Method Detail

### newByteBuffer

    public static ByteBuffer newByteBuffer(int numElements)

  Allocates a new direct ByteBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

### newDoubleBuffer

    public static DoubleBuffer newDoubleBuffer(int numElements)

  Allocates a new direct DoubleBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

### newFloatBuffer

    public static FloatBuffer newFloatBuffer(int numElements)

  Allocates a new direct FloatBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

### newIntBuffer

    public static IntBuffer newIntBuffer(int numElements)

  Allocates a new direct IntBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

### newLongBuffer

    public static LongBuffer newLongBuffer(int numElements)

  Allocates a new direct LongBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

### newShortBuffer

    public static ShortBuffer newShortBuffer(int numElements)

  Allocates a new direct ShortBuffer with the specified number of elements. The returned buffer will have its byte order set to the host platform's native byte order.

### copyByteBuffer

    public static ByteBuffer copyByteBuffer(ByteBuffer orig)

  Copies the remaining elements (as defined by `limit() - position()`) in the passed ByteBuffer into a newly-allocated direct ByteBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

### copyDoubleBuffer

    public static DoubleBuffer copyDoubleBuffer(DoubleBuffer orig)

  Copies the remaining elements (as defined by `limit() - position()`) in the passed DoubleBuffer into a newly-allocated direct DoubleBuffer. The returned buffer will have its byte order set to the host platform's native byte order. The position of the newly-allocated buffer will be zero, and the position of the passed buffer is unchanged (though its mark is changed).

### copyFloatBuffer

    public static FloatBuffer copyFloatBuffer(FloatBuffer orig)

  Copies the remaining elements (as defined by `limit() - position()`) in the passed FloatBuffer into a newly-allocated direct FloatBuffer.
