Enum Constant Summary

Enum Constants
Enum Constant	Description
`AUTO_DETECT_XSI_TYPE`	Feature that enables automatic conversion of logical property name `"xsi:type"` into matching XML name where "type" is the local name and "xsi" prefix is bound to URI `XMLConstants.W3C_XML_SCHEMA_INSTANCE_NS_URI`, and output is indicated to be done as XML Attribute.
`UNWRAP_ROOT_OBJECT_NODE`	Feature that determines writing of root values of type `ObjectNode` (`JsonNode` subtype that represents Object content values), regarding XML output.
`WRITE_NULLS_AS_XSI_NIL`	Feature that controls whether serialization of Java `null` values adds XML attribute of `xsi:nil`, as defined by XML Schema (see this article for details) or not.
`WRITE_STANDALONE_YES_TO_XML_DECLARATION`	Feature that controls whether XML declaration should include the standalone attribute when generator is initialized (true) or not (false).
`WRITE_XML_1_1`	Feature that controls whether output should be done as XML 1.1; if so, certain aspects may differ from default (1.0) processing: for example, XML declaration will be automatically added (regardless of setting `WRITE_XML_DECLARATION`) as this is required for reader to know to use 1.1 compliant handling.
`WRITE_XML_DECLARATION`	Feature that controls whether XML declaration should be written before when generator is initialized (true) or not (false)
`WRITE_XML_SCHEMA_CONFORMING_FLOATS`	Feature that determines how floating-point infinity values are serialized.

- Enum Constant Detail
  - WRITE_XML_DECLARATION
```
public static final ToXmlGenerator.Feature WRITE_XML_DECLARATION
```
    Feature that controls whether XML declaration should be written before when generator is initialized (true) or not (false)
  - WRITE_STANDALONE_YES_TO_XML_DECLARATION
```
public static final ToXmlGenerator.Feature WRITE_STANDALONE_YES_TO_XML_DECLARATION
```
    Feature that controls whether XML declaration should include the standalone attribute when generator is initialized (true) or not (false). Only honored when WRITE_XML_DECLARATION is enabled
    
    Since:
    
    2.19
  - WRITE_XML_1_1
```
public static final ToXmlGenerator.Feature WRITE_XML_1_1
```
    Feature that controls whether output should be done as XML 1.1; if so, certain aspects may differ from default (1.0) processing: for example, XML declaration will be automatically added (regardless of setting WRITE_XML_DECLARATION) as this is required for reader to know to use 1.1 compliant handling. XML 1.1 can be used to allow quoted control characters (Ascii codes 0 through 31) as well as additional linefeeds and name characters.
  - WRITE_NULLS_AS_XSI_NIL
```
public static final ToXmlGenerator.Feature WRITE_NULLS_AS_XSI_NIL
```
    Feature that controls whether serialization of Java null values adds XML attribute of `xsi:nil`, as defined by XML Schema (see this article for details) or not. If enabled, `xsi:nil` attribute will be added to the empty element; if disabled, it will not.
    Default setting is disabled in Jackson 2.x for backwards compatibility: but will be changed in 3.0 to enabled.
    
    Since:
    
    2.10
  - UNWRAP_ROOT_OBJECT_NODE
```
public static final ToXmlGenerator.Feature UNWRAP_ROOT_OBJECT_NODE
```
    Feature that determines writing of root values of type ObjectNode (JsonNode subtype that represents Object content values), regarding XML output. If enabled and ObjectNode has exactly one entry (key/value pair), then key of that entry is used as the root element name (and value is written as contents. Otherwise (if feature disabled, or if root ObjectNode has any other number of key/value entries, root element name is determined using normal logic (either explicitly configured, or ObjectNode otherwise).
    Default setting is disabled in Jackson 2.x, for backwards compatibility: but will be changed in 3.0 to enabled.
    
    Since:
    
    2.13
  - AUTO_DETECT_XSI_TYPE
```
public static final ToXmlGenerator.Feature AUTO_DETECT_XSI_TYPE
```
    Feature that enables automatic conversion of logical property name "xsi:type" into matching XML name where "type" is the local name and "xsi" prefix is bound to URI XMLConstants.W3C_XML_SCHEMA_INSTANCE_NS_URI, and output is indicated to be done as XML Attribute. This is mostly desirable for Polymorphic handling where it is difficult to specify XML Namespace for type identifier
    Default setting is disabled in Jackson 2.x for backwards compatibility: but will be changed in 3.0 to enabled.
    
    Since:
    
    2.17
  - WRITE_XML_SCHEMA_CONFORMING_FLOATS
```
public static final ToXmlGenerator.Feature WRITE_XML_SCHEMA_CONFORMING_FLOATS
```
    Feature that determines how floating-point infinity values are serialized.
    By default, Float.POSITIVE_INFINITY and Double.POSITIVE_INFINITY are serialized as Infinity, and Float.NEGATIVE_INFINITY and Double.NEGATIVE_INFINITY are serialized as -Infinity. This is the representation that Java normally uses for these values (see Float.toString(float) and Double.toString(double)), but JAXB and other XML Schema-conforming readers won't understand it.
    With this feature enabled, these values are instead serialized as INF and -INF, respectively. This is the representation that XML Schema and JAXB use (see the XML Schema primitive types float and double).
    When deserializing, Jackson always understands both representations, so there is no corresponding FromXmlParser.Feature.
    Feature is disabled by default in Jackson 2.x for backwards compatibility: but will be changed in 3.0 to enabled.
    
    Since:
    
    2.17
