Concatenate
public static final KeyExpression.FanType Concatenate
Convert a repeated field into a single list. This does not cause the number of index values to increase.
-
FanOut
public static final KeyExpression.FanType FanOut
Create an index value for each value of the field.

None
public static final KeyExpression.FanType None
Nothing, only allowed with scalar fields.

values
public static KeyExpression.FanType[] 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 (KeyExpression.FanType c : KeyExpression.FanType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static KeyExpression.FanType 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 nameNullPointerException
- if the argument is null
-
valueOf
public static KeyExpression.FanType valueOf(RecordMetaDataProto.Field.FanType fanType) throws KeyExpression.DeserializationException
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:
fanType
- 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 nameNullPointerException
- if the argument is nullKeyExpression.DeserializationException
