011/** 
012 *  File and text-string SBML writer.
013 <p>
014 * <p style='color: #777; font-style: italic'>
015This class of objects is defined by libSBML only and has no direct
016equivalent in terms of SBML components.  This class is not prescribed by
017the SBML specifications, although it is used to implement features
018defined in SBML.
019</p>
020
021 <p>
022 * The {@link SBMLWriter} class is the converse of {@link SBMLReader}, and provides the
023 * main interface for serializing SBML models into XML and writing the
024 * result to an output stream or to files and text strings.  The methods 
025 * for writing SBML all take an {@link SBMLDocument} object and a destination.  
026 * They return a boolean or integer value to indicate success or failure.
027 <p>
028 * <h2>Support for writing compressed files</h2>
029 <p>
030 * LibSBML provides support for writing (as well as reading) compressed
031 * SBML files.  The process is transparent to the calling
032 * application&mdash;the application does not need to do anything
033 * deliberate to invoke the functionality.  If a given SBML filename ends
034 * with an extension for the <em>gzip</em>, <em>zip</em> or <em>bzip2</em> compression
035 * formats (respectively, <code>&quot;.gz&quot;</code>,
036 * <code>&quot;.zip&quot;</code>, or <code>&quot;.bz2&quot;</code>),
037 * then the methods
038 * {@link SBMLWriter#writeSBML(SBMLDocument, String)}
039 * and {@link SBMLReader#readSBML(String)}
040 * will automatically compress and decompress the file while writing and
041 * reading it.  If the filename has no such extension, it
042 * will be written and read uncompressed as normal.
043 <p>
044 * The compression feature requires that the <em>zlib</em> (for <em>gzip</em> and 
045 * <em>zip</em> formats) and/or <em>bzip2</em> (for <em>bzip2</em> format) be available on the
046 * system running libSBML, and that libSBML was configured with their
047 * support compiled-in.  Please see the libSBML <a href='../../../libsbml-installation.html'>installation instructions</a> for 
048 * more information about this.  The methods
049 * {@link SBMLWriter#hasZlib()} and
050 * {@link SBMLWriter#hasBzip2()}
051 * can be used by an application to query at run-time whether support
052 * for the compression libraries is available in the present copy of
053 * libSBML.
054 <p>
055 * Support for compression is not mandated by the SBML standard, but
056 * applications may find it helpful, particularly when large SBML models
057 * are being communicated across data links of limited bandwidth.

103   * Equality comparison method for SBMLWriter.
104   * <p>
105   * Because the Java methods for libSBML are actually wrappers around code
106   * implemented in C++ and C, certain operations will not behave as
107   * expected.  Equality comparison is one such case.  An instance of a
108   * libSBML object class is actually a <em>proxy object</em>
109   * wrapping the real underlying C/C++ object.  The normal <code>==</code>
110   * equality operator in Java will <em>only compare the Java proxy objects</em>,
111   * not the underlying native object.  The result is almost never what you
112   * want in practical situations.  Unfortunately, Java does not provide a
113   * way to override <code>==</code>.
114   *  <p>
115   * The alternative that must be followed is to use the
116   * <code>equals()</code> method.  The <code>equals</code> method on this
117   * class overrides the default java.lang.Object one, and performs an
118   * intelligent comparison of instances of objects of this class.  The
119   * result is an assessment of whether two libSBML Java objects are truly 
120   * the same underlying native-code objects.
121   *  <p>
122   * The use of this method in practice is the same as the use of any other
123   * Java <code>equals</code> method.  For example,
124   * <em>a</em><code>.equals(</code><em>b</em><code>)</code> returns
125   * <code>true</code> if <em>a</em> and <em>b</em> are references to the
126   * same underlying object.

129   * instance will be compared
