categories of operations upon int buffers:

  • Absolute and relative get and put methods that read and write single ints;

  • Relative bulk get methods that transfer contiguous sequences of ints from this buffer into an array; and

  • Relative bulk put methods that transfer contiguous sequences of ints from an int array or some other int buffer into this buffer; and

  • Methods for compacting, duplicating, and slicing an int buffer.

Int buffers can be created either by allocation, which allocates space for the buffer's content, by wrapping an existing int array into a buffer, or by creating a view of an existing byte buffer.

Like a byte buffer, an int buffer is either direct or non-direct. A int buffer created via the wrap methods of this class will be non-direct. An int buffer created as a view of a byte buffer will be direct if, and only if, the byte buffer itself is direct. Whether or not an int buffer is direct may be determined by invoking the isDirect method.

Methods in this class that do not otherwise have a value to return are specified to return the buffer upon which they are invoked. This allows method invocations to be chained.

Public Method Summary
