<P>
This is the main class for using Gson. Gson is typically used by first constructing a
Gson instance and then invoking <A HREF="../../../com/google/gson/Gson.html#toJson(java.lang.Object)"><CODE>toJson(Object)</CODE></A> or <A HREF="../../../com/google/gson/Gson.html#fromJson(java.lang.String, java.lang.Class)"><CODE>fromJson(String, Class)</CODE></A>
methods on it.
<p>You can create a Gson instance by invoking <code>new Gson()</code> if the default configuration
is all you need. You can also use <A HREF="../../../com/google/gson/GsonBuilder.html" title="class in com.google.gson"><CODE>GsonBuilder</CODE></A> to build a Gson instance with various
configuration options such as versioning support, pretty printing, custom
<A HREF="../../../com/google/gson/JsonSerializer.html" title="interface in com.google.gson"><CODE>JsonSerializer</CODE></A>s, <A HREF="../../../com/google/gson/JsonDeserializer.html" title="interface in com.google.gson"><CODE>JsonDeserializer</CODE></A>s, and <A HREF="../../../com/google/gson/InstanceCreator.html" title="interface in com.google.gson"><CODE>InstanceCreator</CODE></A>s.</p>
<p>Here is an example of how Gson is used for a simple Class:
<pre>
Gson gson = new Gson(); // Or use new GsonBuilder().create();
MyType target = new MyType();
String json = gson.toJson(target); // serializes target to Json
MyType target2 = gson.fromJson(json, MyType.class); // deserializes json into target2
</pre></p>
<p>If the object that your are serializing/deserializing is a <code>ParameterizedType</code>
(i.e. contains at least one type parameter and may be an array) then you must use the
<A HREF="../../../com/google/gson/Gson.html#toJson(java.lang.Object, java.lang.reflect.Type)"><CODE>toJson(Object, Type)</CODE></A> or <A HREF="../../../com/google/gson/Gson.html#fromJson(java.lang.String, java.lang.reflect.Type)"><CODE>fromJson(String, Type)</CODE></A> method. Here is an
example for serializing and deserialing a <code>ParameterizedType</code>:
<pre>
Type listType = new TypeToken<List<String>>() {}.getType();
List<String> target = new LinkedList<String>();
target.add("blah");
Gson gson = new Gson();
String json = gson.toJson(target, listType);
List<String> target2 = gson.fromJson(json, listType);
</pre></p>

<DD>Constructs a Gson object with default configuration. The default configuration has the
following settings:
<ul>
<li>The JSON generated by <code>toJson</code> methods is in compact representation. This
means that all the unneeded white-space is removed. You can change this behavior with
<A HREF="../../../com/google/gson/GsonBuilder.html#setPrettyPrinting()"><CODE>GsonBuilder.setPrettyPrinting()</CODE></A>. </li>
<li>The generated JSON omits all the fields that are null. Note that nulls in arrays are
kept as is since an array is an ordered list. Moreover, if a field is not null, but its
generated JSON is empty, the field is kept. You can configure Gson to serialize null values
by setting <A HREF="../../../com/google/gson/GsonBuilder.html#serializeNulls()"><CODE>GsonBuilder.serializeNulls()</CODE></A>.</li>
<li>Gson provides default serialization and deserialization for Enums, <A HREF="http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Map.html?is-external=true" title="class or interface in java.util"><CODE>Map</CODE></A>,

<DL>
<DD>This method is used to get an alternate type adapter for the specified type. This is used
to access a type adapter that is overridden by a <A HREF="../../../com/google/gson/TypeAdapterFactory.html" title="interface in com.google.gson"><CODE>TypeAdapterFactory</CODE></A> that you
may have registered. This features is typically used when you want to register a type
adapter that does a little bit of work but then delegates further processing to the Gson
default type adapter. Here is an example:
<p>Let's say we want to write a type adapter that counts the number of objects being read
from or written to JSON. We can achieve this by writing a type adapter factory that uses
the <code>getDelegateAdapter</code> method:
<pre> <code>class StatsTypeAdapterFactory implements TypeAdapterFactory {
public int numReads = 0;
public int numWrites = 0;
public &lt;T&gt; TypeAdapter&lt;T&gt; create(Gson gson, TypeToken&lt;T&gt; type) {
final TypeAdapter&lt;T&gt; delegate = gson.getDelegateAdapter(this, type);
return new TypeAdapter&lt;T&gt;() {
public void write(JsonWriter out, T value) throws IOException {
++numWrites;
delegate.write(out, value);
}
public T read(JsonReader in) throws IOException {
++numReads;
return delegate.read(in);
}
};
}
}
</code> </pre>
This factory can now be used like this:
<pre> <code>StatsTypeAdapterFactory stats = new StatsTypeAdapterFactory();
Gson gson = new GsonBuilder().registerTypeAdapterFactory(stats).create();
// Call gson.toJson() and fromJson methods on objects
System.out.println("Num JSON reads" + stats.numReads);
System.out.println("Num JSON writes" + stats.numWrites);
</code></pre>
Note that since you can not override type adapter factories for String and Java primitive
types, our stats factory will not count the number of String or primitives that will be
read or written.
