/** * Constructs a Gson object with the default configuration. The default configuration has the * following settings://from www . j a va2s . c om * <ul> * <li>By default, YaGson's detects all self-references and the duplicate objects in the whole references graph * of the serialized object. All such objects except the first one are emitted as link-like references, see * {@link ReferencesPolicy#DUPLICATE_OBJECTS}. Although this policy may be changed to the alternative ones by * {@link YaGsonBuilder#setReferencesPolicy(ReferencesPolicy)}, it is not recommended in case of arbitrary objects, * as the functionality of the deserialized objects may be broken.</li> * <li>By default, the type information is emitted as {@literal @type/@value} wrappers when the actual types * would be lost otherwise, i.e. when the known de-serialization type is less specific than the actual class * of an object or its part being serialized. Use * {@link YaGsonBuilder#setTypeInfoPolicy(TypeInfoPolicy)} to change it if necessary.</li> * <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 * {@link GsonBuilder#setPrettyPrinting()}. </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 {@link GsonBuilder#serializeNulls()}.</li> * <li>The default Date format is same as {@link java.text.DateFormat#DEFAULT}. This format * ignores the millisecond portion of the date during serialization. You can change * this by invoking {@link GsonBuilder#setDateFormat(int)} or * {@link GsonBuilder#setDateFormat(String)}. </li> * <li>By default, Gson ignores the {@link com.google.gson.annotations.Expose} annotation. * You can enable Gson to serialize/deserialize only those fields marked with this annotation * through {@link GsonBuilder#excludeFieldsWithoutExposeAnnotation()}. </li> * <li>By default, Gson ignores the {@link com.google.gson.annotations.Since} annotation. You * can enable Gson to use this annotation through {@link GsonBuilder#setVersion(double)}.</li> * <li>The default field naming policy for the output Json is same as in Java. So, a Java class * field <code>versionNumber</code> will be output as <code>"versionNumber"</code> in * Json. The same rules are applied for mapping incoming Json to the Java classes. You can * change this policy through {@link GsonBuilder#setFieldNamingPolicy(FieldNamingPolicy)}.</li> * <li>By default, YaGson excludes <code>static</code> fields from * consideration for serialization and deserialization, but serializes most of <code>transient</code> * fields. * You can change this behavior through * {@link GsonBuilder#excludeFieldsWithModifiers(int...)}.</li> * </ul> */ public YaGson() { super(Excluder.DEFAULT.forReferencesPolicy(References.defaultPolicy()), FieldNamingPolicy.IDENTITY, Collections.<Type, InstanceCreator<?>>emptyMap(), false, TypeInfoPolicy.defaultPolicy().isEnabled(), DEFAULT_JSON_NON_EXECUTABLE, !TypeInfoPolicy.defaultPolicy().isEnabled(), // disable htmlSafe if types are printed false, false, LongSerializationPolicy.DEFAULT, Collections.<TypeAdapterFactory>emptyList(), References.defaultPolicy(), TypeInfoPolicy.defaultPolicy()); }
