Field Details

CHARACTER_ESCAPE_HANDLER

public static final String CHARACTER_ESCAPE_HANDLER

The Constant CHARACTER_ESCAPE_HANDLER. Allows for customization of character escaping when marshalling. Value should be an implementation of org.eclipse.persistence.oxm.CharacterEscapeHandler.

See Also:

• CharacterEscapeHandler
• Constant Field Values

INDENT_STRING

public static final String INDENT_STRING

The Constant INDENT_STRING. Property used to set the string used when indenting formatted marshalled documents. The default for formatted documents is " " (three spaces).

See Also:

JSON_ATTRIBUTE_PREFIX

public static final String JSON_ATTRIBUTE_PREFIX

The name of the property used to specify a value that will be prepended to all keys that are mapped to an XML attribute. By default there is no attribute prefix. There is no effect when media type is "application/xml". When this property is specified at the JAXBContext level all instances of Marshaller and Unmarshaller will default to this attribute prefix.

See Also:

• JAXBContextProperties.JSON_ATTRIBUTE_PREFIX
• UnmarshallerProperties.JSON_ATTRIBUTE_PREFIX
• Constant Field Values

JSON_INCLUDE_ROOT

public static final String JSON_INCLUDE_ROOT

The name of the property used to specify in the root node should be included in the message (default is true). There is no effect when media type is "application/xml". When this property is specified at the JAXBContext level all instances of Marshaller and Unmarshaller will default to this setting.

See Also:

• JAXBContextProperties.JSON_INCLUDE_ROOT
• UnmarshallerProperties.JSON_INCLUDE_ROOT
• Constant Field Values

JSON_NAMESPACE_SEPARATOR

public static final String JSON_NAMESPACE_SEPARATOR

The name of the property used to specify the character (default is '.') that separates the prefix from the key name. It is only used if namespace qualification has been enabled be setting a namespace prefix mapper. When this property is specified at the JAXBContext level all instances of Marshaller and Unmarshaller will default to this setting.

See Also:

• JAXBContextProperties.JSON_NAMESPACE_SEPARATOR
• UnmarshallerProperties.JSON_NAMESPACE_SEPARATOR
• Constant Field Values

JSON_VALUE_WRAPPER

public static final String JSON_VALUE_WRAPPER

The name of the property used to specify the key that will correspond to the property mapped with @XmlValue. This key will only be used if there are other mapped properties. When this property is specified at the JAXBContext level all instances of Marshaller and Unmarshaller will default to this setting.

See Also:

• JAXBContextProperties.JSON_VALUE_WRAPPER
• UnmarshallerProperties.JSON_VALUE_WRAPPER
• Constant Field Values

MEDIA_TYPE

public static final String MEDIA_TYPE

The name of the property used to specify the type of binding to be performed. When this property is specified at the JAXBContext level all instances of Marshaller and Unmarshaller will default to this media type. Supported values are:

• MediaType.APPLICATION_XML (default)
• MediaType.APPLICATION_JSON
• "application/xml"
• "application/json"

See Also:

• JAXBContextProperties.MEDIA_TYPE
• UnmarshallerProperties.MEDIA_TYPE

NAMESPACE_PREFIX_MAPPER

public static final String NAMESPACE_PREFIX_MAPPER

The Constant NAMESPACE_PREFIX_MAPPER. Provides a means to customize the namespace prefixes used while marshalling to XML. Used for both marshal and unmarshal when mediaType is set to "application/json". Value is either a Map of URIs to prefixes, or an implementation of org.eclipse.persistence.oxm.NamespacePrefixMapper.

See Also:

• NamespacePrefixMapper
• Constant Field Values

JSON_MARSHAL_EMPTY_COLLECTIONS

public static final String JSON_MARSHAL_EMPTY_COLLECTIONS

The Constant JSON_MARSHAL_EMPTY_COLLECTIONS. If true an empty or null collection will be marshalled as null or empty array, if false both will be represented as an absent node.

See Also:

• Constant Field Values

JSON_REDUCE_ANY_ARRAYS

public static final String JSON_REDUCE_ANY_ARRAYS

The Constant JSON_REDUCE_ANY_ARRAYS. If true arrays that have just one item in them will be reduced and marshalled as a single item and not as a collection. ie: no [ ] in the marshalled JSON Default is false so all collections (even size 1) will have the [ ] around them.

