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

Usage

From source file:com.arcanix.php.phar.PharEntry.java

public PharEntry(final File file, final String localPath, final PharCompression pharCompression)
        throws IOException {
    this.file = file;
    this.localPath = localPath;
    this.pharCompression = pharCompression;

    byte[] uncompressedBytes = Files.readAllBytes(this.file.toPath());
    this.checksum = new CRC32();
    this.checksum.update(uncompressedBytes);

    ByteArrayOutputStream compressed = new ByteArrayOutputStream();

    OutputStream compressor = null;
    try {//from   ww  w . jav  a  2s.c  om
        compressor = getCompressorOutputStream(compressed);
        Files.copy(this.file.toPath(), compressor);
        compressor.flush();
    } finally {
        compressor.close();
    }

    this.compressedBytes = compressed.toByteArray();
