FloatBuffer

public abstract class FloatBuffer extends Buffer
implements Comparable<FloatBuffer>

A float buffer.

This class defines four categories of operations upon float buffers:

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

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

  • Relative bulk put methods that transfer contiguous sequences of floats from a float array or some other float buffer into this buffer; and

  • Methods for compacting, duplicating, and slicing a float buffer.

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

Like a byte buffer, a float buffer is either direct or non-direct. A float buffer created via the wrap methods of this class will be non-direct. A float 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 a float 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.