See Also:

• Constant Field Values

JSON_USE_XSD_TYPES_WITH_PREFIX

public static final String JSON_USE_XSD_TYPES_WITH_PREFIX

If there should be xsd prefix when using simple types, e.g. xsd.int.

See Also:

• JAXBContextProperties.JSON_USE_XSD_TYPES_WITH_PREFIX
• UnmarshallerProperties.JSON_USE_XSD_TYPES_WITH_PREFIX
• Constant Field Values

JSON_TYPE_COMPATIBILITY

public static final String JSON_TYPE_COMPATIBILITY

If we should treat unqualified type property in JSON as MOXy type discriminator.

See Also:

• UnmarshallerProperties.JSON_TYPE_COMPATIBILITY
• Constant Field Values

JSON_TYPE_ATTRIBUTE_NAME

public static final String JSON_TYPE_ATTRIBUTE_NAME

Override default type property name for JSON as MOXy type discriminator. Settings from binding file have higher priority.

Example

Given the following property

 marshaller.setProperty(MarshallerProperties.JSON_TYPE_ATTRIBUTE_NAME, "mytype");
 

If the property is set the JSON output will be:

 ...
 {
      "mytype": "phone",
      "contactId": 3,
      "number": "987654321"
 }
 ...
 

for following object model

 @XmlSeeAlso({Address.class, Phone.class})
 public class Contact {

      public int contactId;
      ...
 

 public class Phone extends Contact{

      public String number;
      ...
 

If the property is not set (default value) the JSON output will be:

 ...
 {
      "type": "phone",
      "contactId": 3,
      "number": "987654321"
 }
 ...
 

Unmarshaller will use it as type discriminator to select right child class.

See Also:

• JAXBContextProperties.JSON_TYPE_ATTRIBUTE_NAME
• UnmarshallerProperties.JSON_TYPE_ATTRIBUTE_NAME
• Constant Field Values

JSON_DISABLE_NESTED_ARRAY_NAME

public static final String JSON_DISABLE_NESTED_ARRAY_NAME

Disable generation of "item" name in nested arrays in JSON. Settings from binding file have higher priority.

Example

Given the following property

 marshaller.setProperty(MarshallerProperties.JSON_DISABLE_NESTED_ARRAY_NAME, "false");
 

If the property value is set to false (default) the JSON output will be:

 ...
 "char2dArray":[
      {"item":["a","b","c","d"]},
      {"item":["e","f","g","h"]}
 ]
 ...
 

for following object model

 ...
 @XmlElement(name="char2dArray")
 private char[][] char2dArray;
 ...
 

If the property value is set to true (default) the JSON output will be:

 ...
 "char2dArray": [
      ["a","b","c","d"],
      ["e","f","g","h"]
 ]
 ...
 

See Also:

• Constant Field Values

OBJECT_GRAPH

public static final String OBJECT_GRAPH

See Also:

• Constant Field Values

JSON_WRAPPER_AS_ARRAY_NAME

public static final String JSON_WRAPPER_AS_ARRAY_NAME

The Constant JSON_WRAPPER_AS_ARRAY_NAME. If true the grouping element will be used as the JSON key. There is no effect when media type is "application/xml". When this property is specified at the JAXBContext level all instances of Marshaller and Unmarshaller will default to this.

Example

Given the following class:

 @XmlAccessorType(XmlAccessType.FIELD)
 public class Customer {

     @XmlElementWrapper(name="phone-numbers")
     @XmlElement(name="phone-number")
     private List<PhoneNumber> phoneNumbers;

 }
 

If the property is set to false (the default) the JSON output will be:

 {
     "phone-numbers" : {
         "phone-number" : [ {
             ...
         }, {
             ...
         }]
     }
 }
 

And if the property is set to true, then the JSON output will be:

 {
     "phone-numbers" : [ {
         ...
     }, {
         ...
     }]
 }

• UnmarshallerProperties.BEAN_VALIDATION_NO_OPTIMISATION
• Constant Field Values

MOXY_LOGGING_LEVEL

public static final String MOXY_LOGGING_LEVEL

MOXY_LOG_PAYLOAD

public static final String MOXY_LOG_PAYLOAD

Property for logging Entities content during marshalling/unmarshalling operation in MOXy. It calls toString() method from entity. This is to make maintenance easier and to allow for debugging to check marshalled/unmarshalled content. Use it carefully. It can produce high amount of data in the log files. Usage: set to Boolean.TRUE to enable payload logging, set to Boolean.FALSE to disable it. It can be set via system property with name "eclipselink.logging.payload.moxy" too.
