      extended by com.google.gson.FieldNamingPolicy
All Implemented Interfaces:
Serializable, Comparable<FieldNamingPolicy>

public enum FieldNamingPolicy
extends Enum<FieldNamingPolicy>

An enumeration that defines a few standard naming conventions for JSON field names. This enumeration should be used in conjunction with GsonBuilder to configure a Gson instance to properly translate Java field names into the desired JSON field names.

Enum Constant Summary
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 (_).
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.
 
Method Summary
static FieldNamingPolicy valueOf(String name)
          Returns the enum constant of this type with the specified name.
static FieldNamingPolicy[] values()
          Returns an array containing the constants of this enum type, in the order they're declared.

Enum Constant Detail

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":


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":

Method Detail

values

public static final FieldNamingPolicy[] values()
Returns an array containing the constants of this enum type, in the order they're 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're 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
