Enum Constant Detail

• IDENTITY

  public static final FieldNamingPolicy IDENTITY

  Using this naming policy with Gson will ensure that the field name is unchanged.

• UPPER_CAMEL_CASE

  public static final FieldNamingPolicy UPPER_CAMEL_CASE

  Using this naming policy with Gson will ensure that the first "letter" of the Java field name is capitalized when serialized to its JSON form.

  Here's a few examples of the form "Java Field Name" ---> "JSON Field Name":

  • someFieldName ---> SomeFieldName
  • _someFieldName ---> _SomeFieldName

• UPPER_CAMEL_CASE_WITH_SPACES

  public static final FieldNamingPolicy UPPER_CAMEL_CASE_WITH_SPACES

  Using this naming policy with Gson will ensure that the first "letter" of the Java field name is capitalized when serialized to its JSON form and the words will be separated by a space.

  Here's a few examples of the form "Java Field Name" ---> "JSON Field Name":

  • someFieldName ---> Some Field Name
  • _someFieldName ---> _Some Field Name

  Since:

  1.4

• LOWER_CASE_WITH_UNDERSCORES

  public static final FieldNamingPolicy LOWER_CASE_WITH_UNDERSCORES

  Using this naming policy with Gson will modify the Java Field name from its camel cased form to a lower case field name where each word is separated by an underscore (_).

  Here's a few examples of the form "Java Field Name" ---> "JSON Field Name":

  • someFieldName ---> some_field_name
  • _someFieldName ---> _some_field_name
  • aStringField ---> a_string_field
  • aURL ---> a_u_r_l

• LOWER_CASE_WITH_DASHES

  public static final FieldNamingPolicy LOWER_CASE_WITH_DASHES

  Using this naming policy with Gson will modify the Java Field name from its camel cased form to a lower case field name where each word is separated by a dash (-).

  Here's a few examples of the form "Java Field Name" ---> "JSON Field Name":

  • someFieldName ---> some-field-name
  • _someFieldName ---> _some-field-name
  • aStringField ---> a-string-field
  • aURL ---> a-u-r-l

  Using dashes in JavaScript is not recommended since dash is also used for a minus sign in expressions. This requires that a field named with dashes is always accessed as a quoted property like myobject['my-field']. Accessing it as an object field myobject.my-field will result in an unintended javascript expression.

  Since:

  1.4

• LOWER_CASE_WITH_DOTS

  public static final FieldNamingPolicy LOWER_CASE_WITH_DOTS

  Using this naming policy with Gson will modify the Java Field name from its camel cased form to a lower case field name where each word is separated by a dot (.).

  Here's a few examples of the form "Java Field Name" ---> "JSON Field Name":

  • someFieldName ---> some.field.name
  • _someFieldName ---> _some.field.name
  • aStringField ---> a.string.field
  • aURL ---> a.u.r.l

  Using dots in JavaScript is not recommended since dot is also used for a member sign in expressions. This requires that a field named with dots is always accessed as a quoted property like myobject['my.field']. Accessing it as an object field myobject.my.field will result in an unintended javascript expression.

Method Detail

• values

  public static FieldNamingPolicy[] values()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

  for (FieldNamingPolicy c : FieldNamingPolicy.values())
      System.out.println(c);
  

  Returns:

  an array containing the constants of this enum type, in the order they are declared

• valueOf

  public static FieldNamingPolicy valueOf​(String name)

  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:

  name - the name of the enum constant to be returned.

  Returns:

  the enum constant with the specified name

  Throws:

  IllegalArgumentException - if this enum type has no constant with the specified name

  NullPointerException - if the argument is null
