Source Link

Document

Flushes this output stream and forces any buffered output bytes to be written out.

Usage

From source file:org.apache.cocoon.reading.ImageReader.java

protected byte[] readFully(InputStream in) throws IOException {
    byte tmpbuffer[] = new byte[4096];
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    int i;//  w ww. j  a  va2  s  .  com
    while (-1 != (i = in.read(tmpbuffer))) {
        baos.write(tmpbuffer, 0, i);
    }
    baos.flush();
    return baos.toByteArray();
