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.

Public Method Summary

static FloatBuffer
allocate(int capacity)
Allocates a new float buffer.
final float[]
Returns the float array that backs this buffer  (optional operation).
final int
Returns the offset within this buffer's backing array of the first element of the buffer  (optional operation).
abstract FloatBuffer
Creates a new, read-only float buffer that shares this buffer's content.
abstract FloatBuffer
Compacts this buffer  (optional operation).
