98Reimplementation of <CODE>java.util.zip.ZipOutputStream</CODE> that does handle the extended
99 functionality of this package, especially internal/external file
100 attributes and extra fields with different layouts for local file
101 data and central directory entries.
102
103 <p>This class will try to use <CODE>RandomAccessFile</CODE> when you know that the output is going to go to a
104 file.</p>
105
106 <p>If RandomAccessFile cannot be used, this implementation will use
107 a Data Descriptor to store size and CRC information for <A HREF="../../../../org/apache/tools/zip/ZipOutputStream.html#DEFLATED"><CODE>DEFLATED</CODE></A> entries, this means, you don't need to
108 calculate them yourself. Unfortunately this is not possible for
109 the <A HREF="../../../../org/apache/tools/zip/ZipOutputStream.html#STORED"><CODE>STORED</CODE></A> method, here setting the CRC and
110 uncompressed size information is required before <A HREF="../../../../org/apache/tools/zip/ZipOutputStream.html#putNextEntry(org.apache.tools.zip.ZipEntry)"><CODE>putNextEntry</CODE></A> can be called.</p>
