Enum Constant Detail

type_url

public static final StateField type_url

The field to store TypeUrl of an entity state.

This type information is used to deserialize binary data stored in the StateField.bytes field.

See Also:

TypeUrl

bytes

public static final StateField bytes

The field to store the serialized bytes of the entity state.

This is the way to store objects of custom types within a strongly-typed storage (e.g. relational database) and make the read/write operations easy requiring no reflection.

Method Detail

values

public static StateField[] 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 (StateField c : StateField.values())
    System.out.println(c);

Returns:

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

valueOf

public static StateField valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null
