Creates a piped output stream that is not yet connected to a piped input stream.

Usage

From source file:pt.ua.tm.neji.util.ZipGenerator.java

/**
 * Builds a zip file generator that stores in it the specified root folder and its sub-folders and sub-files.
 * To avoid having to copy data from other paths into the root in order to add it to the resulting
 * zip file, the user can specify extra files to be added into the root on generation. The user must specify
 * a final name for each extra file object.
 *//*from   ww  w  .  j  ava2s.  com*/
public ZipGenerator(final File rootFolder, final Pair<String, File>... extraFilesToAddIntoRoot)
        throws IOException {
    this.rootFolder = rootFolder;
    this.otherFiles = extraFilesToAddIntoRoot;

    // writing in the PipedOutputStream will pass the data
    // into the PipedInputStream when completed
    pos = new PipedOutputStream();
    pis = new PipedInputStream(pos);
    zip = new ZipOutputStream(pos);
