Description

The list of methods to do InputStream Read All are organized into topic(s).

Method

byte[]readAll(final InputStream is)
Read all data from input stream 
int dataLength = 0;
int byteOffset = 0;
int blockSize = 8000;
byte[] buffer = null;
do {
    byte[] tmpBuf = new byte[blockSize];
    dataLength = is.read(tmpBuf, 0, tmpBuf.length);
    if (dataLength != -1) {
...
intreadAll(InputStream i, byte b[])
Reads until the array is full or until the stream ends 
int len = b.length;
int n = 0;
while (n < len) {
    int count = i.read(b, n, len - n);
    if (count < 0) {
        return n;
    n += count;
...
byte[]readAll(InputStream in)
read All 
byte[] result = new byte[in.available()];
in.read(result);
return result;
byte[]readall(InputStream in)
readall 
byte[] buf = new byte[4096];
int off = 0;
while (true) {
    if (off == buf.length) {
        byte[] n = new byte[buf.length * 2];
        System.arraycopy(buf, 0, n, 0, buf.length);
        buf = n;
    int ret = in.read(buf, off, buf.length - off);
    if (ret < 0) {
        byte[] n = new byte[off];
        System.arraycopy(buf, 0, n, 0, off);
        return (n);
    off += ret;
byte[]readAll(InputStream in)
Read an entire stream and return byte[]. 
final int CHUNK = 16 * 1024;
int total = 0;
byte[] buf = new byte[CHUNK * 2];
int read = in.read(buf);
if (read > 0)
    total += read;
while (read != -1) {
    if (buf.length - total < CHUNK) {
...
byte[]readAll(InputStream in)
Reads all data from the given input stream. 
return readAll(in, DEFAULT_BUFFER_SIZE);
StringreadAll(InputStream in)
Read all bytes available on the input stream, and concatenates them into a string. 
StringBuilder bob = new StringBuilder();
int c;
while ((c = in.read()) != -1) {
    bob.append((char) c);
return bob.toString();
StringreadAll(InputStream in)
read All 
StringBuffer b = new StringBuffer();
int c;
while ((c = in.read()) != -1) {
    b.append((char) c);
return b.toString();
intreadAll(InputStream in, byte[] buffer, int off, int len)
Continue reading from a stream until EOF is reached, or the requested number of bytes is read. 
int soFar = 0;
while (soFar < len) {
    int n = in.read(buffer, off + soFar, len - soFar);
    if (n < 0) {
        return soFar;
    soFar += n;
return len;
intreadall(InputStream in, byte[] buffer, int offset, int len)
Receives data. 
int total = 0;
for (;;) {
    int received = in.read(buffer, offset, len);
    if (received < 0) {
        return total;
    total += received;
    offset += received;
