Method

byte[]readFullyAndClose(InputStream input)
read Fully And Close 
ByteBuffer result = ByteBuffer.wrap(new byte[Math.min(512, input.available())]);
while (true) {
    if (result.remaining() == 0) {
        result = ByteBuffer.wrap(Arrays.copyOf(result.array(), result.capacity() * 2));
    int actuallyRead = input.read(result.array(), result.position(), result.remaining());
    if (actuallyRead == -1) {
        break;
...
byte[]readHeaderArea(InputStream in)
read Header Area 
int input = 0;
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
ByteBuffer last4Chars = ByteBuffer.wrap(new byte[4]);
while ((input = in.read()) != -1) {
    byte inputByte = (byte) input;
    buffer.write(inputByte);
    last4Chars.put(inputByte);
    if (emptyLine(last4Chars)) {
...
ByteBufferreadInputStream(InputStream input)
read Input Stream 
byte[] buf = new byte[BUFFER_SIZE];
int idx = 0;
for (;;) {
    int rd = input.read(buf, idx, buf.length - idx);
    if (rd < 0)
        break;
    idx += rd;
    if (idx == buf.length) {
...
StringreadInputStreamToString(InputStream inputStream)
read Input Stream To String 
return readInputStreamToString(inputStream, "UTF-8");
intreadInt(byte[] bytes, int index)
read Int 
ByteBuffer byteBuffer = ByteBuffer.wrap(bytes);
return byteBuffer.getInt(index);
intreadInt(byte[] bytes, int offset, java.nio.ByteOrder byteorder)
read Int 
return java.nio.ByteBuffer.wrap(bytes, offset, 4).order(byteorder).getInt();
intreadInt(byte[] in)
read Int 
return ByteBuffer.wrap(in).getInt();
intreadInt(ByteArrayInputStream bin)
Reads the next 4 bytes from the stream as integer. 
byte[] buffer = new byte[4];
bin.read(buffer);
return ByteBuffer.wrap(buffer).getInt();
intreadInt(InputStream in, ByteOrder order)
read Int 
ByteBuffer buf = ByteBuffer.allocate(4);
buf.order(order);
readFully(in, buf);
return buf.getInt();
intreadInt(InputStream input)
read Int 
byte[] szBytes = new byte[4];
int read = input.read(szBytes);
if (read <= 0) {
    return 0;
return ByteBuffer.wrap(szBytes).getInt();
