Method

float[]convertFloatBufferToArray(java.nio.FloatBuffer buf)
convert Float Buffer To Array 
if (buf.hasArray()) {
    return buf.array();
} else {
    buf.rewind();
    float[] array = new float[buf.remaining()];
    int index = 0;
    while (buf.hasRemaining()) {
        array[index++] = buf.get();
...
FloatBufferfloatArrayToFloatBuffer(float[] data)
Converts an array of primitive floats to a java.nio.FloatBuffer . 
FloatBuffer ret = ByteBuffer.allocateDirect(data.length << 2).order(ByteOrder.nativeOrder())
        .asFloatBuffer();
ret.put(data).flip();
return ret;
voidfloatBufferToHistogram(FloatBuffer ib, int width, int height, int widthStep, float[] histogram)
float Buffer To Histogram 
Arrays.fill(histogram, 0);
ib.rewind();
int totalPoints = 0;
for (int y = 0; y < height; y++)
    for (int x = 0; x < width; x++) {
        int v = (int) ib.get(y * widthStep + x);
        if (v > 0 && v < histogram.length) {
            histogram[v]++;
...
StringfloatBufferToString(FloatBuffer buffer)
float Buffer To String 
StringBuilder out = new StringBuilder();
for (int i = 0; i < buffer.capacity(); i++) {
    out.append(i).append("=").append(buffer.get(i)).append(" ");
return out.toString();
float[]getFloatArray(final FloatBuffer buff)
get Float Array 
if (buff == null) {
    return null;
buff.clear();
final float[] inds = new float[buff.limit()];
for (int x = 0; x < inds.length; x++) {
    inds[x] = buff.get();
return inds;
float[]getFloatArray(FloatBuffer buff)
Create a new float[] array and populate it with the given FloatBuffer's contents. 
if (buff == null) {
    return null;
buff.clear();
float[] inds = new float[buff.limit()];
for (int x = 0; x < inds.length; x++) {
    inds[x] = buff.get();
return inds;
